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…
The role of electron capture decay in the precision era of Galactic cosmic-ray data
M. Borchiellini, D. Maurin, M. Vecchi
Electron capture (EC) decay relies on attachment and stripping cross-sections, that in turn, depend on the atomic number of the nucleus. We revisit the impact of EC decay in the co…
The peculiar new state of the blazar PKS 1510-089
H. M. Schutte, M. Zacharias, M. Böttcher +4
Contemporaneous multiwavelength observations with H.E.S.S., SALT, Fermi-LAT, Swift, and ATOM show that the blazar PKS 1510-089 suffered a significant decrease in its optical flux,…
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…
H.E.S.S. realtime follow-ups of IceCube high-energy neutrino alerts
Federica Bradascio, Halim Ashkar, Jowita Borowska +5
The evidence for multi-messenger photon and neutrino emission from the blazar TXS 0506+056 has demonstrated the importance of realtime follow-up of neutrino events by various groun…
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…
