| Zusammenfassung |
| Synchrotron diffuse radiation (SDR) emission is one of the major Galactic
components, in the 100 MHz up to 100 GHz frequency range. Its spectrum and
sky map provide valuable measure of the galactic cosmic ray electrons (GCRE)
in the relevant energy range, as well as of the strength and structure of the
Galactic magnetic fields (GMF), both regular and random ones. This emission
is an astrophysical sky foreground for the study of the Cosmic Microwave
Background (CMB), and the extragalactic microwave measurements, and it needs
to be modelled as better as possible. In this regard, in order to get an
accurate description of the SDR in the Galaxy, we use – for the first time
in this context – 3-dimensional GCRE models obtained by running the
DRAGON code. This allows us to account for a realistic spiral arm
pattern of the source distribution, demanded to get a self-consistent
treatment of all relevant energy losses influencing the final synchrotron
spectrum. |
