Investigating a TeV-Halo Candidate around PSR J1928+1746 with HAWC

The HAWC Collaboration, R. Alfaro, C. Alvarez +94

We present an updated High-Altitude Water Cherenkov (HAWC) analysis of the crowded Galactic-plane area near PSR J1928+1746, which was previously linked to the extended source 3HWC…

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…

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…

Observation of the Galactic Center PeVatron Beyond 100 TeV with HAWC

A. Albert, R. Alfaro, C. Alvarez +99

We report an observation of ultra-high energy (UHE) gamma rays from the Galactic Center region, using seven years of data collected by the High-Altitude Water Cherenkov (HAWC) Obse…

Performance of the HAWC Observatory and TeV Gamma-Ray Measurements of the Crab Nebula with Improved Extensive Air Shower Reconstruction Algorithms

A . Albert, R. Alfaro, C. Alvarez +90

The High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory located on the side of the Sierra Negra volcano in Mexico, has been fully operational since 2015. The HAWC collaborat…

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.…
