The first detection of X-ray polarization in a newly discovered Galactic transient Swift\,J151857.0-572147
Santanu Mondal, S. Pujitha Suribhatla, Kaushik Chatterjee +2
We study the spectro-polarimetric properties of a newly discovered black hole X-ray binary Swift\,J151857.0-572147 jointly using {\it IXPE} and {\it NuSTAR} observations during Mar…
Spectral nature of Sco X-1 observed using the X-ray SPECtroscopy and Timing (XSPECT) payload on-board XPoSat
V. P. Shyam Prakash, Vivek K. Agrawal, Rwitika Chatterjee +3
Scorpius X-1 is the brightest and first discovered X-ray source in the sky. Studying this source in the low-energy band has been challenging in the past due to its high brightness.…
X-Ray spectroscopy and timing (XSPECT) experiment on XPoSat -- instrument configuration and science prospects
Radhakrishna V, Anurag Tyagi, Koushal Vadodariya +11
X-ray Polarimeter Satellite (XPoSat) with POLarimeter Instrument in X-rays (POLIX), is India's first spacecraft dedicated to study medium energy X-ray polarisation from celestial o…
Simultaneous X-ray and optical polarization observations of the blazar Mrk 421
Athira M. Bharathan, C. S. Stalin, S. Sahayanathan +7
We present near-simultaneous X-ray and optical polarization measurements in the high synchrotron peaked (HSP) blazar Mrk 421. The X-ray polarimetric observations were carried out u…
Detection of X-ray Polarization in the High Synchrotron Peaked Blazar 1ES 1959+650
Athira M. Bharathan, C. S. Stalin, Rwitika Chatterjee +4
We report the measurement of X-ray polarization in the high synchrotron peaked blazar 1ES 1959+650. Of the four epochsof observations from the {\it Imaging X-ray Polarimetry Explor…
X-ray polarization observations of IC 4329A with IXPE: Constraining the geometry of the X-ray corona
Indrani Pal, C. S. Stalin, Rwitika Chatterjee +1
X-ray polarimetry is a powerful tool to probe the geometry of the hot X-ray corona in active galactic nuclei (AGN). Here, we present our results on the characterisation of the X-ra…
