Ramesh Narayan (astrophysicist)

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.

He wrote landmark studies on gamma-ray bursts,[8] accretion disks,[9] black holes,[10] gravitational lensing[11] and neutron stars.

[12] He is well known for his works on numerical simulations on accretion flows around 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), and MagnetoHydroDynamic (MHD) physics.
