Evidence for a spectral steepening of the gamma-ray emission from the Galactic Center ridge

A. Acharyya, F. Aharonian, H. Ashkar +130

Very-high-energy (VHE) -ray emission detected from the central molecular zone (CMZ) hints at diffusive propagation of cosmic rays (CRs) injected continuously near the Galactic c…

Curvature in the very-high energy gamma-ray spectrum of M87

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +132

The radio galaxy M87 is a variable very-high energy (VHE) gamma-ray source, exhibiting three major flares reported in 2005, 2008, and 2010. Despite extensive studies, the origin of…

TeV flaring activity of the AGN PKS 0625-354 in November 2018

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +139

Most -ray detected active galactic nuclei are blazars with one of their relativistic jets pointing towards the Earth. Only a few objects belong to the class of radio galaxies or…

Discovery of a Radiation Component from the Vela Pulsar Reaching 20 Teraelectronvolts

The H. E. S. S. Collaboration, :, F. Aharonian +178

Gamma-ray observations have established energetic isolated pulsars as outstanding particle accelerators and antimatter factories in the Galaxy. There is, however, no consensus rega…

H.E.S.S. discovery of very high energy gamma-ray emission from PKS 0625-354

H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +253

PKS 0625-354 (z=0.055) was observed with the four H.E.S.S. telescopes in 2012 during 5.5 hours. The source was detected above an energy threshold of 200 GeV at a significance level…

Population study of Galactic supernova remnants at very high -ray energies with H.E.S.S.

H. E. S. S. Collaboration, :, H. Abdalla +252

Shell-type supernova remnants (SNRs) are considered prime candidates for the acceleration of Galactic cosmic rays (CRs) up to the knee of the CR spectrum at $\mathrm{E} \approx \ma…
