Chandra and HESS observations of the supernova remnant CTB 37B
Aharonian, F.; Büsching, I.; De Jager, O.C.; Holleran, M.; Raubenheimer, B.C.; Venter, C.; H.E.S.S. Collaboration (EDP Sciences, 2008)We discovered the >100 GeV γ-ray source, HESS J1713−381, apparently associated with the shell-type supernova remnant (SNR) CTB37B, using HESS in 2006. In 2007 we performed X-ray follow-up observations with Chandra with ... -
Discovery of VHE y-rays from the BL Lacertae object PKS 0548-322
Aharonian, F.; Büsching, I.; Davids, I.D.; De Jager, O.C.; Holleran, M.; Raubenheimer, B.C.; Venter, C.; H.E.S.S. Collaboration (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 ... -
First detection of VHE y-rays from SN 1006 by HESS
Acero, F.; Büsching, I.; Davids, I.D.; De Jager, O.C.; Holleran, M.; Raubenheimer, B.C.; Venter, C.; H.E.S.S. Collaboration (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 ... -
Unidentified galactic high-energy sources as ancient pulsar wind nebulae in the light of new high energy observations and the new code
Tibolla, O.; Vorster, M.; De Jager, O.; Ferreira, S.E.S.; Venter, C. (AIP, 2012)In a Pulsar Wind Nebula (PWN), the lifetime of inverse Compton (IC) emitting e− exceeds the lifetime of its progenitor pulsar (as well as its shell-type remnant), but it also exceeds the age of those that emit via synchrotron ...
