Constraints on Axion-Like Particles from Ultra-High-Energy Observations of 3HWC J1908+063 with HAWC
R. Alfaro, C. Alvarez, A. Andres +92
Axion-like particles (ALPs) are hypothetical particles and compelling candidates for cold dark matter. Their existence could be probed through their conversions into photons in the…
Axion-like Particles and their Possible Impact on the Very High-Energy Spectrum of M87 Observed by LHAASO
A. Pratts, D Avila Rojas, J. Serna-Franco +2
The detection of very high-energy (VHE) gamma rays from the active galaxy M87 by LHAASO, showing a possible spectral hardening around TeV, motivates the search for new physics…
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…
Comparing HAWC blazars light curves with different data reconstruction versions
J. A. García-González, M. M. González
We present a comparison of the flux normalization of HAWC sources using 17 months of data that was processed using two different versions of the official data reconstruction used f…
The HAWC ultra-high-energy gamma-ray map with more than 5 years of data
Kelly Malone, José Andrés García González, Patrick Harding
In 2020, the HAWC Collaboration presented the first catalog of gamma-ray sources emitting above 56 TeV and 100 TeV. With nine sources detected, this was the highest-energy source c…
An updated survey of Active Galaxies with the HAWC gamma-ray observatory
Fernando Ureña-Mena, Alberto Carramiñana, Daniel Rosa-González +2
We present an update of the survey of Active Galaxies with the High Altitude Water Cherenkov (HAWC) gamma-ray observatory. This work adds 567 days of HAWC data to the previously pu…
Study of the long-term Very High Energy emission of the blazars 1ES 1215+3031 and VER J0521+211 with the HAWC gamma-ray observatory
Fernando Ureña-Mena, Alberto Carramiñana, Anna Lia Longinotti +2
Blazars are the most abundant type of extragalactic gamma-ray source, usually presenting high variability across the electromagnetic spectrum. Their Very High Energy (VHE, above 0.…
GRB 221009A: Spectral signatures based on ALPs candidates
D. Avila Rojas, S. Hernández-Cadena, M. M. González +3
GRB 221009A has posed a significant challenge to our current understanding of the mechanisms that produce TeV photons in gamma-ray bursts (GRB). On one hand, the Klein-Nishina (KN)…
GRB 221009A: A light dark matter burst or an extremely bright Inverse Compton component?
M. M. González, D. Avila Rojas, A. Pratts +5
Gamma-ray bursts (GRBs) have been considered as potential very high-energy photon emitters due to the large amount of energy released as well as the strong magnetic fields involved…
