Unidentified Gamma-Ray Sources

2001
After γ-ray measurements opened a new window to observational astronomy, the question arose as to what kind of objects and which physical processes produce the observed emission. Because the early balloon experiments suffered from inadequate resolution and sky coverage, the first phenomenon associated with unidentified γ-ray-emitting sources was γ-ray ...

Unidentified gamma-Ray Sources: Hunting gamma-Ray Blazars

2012
One of the main scientific objectives of the ongoing Fermi mission is unveiling the nature of unidentified γ-ray sources (UGSs). Despite the major improvements of Fermi in the localization of γ-ray sources with respect to the past γ-ray missions, about one-third of the Fermi-detected objects are still not associated with low-energy counterparts ...

Galactic TeV gamma-ray sources

Astroparticle Physics, 1999
Abstract The observations of galactic TeV objects are summarized with emphasis on the astrophysical significance of recent positive detections from three pulsar driven nebulae, Crab Nebula, Vela, PSR 1706-44, and a historical supernova remnant, SN 1006.

Gamma-Ray Lines and High-Energy Sources

AIP Conference Proceedings, 2005
Gamma‐ray lines may provide diagnostic information on cosmic high energy sources: They originate from the decay of radioactive nucleosynthesis products, from positron annihilations, and from atomic nuclei which have been excited by energetic collisions.

Gamma-Ray Lines from CR Source Regions

Space Science Reviews, 2001
Gamma-ray lines arise from radioactivities produced in nucleosynthesis sites, and from deexcitation of nuclei which have been activated through energetic particle collisions. Since the bulk of nucleosynthesis activity relates to activities inside massive stars, both these processes are related to the likely sources of cosmic rays: Supernova remnants ...
