Flux Dependence of the 1\,keV Soft X-ray Feature in SAX J1808.4-3658 with \textit{NICER}
Katherine Bruce, Anne M. Lohfink, Jaiverdhan Chauhan +3
We present a systematic X-ray spectral analysis of the 2019 and 2022 outbursts of the accreting millisecond pulsar SAX J1808.4-3658 with extit{NICER} with a particular emphasis on…
Comparative spectro-temporal study between 1A 1246588 and 4U 0614091 using AstroSat
Suchismito Chattopadhyay, Soma Mandal, Ranjeev Misra
We present a comparative broadband spectro-temporal study of the ultra-compact X-ray binary (UCXB) candidates 1A 1246588 and 4U 0614091 using AstroSat observations. Spectral…
Spectral evolution of NS binary system GX 349+2 using AstroSat observations
Garima Tyagi, Suchismito Chattopadhyay, Sree Bhattacherjee +3
We present a broadband spectral study of the Sco-like Z source GX 349+2 using AstroSat LAXPC and SXT observations obtained during 2019 and 2024. The X-ray light curves exhibit larg…
Importance and Science Outcomes from the first XSPECT/XPoSat Workshop
Anuj Nandi, Rwitika Chatterjee, V. P. Shyam Prakash +49
This paper summarizes the science outcomes of the first Workshop on Data Analysis using observations from the XSPECT payload onboard the XPoSat, which brought together early-career…
QPO signatures of disk restoration after type-I X-ray bursts from 4U~1636536
Suchismito Chattopadhyay, Jaiverdhan Chauhan, Ranjeev Misra +4
Type--I thermonuclear bursts (TNBs) from neutron star low-mass X-ray binaries (NS LMXBs) originate on the neutron star's surface from the unstable burning of the accreted material.…
Spectral-timing analysis of the kilohertz quasi-periodic oscillations and constraints on the mass of the neutron star in 4U 1636-536 using AstroSat observations
Suchismito Chattopadhyay, Soma Mandal, Ranjeev Misra
Kilohertz quasi-periodic oscillations (kHz QPOs) are believed to originate from the orbital timescales of the inner accretion flow, reflecting the dynamics of the innermost disk re…
Spectro-temporal evolution of 4U 1702-429 using AstroSat-NICER
Suchismito Chattopadhyay, Ranjeev Misra, Soma Mandal +2
We present the broadband spectral and timing properties of the atoll source 4U 1702-429 using two observations of AstroSat with the second one having simultaneous NICER data. For b…
X-Ray spectral and temporal properties of LMXB 4U 1608-52- observed with AstroSat and NICER
Sree Bhattacherjee, Ankur Nath, Biplob Sarkar +4
We report results from a detailed study of the neutron star X-ray binary, 4U 1608-52 using observations with {\it AstroSat} (LAXPC/SXT) and {\it NICER} during its 2016 and 2020 out…
Spectral and Timing evolution of GX 340+0 along its Z-track
Suchismito Chattopadhyay, Yashpal Bhulla, Ranjeev Misra +1
We present the results from spectral and timing study of the Z source GX 340+0 using AstroSat's SXT and LAXPC data. During the observation the source traced out the complete Z-trac…
