CV Vishveshwara, pioneer in black hole research work, passes away
His calculations gave a graphic form to the signals emitted by two merging black holes. This was the waveform detected in 2015 by the LIGO collaboration.
Professor CV Vishveshwara who did pioneering work on black holes, passed away on 16 January 2017 in Bengaluru following a brief illness. He was 77. He is survived by wife and two daughters.

About CV Vishveshwara
• In the 1970s at the University of Maryland, he was among the first to study black holes even before they were named.
• His calculations gave a graphic form to the signals emitted by two merging black holes. This was the waveform detected in 2015 by the LIGO collaboration.
• This waveform also contained the quasi normal modes, a ringdown stage that sounds like a fading out ringing bell.
• In February 2016, he was invited to the synchronised announcement of the first discovery of gravitational waves at IUCAA.
• Vishveshwara also drew cartoons, many of which were published in physics conference proceedings. Spektrum der Wissenschaft, a German magazine, had published many of his cartoons depicting Einstein.
• He was also the founding director of the Jawaharlal Nehru Planetarium in Bengaluru.
• He had written several books including Einstein’s Enigma and Black Holes in My Bubble Bath.
