H.E.S.S. detection of the PSR J0855-4644 nebula
F. Aharonian, H. Ashkar, M. Backes +131
HESS J0852-463 is a TeV γ-ray source located in the Galactic plane. The region consists of a supernova remnant (SNR, RX J0852.0-4622) with a shell-like morphology, commonly referr…
The Fourth HAWC Catalog of Very-High-Energy Gamma-Ray Sources
R. Alfaro, C. Alvarez, E. Anita-Rangel +87
We present an updated catalog of TeV gamma-ray sources based on the fifth pass of data from the High-Altitude Water Cherenkov (HAWC) Observatory. This release benefits from improve…
Constraining the nature of the most extreme Galactic particle accelerator. H.E.S.S. observations of the microquasar V4641 Sgr
A. Acharyya, F. Aharonian, H. Ashkar +131
Microquasars have emerged as promising candidates to explain the cosmic-ray flux at petaelectronvolt energies. LHAASO observations revealed V4641~Sgr as the most extreme example so…
Probing the mass composition of TeV cosmic rays with HAWC
J. C. Arteaga-Velázquez
In this contribution, we have investigated the energy spectra of the elemental mass groups of cosmic rays for the Light (H+He), medium (C+O) and heavy (Ne-Fe) components using the…
Energy-dependent gamma-ray morphology estimation tool in Gammapy
K. Feijen, R. Terrier, B. Khélifi +4
An understanding of the energy dependence of gamma-ray sources can yield important information on the underlying emission mechanisms. However, despite the detection of energy-depen…
Science Prospects for the Southern Wide-field Gamma-ray Observatory: SWGO
SWGO Collaboration, P. Abreu, R. Alfaro +303
Ground-based gamma-ray astronomy is now well established as a key observational approach to address critical topics at the frontiers of astroparticle physics and high-energy astrop…
