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
Red giant stars are bright enough to see at the center of our galaxy, but they are missing. A new study puts stars in a wind tunnel to explore a possible way to dim the lights.
Millisecond pulsars may be responsible for the extra gamma rays near the Galactic Center. Why haven’t we detected more of them?
Observations of dust near the remains of a supernova in the center of our galaxy could have implications for dust production in the earliest galaxies.
The gas cloud G2 is rapidly approaching the galactic center. Can tidal disruption events with stellar remnants help constrain its orbit?
