Evidence of oscillating `compact' Comptonized corona in GRS 1915+105: Insights into HFQPOs with AstroSat
Sreehari Harikesh, Seshadri Majumder, Santabrata Das +1
We present, for the first time, an in-depth dynamical analysis of the spectro-temporal properties of the soft variability classes (, , , and ) of GRS 1915+105 durin…
