The Cadmium Zinc Telluride (CZT) Imager onboard AstroSat, consists of pixelated CZT detectors, which are sensitive to hard X-rays above 20 keV. The individual pixels are triggered by ionising events occurring in them, and the detectors operate in a s

The luminosity function of short Gamma Ray Bursts (GRBs) is modelled by using the available catalogue data of all short GRBs (sGRBs) detected till October, 2017. The luminosities are estimated via the `pseudo-redshifts' obtained from the `Yonetoku co

I have used a sample of long Gamma Ray Bursts (GRBs) common to both \emph{Swift} and \emph{Fermi} to re-derive the parameters of the Yonetoku correlation. This allowed me to self-consistently estimate pseudo redshifts of all the bursts with unknown r

Gamma-ray bursts (GRBs) are transients associated with the formation of compact objects. It had long been theorised that mergers of two neutron stars leading to the formation of a heavier neutron star or a black hole are the progenitors of the so-cal

We study the angular dependence of the flux from partially synchrotron self-absorbed conical jets (proposed by Blandford \& K{\"o}nigl). We consider the jet viewed from either a side or close to on axis, and in the latter case, either from the jet to

AstroSat is a multi-wavelength satellite launched on 2015 September 28. The CZT Imager of AstroSat on its very first day of operation detected a long duration gamma-ray burst (GRB) namely GRB 151006A. Using the off-axis imaging and spectral response
