Relativistic hydrodynamics simulations of supernova explosions within extragalactic jets
B. Longo, M. Perucho, V. Bosch-Ramon +2
Jets in active galactic nuclei have to cross significant distances within their host galaxies, meeting large numbers of stars of different masses and evolution stages in their path…
The physical properties of candidate neutrino-emitter blazars
Alessandra Azzollini, Sara Buson, Alexis Coleiro +5
The processes governing the production of astrophysical high-energy neutrinos are still debated, and the sources originating them remain an open question. Among the putative emitte…
Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
Dynamic and Radiative Implications of Jet-Star Interactions in AGN Jets
Gaëtan Fichet de Clairfontaine, Manel Perucho, José María Martí +1
The interactions between jets from active galactic nuclei (AGN) and their stellar environments significantly influence jet dynamics and emission characteristics. In low-power jets,…
Constraints on the intergalactic magnetic field using Fermi-LAT and H.E.S.S. blazar observations
H. E. S. S., Fermi-LAT Collaborations, : +134
Magnetic fields in galaxies and galaxy clusters are believed to be the result of the amplification of intergalactic seed fields during the formation of large-scale structures in th…
Constraining the cosmic-ray pressure in the inner Virgo Cluster using H.E.S.S. observations of M 87
H. E. S. S. Collaboration, :, F. Aharonian +160
The origin of the gamma-ray emission from M87 is currently a matter of debate. This work aims to localize the VHE (100 GeV-100 TeV) gamma-ray emission from M87 and probe a potentia…
Detection of extended gamma-ray emission around the Geminga pulsar with H.E.S.S
H. E. S. S. Collaboration, :, F. Aharonian +165
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 was discovered by…
Search for the evaporation of primordial black holes with H.E.S.S
H. E. S. S. collaboration, :, F. Aharonian +146
Primordial Black Holes (PBHs) are hypothetical black holes predicted to have been formed from density fluctuations in the early Universe. PBHs with an initial mass around $10^{14}-…
H.E.S.S. follow-up observations of GRB221009A
H. E. S. S. Collaboration, :, F. Aharonian +159
GRB221009A is the brightest gamma-ray burst ever detected. To probe the very-high-energy (VHE, \!100 GeV) emission, the High Energy Stereoscopic System (H.E.S.S.) began observat…
Gamma-ray observations of MAXI J1820+070 during the 2018 outburst
H. Abe, S. Abe, V. A. Acciari +439
MAXI J1820+070 is a low-mass X-ray binary with a black hole as a compact object. This binary underwent an exceptionally bright X-ray outburst from March to October 2018, showing ev…
Time-resolved hadronic particle acceleration in the recurrent Nova RS Ophiuchi
H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +171
Recurrent Novae are repeating thermonuclear explosions in the outer layers of white dwarfs, due to the accretion of fresh material from a binary companion. The shock generated by e…
Evidence of 100 TeV -ray emission from HESS J1702-420: A new PeVatron candidate
