Accretion Geometry of the New Galactic Black Hole Candidate AT2019wey in the Hard State
Pragati Sahu, Swadesh Chand, Gulab C. Dewangan +3
We perform broadband spectral and timing studies of the Galactic low-mass black hole candidate AT2019wey using quasi-simultaneous NICER, Swift, and NuSTAR observations obtained in…
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.…
XSPECT on-board XPoSat: Calibration and First Results
Rwitika Chatterjee, Koushal Vadodariya, Radhakrishna Vatedka +6
XPoSat is India's first X-ray spectro-polarimetry mission, consisting of two co-aligned instruments, a polarimeter (POLIX) and a spectrometer (XSPECT), to study the X-ray emission…
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…
First spectro-polarimetric study of the neutron star low-mass X-ray binary GX 9+1
V. P. Shyam Prakash, Vivek K. Agrawal, A. M. Vinodkumar
We present the first spectro-polarimetric study of the bright atoll source GX 9+1, using the simultaneous Imaging X-ray Polarimetry Explorer (IXPE), and Neutron star Interior Compo…
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…
