Cosmic rays from SNRs and TeV gamma-ray astronomy

Rowell, G. P (Astronomical Society of India, 2002)

The origin of Galactic cosmic rays is still a burning question that forms a major motivation for developments in ground-based gamma-ray astronomy. SNRs are long-thought to be sites for the acceleration of Galactic cosmic ...
High Energy Gamma-Ray Pulsars

Ramanamurthy, P. V (Astronomical Society of India, 1997)

To date we know the existence of six high energy gamma-ray (HEGR) pulsars and a possible seventh candidate, besides a solitary low energy gamma-ray pulsar. In this paper, we briefly summarize the observations on the seven ...
Long-Term Monitoring of Blazar PKS 0208-512: A Change of γ-Ray Baseline Activity from EGRET to Fermi Era

Ammenadka, Krishna Mohana; Bhattacharya, Debbijoy; Bhattacharyya, Subir; Bhatt, N; Stalin, C. S (Multidisciplinary Digital Publishing Institute, 2022-10)

The blazar PKS 0208-512 was in the lowest 𝛾 -ray brightness state during the initial 10 years of observations with the Fermi Gamma-ray Space Telescope (Fermi), which was an order of magnitude lower than its flux state ...
