Still image from a numerical simulation of two black holes that inspiral and merge, emitting gravitational waves. The black holes have large and nearly equal masses, with one only 3% more massive than the other. The simulated gravitational wave signal is consistent with the GW190521 observation made by the LIGO and Virgo. (Credit: N. Fischer, H. Pfeiffer, A.

Researchers from Missouri S&T’s Institute for Multi-messenger Astrophysics and Cosmology are among a team of international scientists who participated in the detection of a signal from the most massive black hole merger yet observed in gravitational waves.
The S&T researchers include:
The event observed by the LIGO Scientific Collaboration and the Virgo Collaboration produced the first clear detection of a black hole with a mass between 100 and 1,000 times that of the sun. It is labeled GW190521.
The S&T researchers are listed among the authors in the discovery papers published in Physical Review Letters and The Astrophysical Journal Letters.
