Relativistic Scattering in the Funnel of Cygnus X-3
Suraj K. Chaurasia, Ranjeev Misra, Amit Pathak
Cygnus X-3 presents significant challenges to standard accretion models. Recent polarimetric observations by IXPE reveal high polarization degrees (PD) in the hard state ($\sim 23\…

Accretion Disk Evolution in GX 339-4 Across Spectral States Using NuSTAR, NICER, and Insight-HXMT Observations
Ruchika Dhaka, Ranjeev Misra, Suraj Kumar Chaurasia
We present a broadband spectral analysis of the black hole X-ray binary GX 339-4 during its 2021 outburst, covering both hard and soft spectral states. Using simultaneous observati…

Spectral Analysis of Cyg X-3 using simultaneous AstroSat and Insight-HXMT Observations
Suraj K. Chaurasia, Gitika Mall, Ruchika Dhaka +2
We present the results from the spectral analysis of Cygnus X-3 using simultaneous data from AstroSat and Insight-HXMT during its soft state. A pure reflection spectrum, including…
