Hilo astronomer helps size up the first black hole ever detected
A Hilo-based astronomer has joined a team that’s rewriting everything we know about the massive black hole Cygnus X-1.
Alex Tetarenko, who works at the James Clerk Maxwell Telescope (JCMT), has been collaborating with an international team of researchers to analyze new observations of the first black hole ever detected, Cygnus X-1. Their research shows that the system contains the most massive stellar-mass black hole ever detected without the use of gravitational waves.
