High-Statistics Measurement of the Cosmic-Ray Electron Spectrum with H.E.S.S

F. Aharonian, F. Ait Benkhali, J. Aschersleben +144

Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators an…

Multi-wavelength study of OT 081: broadband modelling of a transitional blazar

MAGIC Collaboration, H. Abe, S. Abe +270

OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…

Ultra-High-Energy Gamma-Ray Bubble around Microquasar V4641 Sgr

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +89

Microquasars are laboratories for the study of jets of relativistic particles produced by accretion onto a spinning black hole. Microquasars are near enough to allow detailed imagi…

Detectability of Supernova Remnants with the Southern Wide-field Gamma-ray Observatory

Nick Scharrer, Samuel T. Spencer, Vikas Joshi +1

Supernova remnants (SNRs) are likely sources of hadronic particle acceleration within our galaxy, contributing to the galactic cosmic ray flux. Next-generation instruments, such as…

TeV Analysis of a Source Rich Region with HAWC Observatory: Is HESS J1809-193 a Potential Hadronic PeVatron?

A. Albert, R. Alfaro, C. Alvarez +79

HESS J1809-193 is an unidentified TeV source, first detected by the High Energy Stereoscopic System (H.E.S.S.) Collaboration. The emission originates in a source-rich region that i…

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,…
