Correlated Short-Timescale Hard-Soft X-ray Variability of the Blazars Mrk 421 and 1ES 1959+650 using $\text{AstroSat}$

Susmita Das, Ritaban Chatterjee

We study simultaneous soft ($0.7-7$ keV) and hard ($7-20$ keV) X-ray light curves at a total of eight epochs during $2016-2019$ of two TeV blazars Mrk 421 and 1ES 1959+650 ob…
