Measurement of the extragalactic background light imprint on the spectra of the brightest blazars observed with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +195
The extragalactic background light (EBL) is the diffuse radiation with the second highest energy density in the Universe after the cosmic microwave background. The aim of this stud…
Multiwavelength observations of GRB 110731A: GeV emission from onset to afterglow
LAT Collaboration, GBM Collaboration, Swift Collaboration +2
We report on the multiwavelength observations of the bright, long gamma-ray burst \GRB, by the \Fermi and \Swift observatories, and by the MOA and GROND optical telescopes. The ana…
Identification of HESS J1303-631 as a Pulsar Wind Nebula through gamma-ray, X-ray and radio observations
The H. E. S. S. Collaboration, :, A. Abramowski +196
The previously unidentified very high-energy (VHE; E > 100 GeV) γ-ray source HESS J1303-631, discovered in 2004, is re-examined including new data from the H.E.S.S. Cherenkov teles…
Probing the extent of the non-thermal emission from the Vela X region at TeV energies with H.E.S.S
A. Abramowski, F. Acero, F. Aharonian +196
Vela X is a region of extended radio emission in the western part of the Vela constellation: one of the nearest pulsar wind nebulae (PWNe), and associated with the energetic Vela p…
Discovery of gamma-ray emission from the extragalactic pulsar wind nebula N157B with the High Energy Stereoscopic System
HESS Collaboration, A. Abramowski, F. Acero +195
We present the significant detection of the first extragalactic pulsar wind nebula (PWN) detected in gamma rays, N157B, located in the large Magellanic Cloud (LMC). Pulsars with hi…
Constraints on the gamma-ray emission from the cluster-scale AGN outburst in the Hydra A galaxy cluster
HESS Collaboration, A. Abramowski, F. Acero +193
In some galaxy clusters powerful AGN have blown bubbles with cluster scale extent into the ambient medium. The main pressure support of these bubbles is not known to date, but cosm…
