Evidence of Heavy Obscuration in the Low-Luminosity AGN NGC 4941
Arghajit Jana, Sachindra Naik, Neeraj Kumari
We present the results obtained from timing and spectral studies of the highly obscured low luminosity active galactic nucleus NGC~4941 using data obtained from the {\it Nuclear Sp…
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…
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…
NICER observations of the black hole candidate MAXI J0637430 during the 2019-2020 Outburst
Arghajit Jana, Gaurava K. Jaisawal, Sachindra Naik +5
We present detailed timing and spectral studies of the black hole candidate MAXI J0637430 during its 2019-2020 outburst using observations with the {\em Neutron Star Interior Co…
Accretion Properties of MAXI J1813-095 during its Failed Outburst in 2018
Arghajit Jana, Gaurava K. Jaisawal, Sachindra Naik +7
We present the results obtained from detailed timing and spectral studies of a black hole candidate MAXI~J1813-095 using {\it Swift}, {\it NICER}, and {\it NuSTAR} observations dur…
Short-Timescale Variability of the Blazar Mrk 421 from AstroSat and Simultaneous Multi-Wavelength Observations
Ritaban Chatterjee, Susmita Das, Archishman Khasnovis +13
We study the multi-wavelength variability of the blazar Mrk 421 at minutes to days timescales using simultaneous data at -rays from Fermi, 0.7-20 keV energies from AstroSat, and…
