  2. For the first time, scientists have observed ripples in the fabric of spacetime, called gravitational waves, arriving at Earth from a cataclysmic event in the distant universe. This observation confirms a major prediction of Albert Einstein's general theory of relativity, published in 1916, and opens an unprecedented new window onto the cosmos.

  3. Chad Hanna, assistant professor of physics at Penn State and co-hire of the Institute for CyberScience (ICS), will deliver a talk entitled "Gravitational Wave Astronomy's Next Frontier in Computation" about his breakthrough discovery of gravitational waves, a phenomenon predicted 100 years ago by Albert Einstein. The talk will be from 3:30 to 5 p.m. on April 17 in 320 Whitmore Lab.
  4. Less than four months after the historic first-ever detection of gravitational waves, scientists on a team that includes Penn State University physicists and astronomers now have detected another gravitational wave washing over the Earth. "I would never have guessed that we would be so fortunate to have, not only one, but two definitive binary black-hole detections within the first few months ...
  5. The center's faculty are prominent participants in eight major international projects that are making rapid-response observations — using extremely high-energy protons and nuclei, neutrinos, gamma-rays, X-rays and gravitational waves — as quickly as possible after gravitational waves are discovered by the LIGO and Virgo detectors.

  6. For the first time, three detectors have tracked the gravitational waves emitted by a merger of two black holes -- a critical new capability that allows scientists to more closely locate a gravitational wave's birthplace in space. Gravitational waves are ripples in space and time created when two massive, compact objects such as black holes merge.

  7. A record-breaking billions of light-years from Earth, gravitational waves produced by the birth of a massive black hole have been detected by the Laser Interferometer Gravitational-wave Observatory (LIGO), an international project that includes Penn State scientists. This achievement indicates that LIGO's success in detecting gravitational waves has opened the door to an entirely new way to ...
  8. Oct 9, 2024A heavy use of computational tools can help to detect what has yet to be discovered, according to Chad Hanna, professor of physics and of astronomy and astrophysics at Penn State. Hanna, who started at the University in 2014 and is a Penn State Institute for Computational and Data Sciences (ICDS) co-hire, is working to discover astrophysical events — such as gravitational waves — caused by ...
  9. UNIVERSITY PARK, Pa. — A team of Penn State astronomers has been instrumental in the confirmation of a scientific theory that gamma ray bursts are caused by the merging and explosion of two neutron stars.. On Aug. 17, Penn State astronomers in charge of Mission Control for NASA's Swift satellite received a message that LIGO — the Laser Interferometer Gravitational-Wave Observatory ...
  10. There is a hint of this phenomenon found by LIGO in at least one black hole of the GW170104 black-hole system. ... "Some promising gravitational-wave candidates have been identified by both LIGO and Virgo during our preliminary analysis, and we have shared what we currently know with observing partners using telescopes, gamma-ray detectors, and ...
  11. Gravitational waves are ripples in space time produced as aftershocks of huge astronomical events, such as the collision of two black holes. Using a global network of detectors, the research team identified 35 gravitational wave events, bringing the total number of observed events to 90 since detection efforts began in 2015.
