Modelling energy-dependent pulsar light curves due to curvature radiation
Monica Barnard, Christo Venter, Alice K. Harding +1
Pulsars emit pulsed emission across the entire electromagnetic spectrum and their light curve phenomenology is strongly dependent on energy. This is also true for the gamma-ray wav…
Multi-TeV Emission From the Vela Pulsar
Alice K. Harding, Constantinos Kalapotharakos, Monica Barnard +1
Pulsed emission from the Vela pulsar at energies above 3 TeV has recently been detected by the H.E.S.S. II air-Cherenkov telescope. We present a model for the broad-band spectrum o…
Particle Transport within the Pulsar Wind Nebula HESS J1825-137
H. E. S. S. Collaboration, H. Abdalla, F. Aharonian +225
Aims: We present a detailed view of the pulsar wind nebula (PWN) HESS J1825-137. We aim to constrain the mechanisms dominating the particle transport within the nebula, accounting…
VHE -ray discovery and multi-wavelength study of the blazar 1ES 2322-409
H. E. S. S. Collaboration, :, H. Abdalla +232
A hotspot at a position compatible with the BL Lac object 1ES 2322-409 was serendipitously detected with H.E.S.S. during observations performed in 2004 and 2006 on the blazar PKS 2…
Searches for gamma-ray lines and `pure WIMP' spectra from Dark Matter annihilations in dwarf galaxies with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdalla +234
Dwarf spheroidal galaxies are among the most promising targets for detecting signals of Dark Matter (DM) annihilations. The H.E.S.S. experiment has observed five of these systems f…
First Ground-based Measurement of Sub-20 GeV to 100 GeV -rays from the Vela Pulsar with H.E.S.S. II
H. E. S. S. Collaboration, H. Abdalla, F. Aharonian +230
We report on the measurement and investigation of pulsed high-energy -ray emission from the Vela pulsar, PSR B083345, based on 40.3 hours of observations with the largest tel…
