Observation of gravitational waves from a binary black hole merger.

GW170814: A three - detector observation of gravitational waves from a binary black hole coalescence.

The research paper, «GW151226: Observation of Gravitational Waves from a 22 Solar - mass Binary Black Hole Coalescence,» by the LIGO Scientific Collaboration and the Virgo Collaboration, has been accepted for publication in the journal Physical Review Letters.

Findings from this and two previous discoveries of black hole mergers are providing the WSU scientists and colleagues at the Laser Interferometer Gravitational - Wave Observatory (LIGO) an unprecedented glimpse into the early universe and shedding new light on how binary black holes form.

The group in which he works is involved in the instrumental development for the LISA PathFinder mission (ESA), a technology precursor mission for a future space - based gravitational - wave observatory, LISA, which will detect the gravitational radiation from low frequency sources like massive black hole mergers, inspiraling stellar compact objects into massive black holes, and galactic binaries.

Astronomers have combined data from NASA's Chandra X-ray Observatory, the Hubble Space Telescope and the National Science Foundation's Karl G. Jansky Very Large Array (VLA) to conclude that a peculiar source of radio waves thought to be a distant galaxy is actually a nearby binary star system containing a low - mass star and a black hole.

For example, if a black hole is a member of a binary star system, matter flowing into it from its companion becomes intensely heated and then radiates X-rays copiously before entering the event horizon of the black hole and disappearing forever.
