Diffuse γ-rays from galactic halos
The γ-ray sky as we know it today is a composite of the emission from point sources and diffuse emission (see Fig.1). The most prominent feature is the galactic plane, in which interactions between cosmic rays and the thermal gas lead to γ-ray emission by π-decay and bremsstrahlung. On top of this diffuse emission we see point sources all over the map, part of them being pulsars, another part d...
متن کاملDIFFUSE GAMMA RAYS Galactic and Extragalactic Diffuse Emission
“Diffuse” gamma rays consist of several components: truly diffuse emission from the interstellar medium, the extragalactic background, whose origin is not firmly established yet, and the contribution from unresolved and faint Galactic point sources. One approach to unravel these components is to study the diffuse emission from the interstellar medium, which traces the interactions of high energ...
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 کاملThe Galactic contribution to high latitude diffuse γ-ray emission
Recent evidence for a large Galactic halo, based on cosmic-ray radioactive nuclei, implies a significant contribution from inverse Compton emission at high Galactic latitudes. We present predictions for the expected intensity distribution, and show that the EGRET gamma-ray latitude distribution is well reproduced from the plane to the poles. We show that the Galactic component at high latitudes...
متن کاملSe p 20 06 Contribution of unresolved point sources to the galactic diffuse emission
The detection by the HESS atmospheric Cherenkov telescope of fifteen new sources from the Galactic plane makes it possible to estimate the contribution of unresolved point sources like those detected by HESS to the diffuse Galactic emission measured by EGRET and recently at higher energies by the Milagro Collaboration. Assuming that HESS sources have all the same intrinsic lumi-nosity, the cont...
