Search for Signatures of Dark Matter Annihilation in the Galactic Center with HAWC
R. Alfaro, C. Alvarez, A. Andrés +109
We conduct an indirect dark matter (DM) search in the Galactic Center, focusing on a square region within in Galactic longitude and latutide, using 2,865 days of da…
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…
Extended TeV Halos May Commonly Exist around Middle-Aged Pulsars
A. Albert, R. Alfaro, C. Alvarez +81
Extended gamma-ray emission around isolated pulsars at TeV energies, also known as TeV halos, have been found around a handful of middle-aged pulsars. The halos are significantly m…
Orbital Modulation of Gamma-Rays Beyond 100 TeV from LS 5039
R. Alfaro, M. Araya, J. C. Arteaga-Velázquez +88
Gamma-ray binaries are systems composed of a compact object orbiting a massive companion star. The interaction between these two objects can drive relativistic outflows, either jet…
