Observing Galactic Black Hole Sources in Hard X-rays
A. R. Rao
Observations of Galactic black hole sources are traditionally done in the classical X-ray range (2 -- 10 keV) due to sensitivity constraints. Most of the accretion power, however,…
Pulse-wise Amati correlation in Fermi GRBs
Rupal Basak, A. R. Rao
We make a detailed pulse-wise study of gamma-ray bursts (GRBs) with known redshift detected by \emph{Fermi}/Gamma Ray Burst Monitor (GBM). The sample contains 19 GRBs with 43 pulse…
Nature of GRBs observed by RT-2 on-board CORONAS-PHOTON satellite
D. Debnath, A. Nandi, S. K. Chakrabarti +2
The RT-2 Experiment, a low energy gamma-ray telescope, onboard CORONAS-PHOTON satellite is designed to study the temporal, spectral and spatial properties of the hard X-ray solar f…
A lingering non-thermal component in the GRB prompt emission: predicting GeV emission from the MeV spectrum
Rupal Basak, A. R. Rao
The high energy GeV emission of gamma-ray bursts (GRBs), detected by \emph{Fermi}/LAT, has a significantly different morphology compared to the lower energy MeV emission, detected…
Time resolved spectral analysis of the prompt emission of long gamma ray bursts with GeV Emission
A. R. Rao, Rupal Basak, J. Bhattacharya +4
We make a detailed time resolved spectroscopy of bright long gamma ray bursts (GRBs) which show significant GeV emissions (GRB 080916C, GRB 090902B, and GRB 090926A). In addition t…
The uncorrelated long term gamma-ray and X-ray variability of blazars and its implications on disk-jet coupling
Debbijoy Bhattacharya, Ranjeev Misra, A. R. Rao +1
We examine the long term (~10 years) gamma-ray variability of blazars observed by EGRET and Fermi and find that for six sources the average flux varied by more than an order of mag…
