Identifying the Gamma-Ray Emission of the Nearby Galaxy M83
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 ...

Interpretation and implications of the non‐detection of GeV spectrum excess by the Fermi Gamma‐ray Space Telescope in most gamma‐ray bursts [PDF]
Since the launch of the Fermi Gamma-ray Space Telescope on 2008 June 11, significant detections of high-energy emission have been reported only in six gamma-ray bursts (GRBs) until now.

High Energy Observational Investigations of Supernova Remnants and their Interactions with Surroundings [PDF]
Here we review the effort of Fermi Asian Network (FAN) in exploring the supernova remnants (SNRs) with state-of-art high energy observatories, including Fermi Gamma-ray Space Telescope and Chandra X-ray Observatory, in the period of 2011- 2012 ...

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

A Combined Radio Multi-Survey Catalog of Fermi Unassociated Sources
Approximately one-third of existing γ -ray sources identified by the Fermi Gamma-Ray Space Telescope are considered to be unassociated, with no known counterpart at other frequencies/wavelengths.

Spider Invasion Across the Galaxy [PDF]
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.
