Tracing the outburst decay of soft X-ray transients Aql X-1 and 4U 1608-52 with XSPECT
Rwitika Chatterjee, Vivek Kumar Agrawal, V. P. Shyam Prakash +2
XSPECT instrument on-board XPoSat mission is a soft X-ray spectrometer sensitive in the energy band 0.815 keV. XSPECT has observed several bright neutron star low mass X-ray bin…
Multiwavelength study of radio galaxy Pictor A: detection of western hotspot in far-UV and possible origin of high energy emissions
Sanna Gulati, Debbijoy Bhattacharya, M. C. Ramadevi +2
A comprehensive study of the nucleus and western hotspot of Pictor A is carried out using AstroSat observations, 13 years of Fermi, and archival Swift observations, along with othe…
IXPE and NICER view of Black hole X-ray binary 4U 1630-47: First significant detection of polarized emission in thermal state
Ankur Kushwaha, Kiran M. Jayasurya, Vivek K. Agrawal +1
We present a detailed spectro-polarimetric study of Black hole X-ray binary 4U during its outburst with IXPE and NICER observations. The source is observed in disk…
Detection of significant X-ray polarization from transient NS-LMXB XTE J1701-462 with IXPE and its implication on the coronal geometry
Kiran M. Jayasurya, Vivek K. Agrawal, Rwitika Chatterjee
In this paper, we performed a spectro-polarimetric analysis of the transient NS-LMXB XTE J1701-462 using IXPE, NICER, and NuSTAR data during its 2022 outburst. We report the signif…
Swift J1753.5-0127 : Understanding the accretion geometry through frequency resolved spectroscopy
Blessy E. Baby, Ramadevi M. C
The Black Hole Binary source Swift J175.5-0127 remained in outburst for 12 years from May 2005 to April 2017. For most part of the outburst, the source remained in the Low H…
Revealing the nature of the transient source MAXI J0637-430 through spectro-temporal analysis
Blessy E. Baby, Bhuvana G. R., Radhika D. +3
We study the spectral and temporal properties of MAXI J0637-430 during its 2019-2020 outburst using \textit{NICER}, \textit{AstroSat} and \textit{Swift-XRT} data. The source was in…
