Detection of VHE gamma-ray emission from the recurrent nova RS Ophiuchi with H.E.S.S.

The H.E.S.S. array of imaging atmospheric Cherenkov telescopes was used to carry out observations of the recurrent nova RS Ophiuchi currently in outburst and detected with Fermi/LAT (Cheung et al, ATel #14834).

H.E.S.S. observations of soft spectrum VHE gamma-ray emission from the recurrent nova RS Ophiuchi

Following the detection of very-high-energy gamma-ray emission the recurrent nova RS Ophiuchi currently in outburst (ATel #14844), H.E.S.S. observations continued on August 10th and August 11th for about 5h each night.
