Ramesh Narayan (born in Mumbai, India, in 1950) is an Indian-American theoretical astrophysicist, currently the Thomas Dudley Cabot Professor of the Natural Sciences in the Department of Astronomy at Harvard University. Full member of the National Academy of Sciences,[1] Ramesh Narayan is widely known for his contributions on the theory of black hole accretion processes. Recently he is involved in the Event Horizon Telescope project,[2] which led in 2019 to the first image of the event horizon of a black hole.[3][4][5]

Education and career path

Ramesh Narayan received a B.Sc. in Physics from Madras University and a Ph.D. from Bangalore University in 1979.[1] After his studies, he spent several years as a postdoctoral researcher at the Raman Research Institute in Bangalore. Later on, he moved to the California Institute of Technology (Caltech) in 1983, where he eventually became a senior research fellow. After a few years as a faculty member at the University of Arizona, he moved to Harvard University in 1991 as a professor, where he is currently the Thomas Dudley Cabot Professor of Natural Sciences at the Astronomy Department.[6] He also served on the Physical Sciences jury for the Infosys Prize from 2011 to 2014.[7]

Fellowships

Ramesh Narayan is currently a member of the United States National Academy of Sciences,[1] a fellow of the Royal Society of London, a fellow of the American Association for the Advancement of Science and a fellow of the World Academy of Sciences.[6]

Scientific contributions

Ramesh Narayan is widely known for his broad contributions to theoretical astrophysics, specifically to

supermassive black holes and the possibility of forming jets, via the Blandford–Znajek process. He significantly improved GRRMHD codes to perform numerical simulations, which handle General Relativistic (GR), Radiative (R), Magneto (M) hydrodynamical (HD) physics.[13]
