Characterizing Candidate Blazar Counterparts of the Ultra-High-Energy Event KM3-230213A

KM3NeT Collaboration, MessMapp Group, LAT Collaboration +13

High-energy astrophysical neutrinos serve as crucial messengers for understanding hadronic acceleration processes and identifying the origins of cosmic rays, with blazars among the…

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…

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…

Constraints on axionlike particles from a combined analysis of three flaring flat-spectrum radio quasars

James Davies, Manuel Meyer, Garret Cotter

Many theories beyond the Standard Model of particle physics predict the existence of axionlike particles (ALPs) that mix with photons in the presence of a magnetic field. Searching…

The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 3

LAT collaboration, Marco Ajello, Luca Baldini +100

An incremental version of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-Large Area Telescope is presented. This version (4LAC-DR3) derives from the thir…
