AstroSat and Chandra view of the high soft state of 4U 1630-47 (4U 1630-472): evidence of the disk wind and a rapidly spinning black hole
Mayukh Pahari, Sudip Bhattacharyya, A R Rao +8
We present the X-ray spectral and timing analysis of the transient black hole X-ray binary 4U 1630-47, observed with the AstroSat, Chandra and MAXI space missions during its soft X…
AstroSat-CZTI detection of variable prompt emission polarization in GRB 171010A
Vikas Chand, Tanmoy Chattopadhyay, Gor Oganesyan +5
We present spectro-polarimetric analysis of \thisgrb\ using data from \asat, \fermi, and \swift, to provide insights into the physical mechanisms of the prompt radiation and the je…
Violation of synchrotron line of death by the highly polarized
Vikas Chand, Tanmoy Chattopadhyay, S. Iyyani +7
is one of the brightest gamma-ray bursts (GRBs) observed with Gamma-ray Burst Monitor (GBM) in the energy range of keV, while at the same time it…
Timing Offset Calibration of CZTI instrument aboard ASTROSAT
Avishek Basu, Bhal Chandra Joshi, Dipankar Bhattacharya +10
The radio as well as the high energy emission mechanism in pulsars is yet not understood properly. A multi-wavelength study is likely to help in better understanding of such proces…
Magnetar Signature - The U Curve
Vikram Soni, Dipankar Bhattacharya, Sameer Patel +2
This work looks at some definitive signatures of magnetars, in particular of period closures accompanied by a decline of X-ray radiation in two models. We review some of the previo…
