X-Ray Timing Properties of the Black Hole Candidate IGR J17091-3624 During the 2022 Outburst Onset with AstroSat
Sree Bhattacherjee, Biplob Sarkar
The paper analyzes rapid X‑ray timing variability of the black‑hole candidate IGR J17091‑3624 during the early phase of its 2022 outburst using AstroSat, focusing on the evolution…
The Polarized X-ray Universe: Insights and Discoveries
Arbind Pradhan, Sree Bhattacherjee, Biplob Sarkar
Polarization is one of the fundamental natures of electromagnetic radiation. The detection of polarization or polarized photons from distant X-ray radiating systems (such as X-ray…
Energy-dependent temporal study of GX 13+1 with AstroSat observation
Arbind Pradhan, Sree Bhattacherjee, Biplob Sarkar
In this work, we performed an energy-dependent study of low-frequency oscillations observed in GX 13+1 using \textit{AstroSat} (Large Area X-ray Proportional Counter and Soft X-ray…
Spectral evolution of GX 17+2 using AstroSat and NICER observations
Sree Bhattacherjee, Ranjeev Misra, Biplob Sarkar +3
We study the spectral evolution of the Z-track source GX 17+2 using AstroSat and NICER observations taken between 2016 and 2020. The AstroSat observations cover the period when the…
