The first measurements of high-energy particles following solar flares in space and on the ground were performed during the 1940s, and by the 1960s the experiments were accurate enough to deduce spectral parameters. It was recognized that γ-ray continuum and, most importantly, γ-ray lines should be observable at high altitudes if a sufficiently large ...

Unidentified gamma-Ray Sources: Hunting gamma-Ray Blazars
2012One 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 ...

Unidentified Gamma-Ray Sources
2001After 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 ...

Galactic Sources of the Gamma Rays
2004Recent developments in experimental TeV gamma ray astronomy of Galactic sources are summarized, covering the Crab nebula as a standard candle, pulsars and pulsar nebulae, gamma ray emission by supernova remnants, and the newly discovered gamma-ray source at the Galactic centre. For an earlier review, see e.g. (1).
