DOI: 10.1093/mnras/stae1711

Abstract: X-ray observations of neutron star (NS) low mass X-ray binaries (LMXBs) are useful to probe physical processes close to the NS and to constrain source parameters. Aql X-1 is a transient NS LMXB which frequently… read more here.

DOI: 10.1093/mnras/stx1970

Abstract: We present a detailed analysis of GRB 151006A, the first gamma-ray burst (GRB) detected by AstroSat Cadmium-Zinc-Telluride Imager (CZTI). We study the long-term spectral evolution by exploiting the ... read more here.

DOI: 10.1093/mnras/stz1704

Abstract: The multiband photon emission and spectral evolution of G54.1+0.3 are investigated in the framework of leptonic and leptonic–hadronic models. We model the spectral energy distribution (SED) of the pulsar wind nebula (PWN) and find that… read more here.

DOI: 10.1093/mnras/stz3217

Abstract: Characterizing the long-term variability of AGNs is a key legacy of RXTE. We carry out a spectral analysis on a sample of 20 Seyfert 1 galaxies, which had been observed by the RXTE for at… read more here.
