Constraints on axion-like particles from ultra-high-energy observations of M87 with the HAWC observatory

R. Alfaro, C. Alvarez, A. Andrés +95

In this work, we perform an indirect search for axion-like particles (ALPs) through their hypothesized mixing with photons in the presence of magnetic fields. ALPs are a well-motiv…

Search for TeV emission from spider millisecond pulsars with HAWC

R. Alfaro, E. Anita-Rangel, M. Araya +90

Millisecond pulsars (MSPs) are observed to emit multi-wavelength radiation, from radio to GeV. Spider MSPs, which interact with their low-mass companion in close orbit (orbital per…

A Multi-messenger Search for Ultra-high-energy Gamma Rays in Coincidence with Neutrinos

R. Alfaro, C. Alvarez, A. Andrés +101

The last five years have shown us that ultra-high-energy (UHE; 100 TeV) gamma-ray sources are ubiquitous, but the nature of these sources remain highly uncertain. UHE gamma rays…

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…

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…

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…
