Nation's Largest Scientific Footprint in NASA's WFIRST Mission

February 18, 2016

"Last week, NASA announced plans to move forward on the Wide Field Infrared Survey Telescope. Projected to launch in mid-2020, it has two major missions: discovering secrets of dark energy and dark matter; and worlds beyond our solar system. Three Ohio State researchers, astronomer Scott Gaudi and astrophysicists Chris Hirata and David Weinberg, were named to teams responsible for the critical final design."

"With three leading members of WFIRST's Science Investigation Teams, Ohio State has "the largest scientific footprint in WFIRST of any university in the country," according to Weinberg. Weinberg and Hirata are co-investigators on the team designing WFIRST's single largest program, an enormous map of hundreds of millions of galaxies that will be used to measure the growth of the universe and the clustering of dark matter."

"In the words of WFIRST Project Scientist Neil Gehrels, of NASA's Goddard Space Flight Center, "Ohio State has made enormous contributions to WFIRST. David Weinberg, Chris Hirata and Scott Gaudi are world experts in dark energy and exo-planets, which are its two main science areas. After Hubble and the James Webb Space Telescope, WFIRST is going to be NASA's next great optical and infrared observatory. It would not be moving forward without their seminal work."

Gravitational Waves:
A Black Hole Is Trying to Slap You — Can You Feel It?

February 10, 2016

"Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have found evidence of gravitational waves, a key feature of standard models of how the universe works."

In relation to the big announcement from the LIGO collaboration on Thursday February 11, 2016, CCAPP Postdoc Paul Sutter composed an article describing the physics and importance of gravitational waves.

"In general relativity, space-time is dynamic...It can warp and twist, and bend and flex. It can wave. It responds to the presence of matter and energy, and can influence the behavior of that same matter and energy, exactly as you can. Space-time is a thing."

Astronomers May Have Discovered Brightest Supernova Ever Observed

January 14, 2016

An international team of astronomers including Ohio State Astronomy Professors Krzysztof Stanek, Christopher Kochanek and Todd Thompson, may have discovered the largest supernova ever seen from Earth. The exploding massive star is only 10 miles across at its core, yet is much brighter than the entire output of the Milky Way. "This may be the most powerful supernova ever seen by anybody," said Stanek. The team of astronomers released their findings this week in the journal Science. Ohio State co-authors on the study include John Beacom, professor, physics and astronomy and director, Center for Cosmology and AstroParticle Physics (CCAPP): astronomy graduate students Thomas Holoien; Jonathan Brown; and Gregory Simonian and physics graduate student A. Bianca Danilet.

ASASSN-15lh was first spotted in June of last year using the All Sky Automated Survey for Supernovae (ASAS-SN), based at of Ohio State. The intention of ASAS-SN is to get better statistics on the different types of supernovas and where they are occurring in the cosmos. The survey uses smaller telescopes to scan the sky every two to three days, searching for changes in the heavens. If some new bright object pops up, they'll catch it, and astronomers can then use bigger telescopes to take a better look.

How neutrinos, which barely exist, just ran off with another Nobel Prize

October 6, 2015

Auther John Beacom: "Neutrinos take patience. They're worth it, and the announcement of the 2015 Nobel Prize in Physics recognizes that, following related prizes in 1988, 1995 and 2002. Ironically, these near-undetectable particles can reveal things that cannot be seen any other way.

I could begin by telling you that neutrinos are elementary particles, but that sounds condescending. They're not called elementary because they're easy to understand - they aren't - but because they are seemingly point-like in size, and we can't break them down into smaller constituents. There's no such thing as half a neutrino."

New Research Explores Why The Universe Is Dying

August 10, 2015

An international team of astronomers says new data show energy output measured across more than 200,000 galaxies is only about half as strong as it was 2 billion years ago. Scientists point to this latest study as further evidence that the universe is slowly dying.

John Beacom, a physicist and astronomer at Ohio State University, told NPR that before this comprehensive study, there was always the possibility that scientists didn't have the full picture of how the universe was changing. "This pretty much closes the case: Yes, it's coming to an end," he says.

Inspired by their experiences in college and elsewhere, these Pathfinders are passing by the typical, well-trod career paths and blazing their own trails. We'll explore the unconventional approaches these Big Ten alums and faculty are taking to work.

It's nature's greatest fireworks display: the supernova death of a bright, rare supergiant Wolf-Rayet star -- already several hundred times larger in diameter than our own sun -- which sends white-hot astroparticles flying millions of miles in multiple directions at close to the speed of light.

For Mauricio Bustamante, a postdoctoral fellow at Ohio State's Center for Cosmology and Astroparticle Physics (CCAPP), that sheer magnitude is fascinating. He spends much of his time studying gamma-ray bursts (GRBs), the largest explosions in the universe, via simulations of those levels of energy release.

Cosmic debris: Study looks inside the universe's most powerful explosions

April 10, 2015

A new study provides an inside look at the most powerful explosions in the universe: gamma-ray bursts. These rare explosions happen when extremely massive stars go supernova. The stars' strong magnetic fields channel most of the explosion's energy into two powerful plasma jets, one at each magnetic pole. The jets spray energetic particles for light-years in both directions, at close to light speed.

Mauricio Bustamante, a Fellow of the Center for Cosmology and AstroParticle Physics at Ohio State, explained that the new computer model is a natural outgrowth of recent findings in astroparticle physics, such as the first confirmed cosmic neutrinos detected at the IceCube Neutrino Observatory at the South Pole in 2013.

OSC's New Supercomputer, Ruby Cluster Dedicated

April 9, 2015

Along with the CCAPP Director John Beacom and Science Board member Annika Peter, the Ohio Board of Regents Chencellor John Carey and Ohio State Vice President for Research Caroline Whitacre, as well as other dignitaries helped unveil the Ohio Supercomputer Center's (OSC's) new Ruby supercomputer on April 9, 2015 at the State of Ohio Computer Center on Ohio State's West Campus.

The Ruby Cluster is a 4800-core Intel Xeon processor-based machine with a theoretical peak performance of 144 teraFLOPS, tech-speak for 144 trillion calculations per second. CCAPP is one of two research groups that co-own Ruby with the OSC. This new facility will enable CCAPP researchers to better connect theoretical models to observations of astrophysical processes and objects.

Many thanks to Annika Peter for spearheading the CCAPP partnership with OSC, and to CCAPP and CCAPP faculty who contributed funds to make this possible.

The supercomputer system is named after Ruby Dee, an American actress, playwright, screenwriter, activist, poet and journalist. She was born Ruby Ann Wallace in Cleveland, Ohio, and grew up in New York's Harlem neighborhood. She is perhaps best known for starring in the 1961 film and subsequent stage production of A Raisin in the Sun. Dee and her husband, Ossie Davis, were very active in the Civil Rights Movement, participating in marches and speaking out for racial equality.

TEDx -- The Human Narrative

January 9, 2015

Just two speakers left to reveal for this year's TEDx Ohio State University event on Saturday February 14, 2015, and one of them is Dr. John Beacom!

Dr. Beacom is an internationally-known researcher in physics and astronomy, a popular teacher of introductory courses, and a leader in making scientific advances accessible to non-scientists. He is a Professor in the Ohio State Departments of Physics and Astronomy, as well as the Director of their joint Center for Cosmology and AstroParticle Physics (CCAPP).

His research focuses on neutrinos- almost massless and almost non-interacting particles that pervade the Universe and that can reveal hidden wonders. Such wonders include the core of the Sun, stars that implode, and black holes that are gobbling away (trillions of neutrinos passed invisibly through your eyes as you read that sentence). He has won both the Arts and Sciences Outstanding Teaching Award and the Ohio State Alumni Award for Distinguished Teaching. He frequently makes or hosts presentations on science to audiences ranging from children to retirees. He commutes by bicycle year-round, does not own a cell phone, and claims to see neutrinos.

Testing gravity using cosmic voids

November 20, 2014

Astrophysicists have long searched for ways to find cracks in Einstein's General Theory of Relativity, and thanks to OSU undergraduate Paul Zivick, his advisor Paul Sutter, and an international team of researchers, they have a new avenue available to them.


In a paper recently submitted to the Monthly Notices of the Royal Astronomical Society, Zivick and collaborators outlined how the properties of cosmic voids - the large, empty regions that fill up most of the universe - can provide constraints on modified gravity theories. These theories must agree with predictions from General Relativity in high-density environments in order to pass stringent tests, but in low-density regions like voids the differences between the theories are much larger.


Zivick's work predicted that upcoming galaxy surveys will be able to distinguish modified gravity models better with voids than with traditional probes.

ASAS-SN Discovers its 50th Nearby Supernova

August 22, 2014

One of the major goals of the ASAS-SN project is to produce a complete census of bright, nearby supernovae. In the last few months, using four 14-cm diameter telescopes in Hawaii and two such telescopes in Chile (this expansion was funded mostly by CCAPP), ASAS-SN has been finding about 10 bright (V < 17) supernovae per month. That may not seem like much, compared to more than 1000 SNe found every year, but ASAS-SN is now finding more than half of the brightest SNe. On August 12, ASAS-SN discovered its 50th supernova (33rd since May 1st, 2014), which was annouced via an Astronomer's Telegram . The first author of this telegram is an amateur astronomer from France, Joel Nicolas, whose 41-cm telescope was used to confirm the presence of the supernova. In steady-state, ASAS-SN will likely discover about 100 bright supernovae per year, all of them (and their host galaxies) easily studied with relatively small, 1-4 meter class telescopes.

The Weight of Nothingness

August 22, 2014

The existence of voids, almost entirely empty regions of the cosmic web, has been confirmed by several spectroscopic surveys in the past years. But so far, nobody knew how empty voids really are. By using a technique called gravitational lensing, an international team led by Ohio State CCAPP astrophysicists Peter Melchior and Paul Sutter inferred the mass inside voids - or rather: the absence thereof. This unprecedented measurement confirms earlier predictions and opens a new line of research that will provide insights in how gravity acts on cosmological scales.

It's one of the largest simulations ever performed, and you can visit it. The team created a website devoted to the simulation. The site has both a scientific and a public side, where people can view visualizations of the data or fly through the simulation. With such large simulations, cosmologists can prepare for upcoming galaxy surveys, and comparing this simulation to the real universe helps scientists understand the nature of dark matter and dark energy.

The Measure of Nothing

August 22, 2014

At the largest scales the universe looks like an enormous spider web, with long rope-like filaments, dense clumps of galaxies, and vast empty regions called voids. Ohio State CCAPP astrophysicist Paul Sutter and an international team of collaborators have developed a method to find these voids, and they made a surprising discovery: voids obey a simple mathematical equation. This formula describes the properties of all voids, no matter their size, location, or age. Since voids can now be described by such a simple equation, they offer a brand new way to test theories of cosmology and to help understand the nature of dark matter and dark energy.

Something is Amiss in the Universe: Cosmic Accounting Reveals Missing Light Crisis

July 8, 2014

Something is amiss in the Universe. There appears to be an enormous deficit of ultraviolet light in the cosmic budget. The vast reaches of empty space between galaxies are bridged by tendrils of hydrogen and helium, which can be used as a precise 'light meter.' In a recent study a team of scientists finds that the light from known populations of galaxies and quasars is not nearly enough to explain observations of intergalactic hydrogen. The difference is a stunning 400 percent.

"The great thing about a 400% discrepancy is that you know something is really wrong," commented co-author David Weinberg of The Ohio State University. "We still don't know for sure what it is, but at least one thing we thought we knew about the present day universe isn't true."

Keeping things awesome on the Dark Energy Survey

May 1, 2014

Scientists stay inspired in their sometimes tedious task of inspecting photographs taken in the Dark Energy Survey's ambitious cataloging of one-eighth of the sky. Physicists working on the Dark Energy Survey can expect to pull many an all-nighter. The international collaboration of more than 120 scientists aims to take about 100,000 photographs peering deep into the night sky. Scientists must personally review many of these photos to make sure the experiment is working well, and they've come up with ways to stay motivated while doing so.

Two of the DES researchers, Erin Sheldon of Brookhaven National Laboratory and Peter Melchior of OSU/CCAPP, created the DES Exposure Checker, an online gallery of images from the telescope.

DECam the "focus" of Physics Today cover

April 14, 2014

Every night, on a mountain top high in the Chilean Andes, a new instrument images a portion of the southern sky collecting light emitted by distant galaxies billions of years ago. A team of physicists and astronomers from Ohio State University collaborated with more than a hundred scientists from three continents to build and operate DECam, the Dark Energy Camera. DECam is a large 570 Megapixel camera with 74 custom designed CCDs and a record setting field of view, covering in a single exposure an area of the sky 20 times the size of the full moon as seen from earth. The tools used by the observers to operate DECam, the data acquisition system and the software to monitor and record the status of the instrument were all created by the OSU team led by Prof. Klaus Honscheid.

DECam is used by the Dark Energy Survey collaboration to probe the origin of the accelerating expansion of the universe. This five-year program is designed to uncover the nature of dark energy and to determine whether Einstein's general relativity is valid on the largest scales. The exquisite image quality and operational efficiency required for these studies were demonstrated and optimized during a 10-month science verification period co-chaired by Prof. Honscheid. During this effort, DECam imaged more than 150 sq. degrees of the sky in five different filter bands. Led by CCAPP Fellows Melchior and Huff, the analysis of this data sample, the largest of this kind available to date, is ongoing and first results will soon be published.

More information about DECam and the Dark Energy Survey can be found at

A One-Percent Measure of the Universe

January 8, 2014

Researchers from the Baryon Oscillation Spectroscopic Survey (BOSS) that include CCAPP scientists announced this week that they have measured the distances to galaxies more than six billion light-years away to an unprecedented accuracy of just one percent. The measurements utilized so-called "baryon acoustic oscillations (BAOs)", subtle periodic ripples in the distribution of galaxies, as a standard ruler to measure the cosmic distance to these galaxies. Their measurements place new constraints on the properties of the mysterious "dark energy" thought to permeate empty space, which causes the expansion of the Universe to accelerate. In addition, the team tested the gravity theory at cosmological scales with 10% precision by measuring the velocity fields of the galaxies that were induced by gravity.

Dark Matter 'Wind' May be Warped by the Sun

January 8, 2014

"As WIMPs (weakly interacting massive particles) stream through the solar system, the gravitational pull from the sun alters their individual trajectories, changing their direction and speed," says Samuel Lee of Princeton University.

The sun's pull on dark matter is called gravitational focusing, because the sun acts like a lens to focus the paths of WIMPs toward it. The new study suggests the pattern would be strongly affected by the gravitational effects of the sun, which have so far been dismissed as insubstantial.

CCAPP Faculty, Annika Peter collaborated on this with the three researchers from Princeton (Samuel Lee, Ben Safdi, and Mariangela Lisanti).

Possible Visibility of Milky Way Supernova in Next 50 Years

October 31, 2013

Astronomers at The Ohio State University have calculated the odds that, sometime during the next 50 years, a supernova occurring in our home galaxy will be visible from Earth.

The good news: they've calculated the odds to be nearly 100 percent that such a supernova would be visible to telescopes in the form of infrared radiation.

The bad news: the odds are much lower-dipping to 20 percent or less-that the shining stellar spectacle would be visible to the naked eye in the nighttime sky.

Dark Energy Survey Begins five-year Mission to Map Southern Sky in
Tremendous Detail

Tonight, as the sun sinks below the horizon, the world's most powerful digital camera will once again turn its gleaming eye skyward. Tonight, and for hundreds of nights over the next five years, a team of physicists and astronomers from around the globe will use this remarkable machine to try to answer some of the most fundamental questions about our universe.

On Aug. 31, the Dark Energy Survey (DES) officially began. Scientists on the survey team will systematically map one-eighth of the sky (5000 square degrees) in unprecedented detail. The start of the survey is the culmination of 10 years of planning, building and testing by scientists from 25 institutions in six countries.

The survey's goal is to find out why the expansion of the universe is speeding up, instead of slowing down due to gravity, and to probe the mystery of dark energy, the force believed to be causing that acceleration.

ASAS-SN Discovers its First Supernova

Even in the present day, only human eyes fully survey the sky for the transient, variable and violent events that are crucial probes of the nature and physics of our Universe. The "All-Sky Automated Survey for Supernovae" (ASAS-SN or "Assassin") project plans to change this by (eventually) automatically surveying the entire visible sky every night down to about 17th magnitude, more than 10,000 times deeper than human eye.

Recently, on June 6th, 2013 , The ASAS-SN Project discovered its first supernova, and has just discovered another candidate . You can find the image of the first supernova and article in the Astronomers Telegram below.

Scientists speak a different language to present issues, argue points and convey information. B efore many of these equations make it into a research journal or textbook, they are written in marker, chalk or ink. They are scratched out, erased and rewritten until they speak a universal truth backed by laws of mathematics or physics. We wanted to know what it is like to speak this language, to get lost in an equation. So we asked scientists from three Ohio universities to translate. Read More

Young Intern Co-Authors Paper

While working with Astronomy Grad student Ben Shapee, Alex Talabere, a junior at Metro High School, finished out his internship with CCAPP by being a co-author of the astronomical telegram, "ASAS-SN Discovery of 3 Cataclysmic Variables", along with other scientists from the US, Chile and Poland. The CCAPP internship allowed Alex to contribute to the ongoing ASAS-SN project (All Sky Automated Survey for SuperNovae). This survey is designed to look for the bright supernovae explosions in the nearby universe. This is the first systematic all-sky search for nearby supernovae. This survey uses four wide-field cameras with 20-cm lenses located in Chile and Hawaii. This project is being conducted to gain insight into the progenitor stars of supernovae, and to allow scientists to make the first complete census and detailed characterization of the brightest supernovae in a volume-limited sample of galaxies. Along the way, ASAS-SN will find many other transient objects, including the new cataclysmic variables that Alex helped discover.

Dark energy coffee

Coffee Drives CCAPP

Since its beginnings, CCAPP scientists have been fueled by tens of thousands of espresso shots, brewed with Luck Bros' Coffee. Locally owned and independently operated, Luck Bros' has recently honored this connection with a special roasting, aptly titled "Dark Energy".

The first iteration of Dark Energy is a blend of Central America coffees roasted to different levels and then combined for a complex and balanced experience of brightness, deep lingering notes of chocolate and caramel, and a rich heavy mouth feel. This versatile blend is a solid choice for brewing espresso or drip coffee and best used for cold brewing. Stop in CCAPP for a tasting, or better yet stop by Luck Bros' and say hi to the originator of Dark Energy, owner Andy Luck.
