ANSWER: Professor C.V. Vishveshwara
Prof. Vishveshwara who did pioneering work on black holes, passed away on Jan 16th 2017 after a period of illness.
He was nearing 78 years.
In the 1970s, while at University of Maryland, he was among the first to study “black holes” even before they had been so named.
His calculations succeeded in giving a graphical form to the signal that would be emitted by two merging black holes.
This was the waveform detected in 2015 by the LIGO collaboration, and contain the so-called quasi normal modes.
The modes are a ringdown stage that sounds like a bell’s ringing sound that is fading out.
