Simultaneous multi-wavelength campaign on PKS 2005-489 in a high state
The H. E. S. S. Collaboration, the Fermi LAT Collaboration, : +345
The high-frequency peaked BL Lac object PKS 2005-489 was the target of a multi-wavelength campaign with simultaneous observations in the TeV gamma-ray (H.E.S.S.), GeV gamma-ray (Fe…
Discovery of extended VHE γ-ray emission from the vicinity of the young massive stellar cluster Westerlund 1
HESS Collaboration, A. Abramowski, F. Acero +198
Results obtained in very-high-energy (VHE; E > 100 GeV) γ-ray observations performed with the H.E.S.S. telescope array are used to investigate particle acceleration processes in th…
The 2010 very high energy gamma-ray flare & 10 years of multi-wavelength observations of M 87
The H. E. S. S. Collaboration, :, A. Abramowski +442
Abridged: The giant radio galaxy M 87 with its proximity, famous jet, and very massive black hole provides a unique opportunity to investigate the origin of very high energy (VHE;…
Systematic effects in the estimate of the local gamma-ray emissivity
Timur Delahaye, Pierre Salati, Armand Fiasson +1
We show in this letter that estimates of the local emissivity of γ-rays in the GeV-TeV range suffer uncertainties which are of the same order of magnitude as the current Fermi resu…
Supernova enhanced cosmic ray ionization and induced chemistry in a molecular cloud of W51C
C. Ceccarelli, P. Hily-Blant, T. Montmerle +3
Cosmic rays pervade the Galaxy and are thought to be accelerated in supernova shocks. The interaction of cosmic rays with dense interstellar matter has two important effects: 1) hi…
Discovery of the source HESS J1356-645 associated with the young and energetic PSR J1357-6429
HESS Collaboration, A. Abramowski, F. Acero +195
Several newly discovered very-high-energy (VHE; E > 100 GeV) gamma-ray sources in the Galaxy are thought to be associated with energetic pulsars. Among them, middle-aged (> 1E+4 yr…
