The data recorded by ARGO-YBJ in more than 5 years have been analyzed todetermine the diffuse gamma ray emission from the Galactic plane. The spatial distribution of the diffuse gamma rays and their energy spectra at Galactic longitudes 25^o < l <100^o o and Galactic latitudes |b|<5^o have been studied. The regions with 40^o< l <100^o and 65^o < l <85^o have been focused, where Milagro...

Geminga is a radio-quiet pulsar ~250 parsecs from Earth that was first discovered as a GeV gamma-ray source and then identified as a pulsar. Milagro observed an extended TeV source spatially consistent with Geminga. HAWC observes a similarly extended source. Observations of Geminga’s flux and extension will be presented.

A number of Galactic sources emit GeV-TeV gamma rays that are produced through leptonic and/or hadronic mechanisms. Spectral analysis in this energy range is crucial in order to understand the emission mechanisms. The HAWC Gamma-Ray Observatory, with a large field of view and location at 19º N latitude, is surveying the Galactic Plane from high Galactic longitudes down to near the Galactic...

RCW 86 (also known as G315.4-2.3 or MSH 14-3) is a young supernova remnant about 1800 years old with a shell-like structure in the optical, radio, infrared and X-rays regimes with a diameter of about 40'.
We will show detailed morphological and spectral studies of the TeV gamma-ray data measured with the H.E.S.S. telescope system. These studies reveal for the first time a shell-like...

Oral contribution
Supernovae Remnants (SNRs) are thought to be the primary source of galactic cosmic rays observed on Earth. Detected in radio, infrared, X-rays and at high (GeV) and very high energy (TeV) gamma rays, RCW 86 is a good candidate for efficient particle acceleration and might be the remnant of the historical supernova SN 185. Using more than 6 years of data acquired by the Fermi Large Area...

Amongst the population of TeV gamma-ray sources detected with the High Energy Stereoscopic System (H.E.S.S.) in the Galactic plane, clearly identified supernova remnant (SNR) shells constitute a small but precious source class. TeV-selected SNRs are prime candidates for efficient cosmic-ray acceleration. In this work, we present new SNR candidates that have been identified in the entire...
