In the latest post on our sister site Particlebites, Chris Karwin writes about new observations of the gamma ray excess at the Galactic center from Fermi.
The gamma-ray experiment HESS offers compelling evidence of a PeVatron that may help us better understand galactic cosmic rays
M31 discovered to be blowing vast bubbles of gamma rays, just like our own galaxy.
Today’s paper takes a look at combined data from two different gamma-ray experiments in the search for the products of dark matter annihilation
Today’s paper explores the galactic homes of superluminous supernovae — some of the brightest explosions in our universe.
Millisecond pulsars may be responsible for the extra gamma rays near the Galactic Center. Why haven’t we detected more of them?
