General Relativity and Gravitational Waves

Prof. Sanjeev Dhurandhar has published over hundred papers in top international journals such as Physical Reviews, MNRAS, Classical & Quantum Gravity, and also a review article (co-authored with M. Tinto) in Living Reviews published by Springer. About three quarters of the publications are on gravitational waves, mainly on their data analysis, and the rest are on various aspects of general relativity. The author led the gravitational wave group at IUCAA from 1989 to 2011 until he superannuated. He has taught general relativity since 1987 in the Physics Department, Pune University, several times to master's students. Short versions of the course including gravitational waves were taught in IUCAA workshops/schools and also independently in universities around India. He is a member of the LIGO Science Collaboration (LSC) for the past two decades. The author is a recipient of several prestigious awards which include the Vijnan Bhushan Firodia Award for Outstanding Contributions to Science, the Meghnad Saha Memorial Gold Medal (The Asiatic Society, Kolkata, India) for Outstanding Contributions to Physics, Milners breakthrough prize (Milners Foundation U.S.A.) awarded for the detection of gravitational waves (shared with the LSC), etc. He is a fellow of the American Physical Society (APS), the Indian Academy of Sciences, Bangalore, and National Academy of Sciences India, Allahabad, as well as of the Indian National Science Academy (INSA), Delhi. He has had collaborations with most of the leading detector groups in the world which include: the LIGO Lab, Caltech, USA; Albert Einstein Institute, Max Planck, Potsdam and Hannover, Germany; NAO & Osaka University, Japan; Virgo; Nice Observatory, Nice, France; and University of Western Australia, Perth, Australia. Prof. Sanjit Mitra has been involved in gravitational wave research for twenty years. He has taught the general relativity course for M.Sc. and Ph.D. students for nearly ten years and given lectures on gravitational waves in several works. He has authored thirty research papers in reputed journals and is an author in more than two hundred papers by the LIGO Scientific Collaboration and also the Planck Collaboration for his research on cosmic microwave background. The author is a recipient of several prestigious awards which include the 2019 Giuseppe and Vanna Cocconi Prize awarded to the WMAP & Planck Collaborations by EPS, the 2018 Gruber Cosmology Prize for mapping the CMB anisotropies as part of the Planck Team, the Faculty Research Awards 2018 by Careers 360, the 2017 Princess of Asturias Award for Technical and Scientific Research as part of the LIGO Scientific Collaboration (LSC), a 2016 Special Breakthrough Prize in Fundamental Physics for the detection of gravitational waves as part of the LIGO Scientific Collaboration, the 2016 Gruber Cosmology Prize for the detection of gravitational waves as part of the LSC, the 2011 JPL-NASA Team STAR Award for outstanding contribution to Planck, the 2007 LIGO thesis prize - Honorary mention.

"There is ... much to like, in particular the way in which the mathematics is motivated by the underlying physics. It will make a good addition to a gravitational-wave physicist's shelf." (Jonathan Gair, The Observatory, Vol. 143 (1292), February, 2023)
