However, in early 2018, it dimmed significantly and has stayed in this faint state ever since. We report on AstroSat observation of GRS 1915+105 in its unusual low/hard state during May 15-16 2019. We performed time-resolved spectroscopy of sporadic X-ray flares observed in this state and found that the spectra can be fitted well either with high absorption or by relativistic reflection models. Our reflection dominated spectra is very similar to that of reflection dominated spectra of AGN’s in low flux state. |
