PKS 2005-489 at VHE: four years of monitoring with HESS and simultaneous multi-wavelength observations
(EDP Sciences, 2010)
Aims. Our aim is to study the very high energy (VHE; E>100 GeV) γ-ray emission from BL Lac objects and the evolution in time of their broad-band spectral energy distribution (SED).
Methods. VHE observations of the ...
Spatially resolved XMM-Newton analysis and a model of the nonthermal emission of MSH 15-52
(EDP Sciences, 2010)

First detection of VHE y-rays from SN 1006 by HESS
(EDP Sciences, 2010)
Aims. Recent theoretical predictions of the lowest very high energy (VHE) luminosity of SN 1006 are only a factor 5 below the previously published HESS upper limit, thus motivating further in-depth observations of this ...
Localizing the VHE y-ray source at the galactic centre
(Oxford University Press, 2010)
The inner 10 pc of our Galaxy contains many counterpart candidates of the very high energy
(VHE; >100 GeV) γ -ray point source HESS J1745−290. Within the point spread function
of the H.E.S.S. measurement, at least three ...
Accelerating high-energy pulsar radiation codes
(IOP Publishing, 2010)
Curvature radiation (CR) is believed to be a dominant mechanism for creating gamma-ray emission from pulsars and is emitted by relativistic particles that are constrained to move along curved magnetic field lines. Additionally, ...
Discovery of VHE y-rays from the BL Lacertae object PKS 0548-322
(EDP Sciences, 2010)
Aims. PKS 0548-322 (z=0.069) is a "high-frequency-peaked'' BL Lac object and a candidate very high energy (VHE, E >100 GeV) $\gamma$-ray emitter, due to its high X-ray and radio flux. Observations at the VHE band provide ...
Multi-wavelength observations of H 2356-309
(EDP Sciences, 2010)
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) observations of H 2356–309 were performed with ...
VHE y-ray emission of PKS 2155-304: spectral and temporal variability
(EDP Sciences, 2010)
Context. Observations of very high-energy γ-rays from blazars provide information about acceleration mechanisms occurring in their innermost regions. Studies of variability in these objects lead to a better understanding ...
Geometric modelling of radio and γ-ray light curves of 6 Fermi LAT pulsars
(Sissa Medialab, 2010)
The Fermi Large Area Telescope (LAT) has recently reported the detection of pulsed γ-rays
from 6 young pulsars (J0631+1036, J0659+1414, J0742−2822, J1420−6048, J1509−5850, and
J1718−3825), all exhibiting single-peaked ...
