Binary Millisecond Pulsar Discovery via Gamma-Ray Pulsations
H. J. Pletsch, L. Guillemot, H. Fehrmann +150
Millisecond pulsars, old neutron stars spun-up by accreting matter from a companion star, can reach high rotation rates of hundreds of revolutions per second. Until now, all such "…
The nature of gamma-ray emission of Tycho's supernova remnant
E. G. Berezhko, L. T. Ksenofontov, H. J. Voelk
The nature of the recently detected HE and VHE gamma-ray emission of Tycho's supernova remnant (SNR) is studied. A nonlinear kinetic theory of cosmic ray (CR) acceleration in super…
CTA and cosmic-ray diffusion in molecular clouds
G. Pedaletti, D. F. Torres, S. Gabici +3
Molecular clouds act as primary targets for cosmic-ray interactions and are expected to shine in gamma-rays as a by-product of these interactions. Indeed several detected gamma-ray…
Pulsar Prospects for the Cherenkov Telescope Array
T. Hassan, S. Bonnefoy, M. Lopez +6
In the last few years, the Fermi-LAT telescope has discovered over a 100 pulsars at energies above 100 MeV, increasing the number of known gamma-ray pulsars by an order of magnitud…
On the origin of very high energy gamma-rays from radio galaxies
Frank M. Rieger
Radio galaxies have emerged as a new gamma-ray emitting source class on the extragalactic sky. With their jets misaligned, i.e. not directly pointing towards us, they offer a uniqu…
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…

The binary systems that have been detected in gamma rays have proven very useful to study high-energy processes, in particular particle acceleration, emission and radiation reproce…
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…
Nonthermal emission of supernova remnant SN 1006 revisited: theoretical model and the H.E.S.S. results
E. G. Berezhko, L. T. Ksenofontov, H. J. Voelk
The properties of the Galactic supernova remnant (SNR) SN 1006 are theoretically re-analyzed in the light of the recent H.E.S.S. results. Nonlinear kinetic theory is used to determ…
Gamma-ray signatures of cosmic ray acceleration, propagation, and confinement in the era of CTA
F. Acero, A. Bamba, S. Casanova +11
Galactic cosmic rays are commonly believed to be accelerated at supernova remnants via diffusive shock acceleration. Despite the popularity of this idea, a conclusive proof for its…
