Black hole collision.

Sukanta Bose

Dr. Sukanta Bose is interested in problems in relativistic astrophysics and cosmology that can benefit from insights drawn from the emerging field of gravitational wave (GW) astronomy, often combined with associated electromagnetic and particle signals. He is a member of the LIGO Scientific Collaboration and was a Project Coordinator of the LIGO-India project. His research currently focuses on:

  • Understanding how black holes respond to tidal perturbations, such as due to an orbiting companion
  • Characterizing one of the densest forms of stable matter in the universe — as found in neutron stars
  • Measuring the Hubble parameter with gravitational-wave observations
  • Understanding noise transients in the strain of current GW detectors and troubleshooting their origins
  • Testing Einstein’s theory of gravity — General Relativity.
