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…
Anisotropic CR diffusion and gamma-ray production close to supernova remnants, with an application to W28
Lara Nava, Stefano Gabici
Cosmic rays that escape their acceleration site interact with the ambient medium and produce gamma rays as the result of inelastic proton-proton collisions. The detection of such d…
Afterglow emission in Gamma-Ray Bursts: I. Pair-enriched ambient medium and radiative blast waves
L. Nava, L. Sironi, G. Ghisellini +2
Forward shocks caused by the interaction between a relativistic blast wave and the circum-burst medium are thought to be responsible for the afterglow emission in Gamma-Ray Bursts…
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…
A possible interpretation for the apparent differences in LFQPO types in microquasars
P. Varniere, M. Tagger, J. Rodriguez
In most microquasars, low-frequency quasi-periodic oscillations (LFQPO) have been classified into three types (A, B and C depending on the peak distribution in the PDS and the shap…
