Radio Dichotomy in Quasars with H FWHM greater than km\,s
A. Chakraborty, A. Bhattacharjee, M. S. Brotherton +3
It has been inferred from large unbiased samples that - of all quasars are radio-loud (RL). Using the quasar catalog from the Sloan Digital Sky Survey, we show that the…
Two-Component Advective Flows around Neutron Stars
Ayan Bhattacharjee, Sandip K. Chakrabarti
The fundamental difference between accretion around black holes and neutron stars is the inner boundary condition, which affects the behavior of matter very close to the compact ob…
Similarities and Differences in Accretion Flow Properties between GRS 1915+105 and IGR J17091-3624: a Case Study
Anuvab Banerjee, Ayan Bhattacharjee, Dipak Debnath +1
We perform a comparative spectro-temporal analysis on the variability classes of GRS 1915+105 and IGR J17091-3624 to draw inferences regarding the underlying accretion flow mechani…
A Unified Spectral Model for Accreting Neutron Stars
Ayan Bhattacharjee, Sandip K. Chakrabarti
Recent studies show that accretion flows around weakly magnetic Neutron Stars undergo multiple shocks, before reaching the surface of the star, which contribute to the spectral and…
Accretion Flow Properties of GRS 1915+105 During Its Class Using AstroSat Data
Anuvab Banerjee, Ayan Bhattacharjee, Debjit Chatterjee +4
The Galactic microquasar GRS 1915+105 shows rich variability which is categorized into different classes. In this paper, we report temporal and spectral analysis of GRS 1915+105 to…
AstroSat Observation of Non-Resonant Type-C QPOs in MAXI J1535-571
D. Chatterjee, D. Debnath, A. Jana +8
Galactic transient black hole candidate (BHC) MAXI J1535-571 was discovered on 2017 September 02 simultaneously by {\it MAXI}/GSC and {\it Swift}/BAT instruments. It has also been…
