Enhanced HE and VHE gamma-ray activity from the FSRQ PKS 0346-27
On November 24, 2021, the Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-ray Space Telescope, observed increased gamma-ray activity from a source positionally consistent with the flat-spectrum radio quasar…
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. A continued VHE…
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). RS Ophiuchi…
GRB190829A: Detection of VHE gamma-ray emission with H.E.S.S.
The H.E.S.S. array of imaging atmospheric Cherenkov telescopes was used to carry out follow-up observations of the afterglow of GRB 190829A (Dichiara et al., GCN 25552). At a redshift of z = 0.0785 +/-…
