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…
Accretion Properties and Estimation of Spin of Galactic Black Hole Candidate Swift J1728.9-3613 with NuSTAR during its 2019 outburst
Skye R. Heiland, Arka Chatterjee, Samar Safi-Harb +2
Black hole X-ray binaries (BHXRBs) play a crucial role in understanding the accretion of matter onto a black hole. Here, we focus on exploring the transient BHXRB \source~discovere…
Broadband X-ray Spectroscopy and Estimation of Spin of the Galactic Black Hole Candidate GRS 1758-258
Arghajit Jana, Hsiang-Kuang Chang, Arka Chatterjee +2
We present the results of a broadband (0.5-78 keV) X-ray spectral study of the persistent Galactic black hole X-ray binary GRS 1758-258 observed simultaneously by Swift and NuSTAR.…
Absorption Variability of the Highly Obscured Active Galactic Nucleus NGC 4507
Arghajit Jana, Claudio Ricci, Sachindra Naik +6
We present a detailed study of the highly obscured active galaxy NGC 4507, performed using four Nuclear Spectroscopic Telescope Array (NuSTAR) observations carried out between May…
Broadband X-Ray Observations of the 2018 Outburst of the Changing-Look Active Galactic Nucleus NGC 1566
Arghajit Jana, Neeraj Kumari, Prantik Nandi +5
We study the nature of the changing-look Active Galactic Nucleus NGC 1566 during its June 2018 outburst. During the outburst, the X-ray intensity of the source rises up to ~25-30 t…
