Description
Galactic cosmic rays (CR), interstellar gamma-ray emission and radio emission
are related topics. CR electrons propagate in the Galaxy and interact with
the interstellar medium, producing inverse Compton and bremsstrahlung
emission measured in gamma rays, and synchrotron emission measured in
radio. After giving an overview of the latest results with Fermi on
interstellar gamma-ray emission, I will focus on complementary studies
of the radio emission from the Galaxy.
Using surveys over a wide range of radio
frequencies and polarization measurements, we derive from
synchrotron radiation constraints on the low-energy interstellar CR electron
spectrum, magnetic fields, CR source distribution and Galactic halo size.
