Spectral States of OJ 287 blazar from Multi-wavelength Observations with
K. P. Singh, P. Kushwaha, A. Sinha +3
We present {\it 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 NuST…
Complex optical/UV and X-ray variability in Seyfert 1 galaxy Mrk 509
Neeraj Kumari, Main Pal, Sachindra Naik +3
We performed a detailed spectral and timing analysis of a Seyfert 1 galaxy Mrk 509 using data from the Neil Gehrels Swift observatory that spanned over ~13 years between 2006 and 2…
AstroSat View of Blazar OJ 287: A complete evolutionary cycle of HBL Component from end-phase to disappearance and Re-emergence
Pankaj Kushwaha, K. P. Singh, A. Sinha +3
We report three AstroSat observations of BL Lacertae object OJ 287. The three observations caught it in very different flux states that are connected to different broadband spectra…
Spectro-Timing Analysis of a highly variable narrow-line Seyfert 1 galaxy NGC 4748 with AstroSat and XMM-Newton
Main Pal, Neeraj Kumari, Pankaj Kushwaha +8
We present a detailed timing and spectral study of an extremely variable narrow-line Seyfert~1 galaxy NGC 4748 using observations in the year 2017 and 2014 performed with AstroSat…
