On the cosmic-ray distribution in the Galactic Center region: New insights from H.E.S.S

J. Devin, A. Lemière, K. Streil +2

We performed a spectro-morphological analysis of the diffuse emission in the Galactic center region with H.E.S.S. gamma-ray data. We relied on templates to model the diffuse emissi…

Detection of very-high-energy gamma-ray emission from Eta Carinae during its 2020 periastron passage

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +137

The colliding-wind binary system Carinae has been identified as a source of high-energy (HE, below 100\,GeV) and very-high-energy (VHE, above 100\,GeV) gamma rays i…

Very-high-energy -ray emission from young massive star clusters in the Large Magellanic Cloud

F. Aharonian, F. Ait Benkhali, J. Aschersleben +129

The Tarantula Nebula in the Large Magellanic Cloud is known for its high star formation activity. At its center lies the young massive star cluster R136, providing a significant am…

H.E.S.S. observations of the 2021 periastron passage of PSR B1259-63/LS 2883

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +141

PSR B1259-63 is a gamma-ray binary system that hosts a pulsar in an eccentric orbit, with a 3.4 year period, around an O9.5Ve star. At orbital phases close to periastron passages,…

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…

Acceleration and transport of relativistic electrons in the jets of the microquasar SS 433

F. Aharonian, F. Ait Benkhali, J. Aschersleben +161

SS 433 is a microquasar, a stellar binary system with collimated relativistic jets. We observed SS 433 in gamma rays using the High Energy Stereoscopic System (H.E.S.S.), finding a…

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…

Joint H.E.S.S. and Fermi-LAT analysis of the region around PSR J1813-1749

T. Wach, A. M. W. Mitchell, V. Joshi +1

HESS J1813-178 is one of the brightest sources detected during the first HESS Galactic Plane survey. The compact source, also detected by MAGIC, is believed to be a pulsar wind neb…

Modelling of highly extended Gamma-ray emission around the Geminga Pulsar as detected with H.E.S.S

A. M. W. Mitchell, S. Caroff

Geminga is an enigmatic radio-quiet gamma-ray pulsar located at a mere 250 pc distance from Earth. Extended very-high-energy gamma-ray emission around the pulsar has been detected…
