The observed spectra of astrophysical neutrinos and gamma rays do not match up using current models. Today’s paper may have solved this quandary.
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.
