India loses its pioneer in black hole research work

  • Professor C.V. Vishveshwara, who did pioneering work on black holes, passed away.
  • In the 1970s, while at the University of Maryland, he was among the first to study “black holes” even before they had been so named.
  • His calculations gave a graphic 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 contained the so-called “quasi normal modes” – a ringdown stage that sounds like a bell’s ringing sound that is fading out.
  • Prof. Vishveshwara was the founding director of the Jawaharlal Nehru Planetarium in Bengaluru.
  • He has written several books including Einstein’s Enigma, or Black Holes in My Bubble Bath.
