Quiet, but not silent: Uncovering quiescent state properties of two transient High Mass X-ray binaries
Gayathri Raman, Varun, Pragati Pradhan +1
We present the first set of broadband spectral and timing studies of two transient X-ray pulsars, MXB 0656-072 and MAXI J1409-619 using NuSTAR observations conducted during quiesce…
NuSTAR investigation of X-ray variability and hard X-ray spectral properties in IGR J16320-4751 and IGR J16479-4514
Varun, Gayathri Raman
We present the results obtained from a comprehensive timing and spectral study of two high-mass X-ray binary sources using NuSTAR observations. These two sources, IGR J16320-4751 a…
Timing and spectral studies of Cen X-3 in multiple luminosity states using
Ritesh Bachhar, Gayathri Raman, Varun Bhalerao +1
We present the results of timing and spectral analysis of the HMXB pulsar, Cen X-3, with the help of observations carried out using the Large Area X-ray Proportional Counter (LAXPC…
AstroSat detection of a mHz QPO and cyclotron line in IGR J19294+1816 during the 2019 outburst
Gayathri Raman, Varun, Biswajit Paul +1
We present results from timing and spectral analysis of the HMXB X-ray pulsar IGR J19294+1816 observed using \asr during its recent Type-I outburst in October, 2019. AstroSat obser…
A comprehensive study of 2019-2020 flare of OJ 287 using AstroSat, Swift, and NuSTAR
Raj Prince, Gayathri Raman, Rukaiya Khatoon +5
OJ 287 is a well-studied binary black hole system, that occasionally exhibits bright X-ray and optical flares. Here we present a detailed spectral study of its second brightest X-r…
Thermonuclear X-ray bursts detected in Cyg X-2 using AstroSat/LAXPC
Jincy Devasia, Gayathri Raman, Biswajit Paul
We report the detection of 5 Type-1 thermonuclear X-ray bursts and one burst-like event in the neutron star LMXB source, Cyg X-2 using X-ray data obtained with the Large Area X-ray…
