Abstract

Nine years ago, the EGRET gamma-ray telescope fell into the ocean,
leaving behind a mystery. What were all those sources of GeV emission
in our Galaxy? Observations using every wavelength, from 90cm radio to 20 TeV gamma-rays, have been used to try and identify what these
sources were. After less than one year of operations by the Fermi LAT
(formerly known as GLAST), the mystery has, for the most part, been
solved. The majority seem to be pulsars. Young pulsars, middle-aged
pulsars, millisecond pulsars, radio-loud and radio-quiet pulsars,
pulsars in binaries, pulsars with radio to TeV emitting nebulae,
pulsars near and far. However, there are still a few mysteries left to solve. I will give an overview of what was known about Galactic GeV sources, what has been revealed by Fermi, and what is still left to figure out.
