| description | Diffuse gamma ray emission from the Galactic center at 2-3 GeV, as well as
the 12 TeV gamma ray excess in the Galactic disk, remain open for debate and
represent the missing puzzles in the complete picture of the high-energy
Milky Way sky. Our papers emphasize the importance of understanding all of
the populations that contribute to the diffuse gamma background in order to
discriminate between the astrophysical sources such as supernova remnants
and pulsars, and something that is expected to be seen in gamma rays and is
much more exotic - dark matter. We analyze two separate data sets that have
been measured in different energy ranges from the “Fermi-LAT” and “Milagro”
telescopes, using these as a powerful tool to limit and test our analytical
source population models. We model supernova remnants and pulsars,
estimating the number of still undetected ones that contribute to the
diffuse background, trying to explain both the Galactic center and the 12
TeV excess. Furthermore, we aim to predict the number of soon to be
detected sources with new telescopes, such as the “HAWC”. |
