SNR are commonly assumed to accelerate the cosmic rays of E < 1 PeV observed at Earth. SNRs that interact with molecular clouds (MCs) are very promising targets to distinguish between leptonic and hadronic-induced gamma-ray emission. One of the brightest Fermi/LAT-detected SNRs interacting with a MC is W51C. Here we present a very detailed analysis of 5 years of Fermi/LAT data revealing a...

W51C is a supernova remant (SNR) known to be interacting with a molecular cloud (MC). Gamma-rays from hundreds of MeV up to tens of TeV were discovered towards this region. However a probable contamination from a pulsar wind nebula (PWN) prevents from directly investigating cosmic ray acceleration at the SNR shock. For the first time, thanks to new data analysis methods, H.E.S.S. reveals the...

Gamma-ray emission from supernova remnants (SNRs) can provide a unique window to observe the cosmic-ray acceleration believed to take place in these objects. Tycho is an especially good target for investigating hadronic cosmic-ray acceleration and interactions because it is a young type Ia SNR that is well studied in other wavelengths, and it is located in a relatively clean environment....

The Cygnus region is a very active region of our Galaxy, with many sources of GeV and TeV gamma-ray emission, such as supernova remnants, pulsar wind nebulae, high mass X-ray binaries and massive star clusters. A detailed study of the Cygnus region can give insight into the processes of particle acceleration in astrophysical sources. VERITAS is an array of four 12 meter diameter imaging...

The supernova remnant (SNR) W49B is a mixed-morphology remnant interacting with molecular clouds (MC) which originated in a Type Ib/Ic supernova explosion that occurred between one to four thousand years ago. It has one of the highest radio surface brightnesses, and is one of the brightest X-ray SNRs of our Galaxy. Gamma-ray observations of SNR/MC are a powerful tool to constrain the origin of...

Supernova remnants (SNRs) are considered prime candidates for the acceleration of Galactic cosmic-rays up to the knee of the cosmic-ray spectrum. More than 300 SNRs have been discovered in radio and higher frequency observations, of which $\sim 250$ fall into the H.E.S.S. Galactic Plane Survey region. Approximately 50 of these objects are spatially coincident with very-high-energy (VHE; E>0.1...
