The LIGO collaboration announced a ‘super-event’ alert on its GraceDB (Gravitational Wave Candidate Event Database). The event, dubbed S190814bv, after the date of its discovery, has sent waves of excitement through the astrophysics community because it is different from previous events observed so far.
Black holes are a critical part of the formation and evolution of galaxies and new radio telescopes will be needed for us to learn how black holes interact with stars and galaxies. Results are important for astronomy because they potentially impact how we understand galaxy evolution.
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool.
A black hole is a region of space-time exhibiting gravitational acceleration so strong that no particles or even electromagnetic radiation such as light can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform space time to form a black hole.
