Simultaneous H.E.S.S. and Chandra observations of Sagittarius A* during an X-ray flare
H. E. S. S. Collaboration, :, F. Aharonian
The rapidly varying (~10 minute timescale) non-thermal X-ray emission observed from Sgr A* implies that particle acceleration is occuring close to the event horizon of the supermas…
A photometric study of the southern Blazhko star SS For Unambiguous detection of quintuplet components
Katrien Kolenberg, Elisabeth Guggenberger, Thebe Medupe +6
We present our analysis of photometric data in the Johnson B and V filter of the southern Blazhko star SS For. In parallel, we analyzed the V observations obtained with the ASAS-3…
Very high energy gamma-ray observations of the galaxy clusters Abell 496 and Abell 85 with H.E.S.S
H. E. S. S. Collaboration, :, F. Aharonian
Aims: The nearby galaxy clusters Abell 496 and Abell 85 are studied in the very high energy (VHE, E > 100 GeV) band to investigate VHE cosmic rays (CRs) in this class of objects wh…
The energy spectrum of cosmic-ray electrons at TeV energies
H. E. S. S. Collaboration, :, F. Aharonian
The very large collection area of ground-based gamma-ray telescopes gives them a substantial advantage over balloon/satellite based instruments in the detection of very-high-energy…
Probing the Nature of the Vela X Cocoon
Stephanie M. LaMassa, Patrick O. Slane, Okkie C. de Jager
Vela X is a pulsar wind nebula (PWN) associated with the active pulsar B0833-45 and contained within the Vela supernova remnant (SNR). A collimated X-ray filament ("cocoon") extend…
Limits on an Energy Dependence of the Speed of Light from a Flare of the Active Galaxy PKS 2155-304
H. E. S. S. Collaboration, :, F. Aharonian
In the past few decades, several models have predicted an energy-dependence of the speed of light in the context of quantum gravity. For cosmological sources such as active galaxie…
