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…
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…
Time resolved spectroscopy of a GRS 1915+105 flare during its unusual low state using AstroSat
Sajad Boked, Bari Maqbool, V. Jithesh +3
Since its discovery in 1992, GRS 1915+105 has been among the brightest sources in the X-ray sky. However, in early 2018, it dimmed significantly and has stayed in this faint state…
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…
