The results of gamma-ray observations of the binary system HESS J0632+057 collected during 450 hours over 15 years, between 2004 and 2019, are presented. Data taken with the atmosp…
Clues on jet behavior from simultaneous radio-X-ray fits of GX339-4
S. Barnier, P. -O. Petrucci, J. Ferreira +9
Understanding the mechanisms of accretion-ejection during X-ray binaries outbursts has been a problem for several decades. It is still not clear yet what controls the spectral evol…
Multiple accelerated particle populations in the Cygnus Loop with Fermi-LAT
A. Tutone, J. Ballet, F. Acero +2
The Cygnus Loop (G74.0-8.5) is a very well-known nearby supernova remnant (SNR) in our Galaxy. Thanks to its large size, brightness, and angular offset from the Galactic plane, it…
