High Energy Diffuse Gamma-Rays from Galactic Plane
The dominant part of the diffuse gamma rays beyond 1 TeV from the Galactic plane has been thought as due to the inverse Compton scattering of interstellar photons with high-energy cosmic-ray electrons. In these energy regions, diffuse gamma-ray observations give us unique information on the energy spectrum of high-energy electron in the interstellar space, since we cannot observe those electron...
متن کاملSearch for Gamma Ray Emission from Galactic Plane with Milagro
The majority of galactic gamma rays are produced by interaction of cosmic rays with matter. This results in a diffuse radiation concentrated in the galactic plane where the flux of cosmic rays and the density of material (mostly atomic, molecular and ionized hydrogen) is high. The interactions producing gamma rays include, among others, the decay of π’s produced in spallation reactions. Gamma e...
متن کاملVariable Unidentified Gamma-ray Sources near the Galactic Plane
In a recent paper, Romero et al. (1999) have presented the results of a positional correlation analysis of the low-latitude unidentified gamma-ray sources in the Third EGRET catalog with complete lists of galactic objects like supernova remnants, early type stars with strong stellar winds, and OB associations (considered as pulsar tracers). We have now carried out a study of those 42 sources at...
متن کاملSources of Cosmic Rays and Galactic Diffuse Gamma Radiation
The diffuse galactic gamma-ray spectrum measured by the EGRET experiment (Hunter et al. 1997) are interpreted within a scenario in which cosmic rays (CRs) are injected by three different kind of sources, (i) supernovae (SN) which explode into the interstellar medium (ISM), (ii) Red Supergiants (RSG), and (iii) Wolf-Rayet stars (WR), where the two latter explode into their pre-SN winds (Biermann...
متن کاملGalactic Origin of the Alleged Extragalactic Gamma-Ray Background Radiation
The diffuse gamma-ray background radiation (GBR) at high Galactic latitudes could be dominated by inverse Compton scattering (ICS) of cosmic ray (CR) electrons on the cosmic microwave background radiation (CBR) and on starlight (SL) in an extended CR halo of our galaxy. Assuming the locally observed CR electron spectrum beyond a few GeV, which follows from equilibrium between Fermi acceleration...
