The 52 Brightest and Hardest GRBs Detected with the Gamma-ray Burst Monitor on Fermi [PDF]

, 2011
We present our results of the temporal and spectral analysis of a sample of 52 bright and hard gamma-ray bursts (GRBs) observed with the Fermi Gamma-ray Burst Monitor (GBM) during its first year of operation (July 2008-July 2009). Our sample was selected

Fast γ-ray Variability: A Common Feature and Powerful Probe for Jetted AGNs

Galaxies, 2018
Among the highly dynamical non-thermal universe, flashes of γ-ray photons from jets in active galactic nuclei (AGNs) are always attractive. Not only are they extraordinary observational phenomena, but they also become powerful probes of the jets ...

Identifying the Gamma-Ray Emission of the Nearby Galaxy M83

The Astrophysical Journal, 2023
We report on the detection of a γ -ray source at the position of the nearby star-forming galaxy (SFG) M83, which is found from our analysis of 14 yr of the data obtained with the Large Area Telescope on board the Fermi Gamma-ray Space Telescope (Fermi ...

Probing photon-ALP oscillations from the flat spectrum radio quasar 4C+21.35

Physics Letters B, 2022
Flat spectrum radio quasar (FSRQ) is the most luminous blazar at the GeV energies. In this paper, we probe the photon-axion-like particle (ALP) oscillation effect on the latest very-high-energy (VHE) γ-ray observations of the FSRQ 4C+21.35 (PKS 1222+216).
