Dr Poshak Gandhi

Academic Staff

Dr. Poshak Gandhi researches extreme time-domain astrophysics, with an emphasis on multiwavelength observations of black holes. His studies have established the connection between accretion and extreme obscuration in supermassive black holes at the centres of massive galaxies, as well as the causal links between accretion and outflows in relativistic astrophysical jets.

Dr. Gandhi hails from New Delhi, and has worked in Chile (ESO) and Japan (RIKEN/JAXA). He completed his thesis in X-ray astronomy from the Institute of Astronomy (Univ. of Cambridge), but has recently focused on connecting the high-energy regime with infrared and optical observations. He is a member of the NuSTAR and Hitomi science teams. Several of his projects are focused on big data time-domain mining and analysis, including LSST, NuSTAR and AstroSat; he is the PI (or affiliate PI) for major observational projects in each of these, and offers PhD projects in all. More details about his research are on his personal homepage and he may be reached through twitter:
