H.E.S.S. constraints on Dark Matter annihilations towards the Sculptor and Carina Dwarf Galaxies
HESS Collaboration, A. Abramowski, F. Acero +192
The Sculptor and Carina Dwarf spheroidal galaxies were observed with the H.E.S.S. Cherenkov telescope array between January 2008 and December 2009. The data sets consist of a total…
Fermi-LAT observations of the exceptional gamma-ray outbursts of 3C 273 in September 2009
A. A. Abdo et al.
We present the light curves and spectral data of two exceptionally luminous gamma-ray outburts observed by the Large Area Telescope (LAT) experiment on board Fermi Gamma-ray Space…
Discovery and follow-up studies of the extended, off-plane, VHE gamma-ray source HESS J1507-622
H. E. S. S. Collaboration, F. Acero, F. Aharonian +167
Context: The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV-100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles f…
Revisiting the Westerlund 2 Field with the H.E.S.S. Telescope Array
The HESS Collaboration, A. Abramowski, F. Acero +194
Aims. Previous observations with the H.E.S.S. telescope array revealed the existence of extended very-high-energy (VHE; E>100 GeV) γ-ray emission, HESS J1023-575, coincident with t…
Detection of 16 Gamma-Ray Pulsars Through Blind Frequency Searches Using the Fermi LAT
LAT Collaboration
Pulsars are rapidly-rotating, highly-magnetized neutron stars emitting radiation across the electromagnetic spectrum. Although there are more than 1800 known radio pulsars, until r…
η Carinae: a very large hadron collider
R. Walter, C. Farnier, J. -C. Leyder
Eta Carinae is the colliding wind binary with the largest mass loss rate in our Galaxy and the only one in which hard X-ray emission has been detected. Eta Carinae is therefore a p…
