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…

The magnetic field structure in NGC 253 in presence of a galactic wind

V. Heesen, M. Krause, R. Beck +1

We present radio continuum polarimetry observations of the nearby edge-on galaxy NGC 253 which possesses a very bright radio halo. Using the vertical synchrotron emission profiles…

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…
