Flux and spectral variability of Mrk 421 during its moderate activity state using NuSTAR: Possible accretion disc contribution?

Mondal, S.; Rani, P.; Stalin, C. S.; Chakrabarti, S. K.; Rakshit, S. (Astronomy & Astrophysics, 2022-06)

The X-ray emission in BL Lac objects is believed to be dominated by synchrotron emission from their relativistic jets. However, when the jet emission is not strong, one could expect signatures of X-ray emission from inverse ...
Spectral States of OJ 287 blazar from Multiwavelength Observations with AstroSat

Singh, K. P.,et.al.; Kushwaha, P. (Monthly Notices of the Royal Astronomical Society, 2022-01)

We present AstroSat soft X-ray, near-UV (NUV), and far-UV (FUV) observations of a blazar, OJ 287, carried out in 2017, 2018, and 2020. The simultaneous observations with NuSTAR in 2017 provide a broad-band look encompassing ...
