A look back on Fermi in 2011
Conference proceedings from the 2011 Fermi Symposium highlight some of the major science applications of the gamma-ray space observatory.

The Fermi Large Area Telescope used a clever method of splitting electrons and positrons via the Earth’s magnetic field to show that there’s a significant excess of cosmic ray positrons at high energies – much more than can be explained using known cosmic ray processes.
The Crab Nebula has long been used as a standard candle in order to calibrate high-energy instruments … but it turns out it’s had us fooled all along! This paper gives an overview of what we’ve been missing from the Crab Nebula, and what this could mean for our understanding of high-energy astrophysics.
