Observations of M31 and M33 with the Fermi Large Area Telescope: a galactic center excess in Andromeda?

LAT Collaboration

The Fermi LAT has opened the way for comparative studies of cosmic rays (CRs) and high-energy objects in the Milky Way (MW) and in other, external, star-forming galaxies. Using 2 y…

Gamma-ray Blazars Within the First 2 Billion Years

Large Area Telescope Collaboration

The detection of high-redshift (z>3) blazars enables the study of the evolution of the most luminous relativistic jets over cosmic time. More importantly, high-redshift blazars t…
