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…

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…

Longtime Monitoring of TeV Radio Galaxies with HAWC

R. Alfaro, C. Alvarez, E. Anita-Rangel +85

We present the monitoring of the TeV-emitting radio galaxies M87, NGC~1275, 3C~264, and IC~310 with the High Altitude Water Cherenkov Observatory (HAWC) over a period of approximat…

Spectral study of very high energy gamma rays from SS 433 with HAWC

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +78

Very-high-energy (0.1-100 TeV) gamma-ray emission was observed in HAWC data from the lobes of the microquasar SS 433, making them the first set of astrophysical jets that were reso…
