Investigating Changing-Look Active Galactic Nuclei with Long-term Optical and X-Ray Observations
A. Jana, C. Ricci, M. J. Temple +7
Changing-look active galactic nuclei (CLAGNs) show the appearance and disappearance of broad emission lines in their UV/optical spectra on timescales of months to decades. Here, we…
Accretion properties of soft X-ray transient XTE J1856+053 during its 2023 Outburst
Debjit Chatterjee, Arghajit Jana, Hsiang-Kuang Chang
Soft X-ray transients are a subclass of the low mass X-ray binaries that occasionally show a sudden rise in their soft X-ray luminosity; otherwise, they remain in an extremely fain…
Long-term X-ray temporal and spectral study of a Seyfert galaxy Mrk 6
Narendranath Layek, Prantik Nandi, Sachindra Naik +3
We present a long-term X-ray study of a nearby Active Galactic Nucleus Mrk 6, utilizing observations from XMM-Newton, Suzaku, Swift and NuSTAR observatories, spanning 22 years from…
Spectral Properties of GX~339--4 in the Intermediate State Using AstroSat Observation
Arghajit Jana, Debjit Chatterjee, Hsiang-Kuang Chang +2
We present the results obtained from the spectral studies of black hole X-ray binary GX~339--4 using \astrosat~ observations during its 2021 outburst. \astrosat~ observed the sourc…
Survey of Bare Active Galactic Nuclei in the local universe (z < 0.2): I. On the origin of Soft-Excess
Prantik Nandi, Arka Chatterjee, Arghajit Jana +5
We analyse a sample of 21 `bare' Seyfert~1 Active Galactic Nuclei (AGNs), a sub-class of Seyfert~1s, with intrinsic absorption , in t…
Coronal Properties of Low-Accreting AGNs using Swift, XMM-Newton and NuSTAR Observations
Arghajit Jana, Arka Chatterjee, Hsiang-Kuang Chang +6
We studied the broadband X-ray spectra of {\it Swift}/BAT selected low-accreting AGNs using the observations from {\it XMM-Newton}, {\it Swift}, and {\it NuSTAR} in the energy rang…
