Is the Spin of the Black Hole in GX 339-4 Negative?
Andrzej A. Zdziarski, Srimanta Banerjee, Michal Szanecki +2
We have studied the accreting black hole binary GX 339--4 using two highly accurate broad-band X-ray data sets in very soft spectral states from simultaneous NICER and NuSTAR obser…
A multi-wavelength study of the hard and soft states of MAXI J1820+070 during its 2018 outburst
Srimanta Banerjee, Gulab C. Dewangan, Christian Knigge +8
We present a comprehensive multi-wavelength spectral analysis of the black hole X-ray binary MAXI J1820+070 during its 2018 outburst, utilizing AstroSat far UV, soft and hard X-ray…
What Is the Black Hole Spin in Cyg X-1?
Andrzej A. Zdziarski, Swadesh Chand, Srimanta Banerjee +6
We perform a detailed study of the black hole spin of Cyg X-1, using accurate broad-band X-ray data obtained in the soft spectral state by simultaneous NICER and NuSTAR observation…
Probing the accretion geometry of the atoll source 4U 1702-429 in different spectral states with NICER, NuSTAR, and AstroSat
Srimanta Banerjee, Jeroen Homan
We perform a comprehensive spectral study of a carefully selected sample (total exposure ks) of NICER observations of the atoll neutron star low-mass X-ray binary 4U 17…
