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…
Accretion Flow Properties of EXO 1846-031 During its Multi-Peaked Outburst After Long Quiescence
Sujoy Kumar Nath, Dipak Debnath, Kaushik Chatterjee +3
We study the recent outburst of the black hole candidate EXO 1846-031 which went into an outburst in 2019 after almost 34 years in quiescence. We use archival data from Swift/XRT,…
Study of accretion flows around an ultraluminous X-ray source M82 X-1 using NuSTAR data
Santanu Mondal, Biswaraj Palit, Sandip K. Chakrabarti
We study the spectral properties and accretion flow behavior of an ultraluminous X-ray source M82\,X-1 using {\it NuSTAR} observations. We use the physical two component advective…
Flux and spectral variability of Mrk 421 during its moderate activity state using NuSTAR: Possible accretion disc contribution?
Santanu Mondal, Priyanka Rani, C. S. Stalin +2
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 expec…
Transonic accretion and winds around Pseudo-Kerr black holes and comparison with general relativistic solutions
Abhrajit Bhattacharjee, Sandip K. Chakrabarti, Dipak Debnath
Spectral and timing properties of accretion flows on a black hole depend on their density and temperature distributions, which in turn come from the underlying dynamics. Thus, an a…
Simulation of Cosmic Rays in the Earth's Atmosphere and Interpretation of Observed Counts in an X-ray Detector at Balloon Altitude Near Tropical Region
Ritabrata Sarkar, Abhijit Roy, Sandip K. Chakrabarti
The study of secondary particles produced by the cosmic-ray interaction in the Earth's atmosphere is very crucial as these particles mainly constitute the background counts produce…
