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 ...

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).

Light speed variation from gamma ray bursts: criteria for low energy photons
European Physical Journal C: Particles and Fields, 2018 We examine a method to detect the light speed variation from gamma ray burst data observed by the Fermi Gamma-ray Space Telescope (FGST). We suggest new criteria to determine the characteristic time for low energy photons by the energy curve and the ...

Spider Invasion Across the Galaxy [PDF]
Journal of Astronomy and Space Sciences, 2014 The nature of the exotic stellar corpses which reincarnate by consuming their companion is reviewed. Apart from sucking life from their partners, they are actually eating the doomed companions away by their deadly and powerful particle/radiation beams.

The Fermi Gamma Ray Space Telescope discovers the Pulsar in the Young Galactic Supernova-Remnant CTA 1 [PDF]
Science, 2008 Energetic young pulsars and expanding blast waves [supernova remnants (SNRs)] are the most visible remains after massive stars, ending their lives, explode in core-collapse supernovae. The Fermi Gamma-Ray Space Telescope has unveiled a radio quiet pulsar located near the center of the compact synchrotron nebula inside the supernova remnant
