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…
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…
Multi-wavelength Observations of H 2356-309
HESS Collaboration, A. Abramowski, F. Acero +184
AIMS: The properties of the broad-band emission from the high-frequency peaked BL Lac H 2356-309 (z=0.165) are investigated. METHODS: Very High Energy (VHE; E > 100 GeV) observatio…
Constraints on the kinematics of the 44Ti ejecta of Cassiopeia A from INTEGRAL/SPI
Pierrick Martin, Jürgen Knödlseder, Jacco Vink +2
The medium-lived 44Ti isotope is synthesised by explosive Si-burning in core-collapse supernovae. It is extremely sensitive to the dynamics of the explosion and therefore can be us…
