Investigating the Anti-Correlation between Photon Index and Flux of the Crab using RXTE and NuSTAR
Debjit Chatterjee, Hsiang-Kuang Chang, Dipak Debnath +2
We present a systematic study of the recently reported anti-correlation between X-ray flux and photon index () in the Crab Nebula, using archival RXTE/PCA (3 - 50 keV), RXTE/HEX…
NGC 7314: X-ray Study of the Evolving Accretion Properties
Debjit Chatterjee, Arghajit Jana, A. Mangalam +1
We present a comprehensive analysis of the timing and spectral properties of NGC 7314, a Seyfert 1.9 galaxy, using X-ray observations from {\it XMM-Newton}, {\it NuSTAR}, and {\it…
Detection of QPO Soft Lag during Outburst of Swift J1727.8-1613: Estimation of Instrinsic Parameters from Spectral Study
Dipak Debnath, Sujoy Kumar Nath, Debjit Chatterjee +2
The recently discovered bright transient black hole candidate Swift J1727.8-1613 is studied in a broad energy range ( keV) using combined NICER and NuSTAR data on 29 August…
Accretion properties of soft X-ray transient XTE J1856+053 during its 2023 Outburst
Debjit Chatterjee, Arghajit Jana, Hsiang-Kuang Chang
Soft X-ray transients are a subclass of the low mass X-ray binaries that occasionally show a sudden rise in their soft X-ray luminosity; otherwise, they remain in an extremely fain…
Spectral Properties of GX~339--4 in the Intermediate State Using AstroSat Observation
Arghajit Jana, Debjit Chatterjee, Hsiang-Kuang Chang +2
We present the results obtained from the spectral studies of black hole X-ray binary GX~339--4 using \astrosat~ observations during its 2021 outburst. \astrosat~ observed the sourc…
Evolution of low frequency quasi-periodic oscillations in GX 339-4 during its 2021 outburst using AstroSat data
Santanu Mondal, Anirudh Salgundi, Debjit Chatterjee +3
The black hole X-ray binary GX\,339-4 showed an X-ray outburst during 2021. The {\it AstroSat} captured this outburst when the source entered into the intermediate flux state while…
