15:29 Phys.orgDiscovering exoplanets with gravitational waves

In a recent paper in Nature Astronomy, researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam and from the French Alternative Energies and Atomic Energy Commission (CEA) in Saclay, Paris suggest how the planned space-based gravitational-wave observatory LISA can detect exoplanets orbiting white dwarf binaries everywhere in the Milky Way and in the nearby Magellanic Clouds. This new method will overcome certain limitations of current electromagnetic detection techniques and might allow LISA to detect planets down to 50 Earth masses.

The universe might "remember" gravitational waves long after they've passed.That's the premise of a theoretical paper published April 25 in the journal Physical Review D. Gravitational waves, faint ripples in space and time that humanity has only in the past few years managed to detect, tend to pass very quickly. But the authors of the paper showed that after the waves pass, they might leave a region slightly altered -- leaving behind a sort of memory of their crossing.These changes, which the researchers termed "persistent gravitational wave observables," would be even fainter than the gravitational waves themselves, but those effects would last longer. Objects might be shifted slightly out of place. The positions of particles drifting through space might be altered. Even time itself might end up slightly out of

15:56 Phys.orgMini-detectors for the gigantic? Bose-Einstein condensates are currently not able to detect gravitational waves

The gravitational waves created by black holes or neutron stars in the depths of space have been found to reach Earth. Their effects, however, are so small that they can only be observed using kilometer-long measurement facilities. Physicists are therefore discussing whether ultracold and miniscule Bose-Einstein condensates with their ordered quantum properties could also detect these waves. Prof. Ralf Schützhold from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the TU Dresden has studied the basis of these suggestions and writes in the journal Physical Review D that such evidence is far beyond the reach of current methods.

The gravitational waves created in the depths of space indeed reach Earth. Their effects, however, are so small that they could only be observed so far using kilometer-long measurement facilities. Physicists therefore discuss whether Bose-Einstein condensates with their ordered quantum properties could also detect these waves. Astronomers have now looked at these suggestions and have soberly determined that such evidence is far beyond the reach of current methods.

16:02 Photonics.comLIGO and Virgo Announce Four New Gravitational-Wave Detections

The National Science Foundation’s LIGO (Laser Interferometer Gravitational-Wave Observatory) and the European-based Virgo gravitational-wave detector have detected four new black hole merger events. The findings were presented at the Gravitational Wave Physics and Astronomy Workshop in College Park, Md., Dec. 1, 2018. The LIGO and Virgo collaborations have now detected gravitational waves from 10 stellar-mass binary black hole mergers and one merger of neutron stars. LIGO and Virgo have detected four new gravitational waves. Courtesy of the Virgo website at www.virgo-gw.eu. The new events are known as GW170729, GW170809, GW170818, and GW170823, in reference to the dates they were detected. Some of the new events broke records. For example, the new event GW170729 is the most massive and distant gravitational-wave source ever observed. In this coalescence, which happened roughly 5

In 2016, an international team of scientists found definitive evidence—tiny ripples in space known as gravitational waves—to support one of the last remaining untested predictions of Einstein's theory of general relativity. The team used the Laser Interferometer Gravitational-Wave Observatory (LIGO), which has since made several gravitational wave discoveries. Each discovery was possible in part because of a global network of supercomputer clusters, one of which is housed at Penn State. Researchers use this network, known as the LIGO Data Grid, to analyze the gravitational wave data.
