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…
Iron Fluorescence in X-class Solar Flares: Aditya-L1/SoLEXS Observations
Abhilash R. Sarwade, K. Sankarasubramanian, Monoj Bug +5
Iron fluorescence is produced by the irradiation of the solar photosphere by coronal X-rays during flares. This study presents the first comprehensive analysis of iron K fluores…

The Solar Low-Energy X-ray Spectrometer (SoLEXS) on board India's Aditya-L1 mission was launched on 2 September 2023 and commenced solar observations on 13 December 2023 following…
Probing the accretion geometry of black hole X-ray binaries: A multi-mission spectro-polarimetric and timing study
Seshadri Majumder, Ankur Kushwaha, Swapnil Singh +3
We present a comprehensive spectro-polarimetric and timing analysis of twelve black hole X-ray binaries, namely Cyg X-1, 4U 1630-47, Cyg X-3, LMC X-1, 4U 1957+115, LMC X-3, Swift J…
First detection of X-ray polarization in thermal state of LMC X-3: Spectro-polarimetric study with IXPE
Seshadri Majumder, Ankur Kushwaha, Santabrata Das +1
We report a comprehensive spectro-polarimetric study of the black hole binary LMC X using simultaneous {\it IXPE}, {\it NICER} and {\it NuSTAR} observations in 0.520 keV ene…
Spectro-polarimetry of 4U 1957+115 with IXPE: Effects of spin and returning radiation on polarised emission of black hole in thermal state
Ankur Kushwaha, Kiran M. Jayasurya, Anuj Nandi
We present a comprehensive spectro-polarimetric study of persistent Black hole X-ray binary 4U with {\it IXPE} and {\it NICER} observations. The source is observed i…
IXPE and NICER view of Black hole X-ray binary 4U 1630-47: First significant detection of polarized emission in thermal state
