S190814bv

S190814bv was an event in which gravitational waves were measured. The event, which was recorded on August 14, 2019 by LIGO and VIRGO , represented a union of two astronomical objects. At least one of the objects had a mass that fit into the mass gap . The mass gap is the range between the minimum mass of a black hole at five solar masses and the maximum mass of a neutron star at three solar masses. It is nevertheless assumed that this recorded gravitational wave is a union of a black hole with a neutron star. After measuring the signal, the sky was searched for electromagnetic radiation, however, contrary to expectations, the researchers found no evidence that this event would emit radiation.
