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…

Study of the IC 443 region with the HAWC observatory

R. Alfaro, C. Alvarez, M. Araya +89

Supernova remnants are one potential source class considered a PeVatron (i.e. capable of accelerating cosmic rays above PeV energies). The shock fronts produced after the explosion…

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…

Ultra-High-Energy Gamma-Ray Bubble around Microquasar V4641 Sgr

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +89

Microquasars are laboratories for the study of jets of relativistic particles produced by accretion onto a spinning black hole. Microquasars are near enough to allow detailed imagi…

Testing the Molecular Cloud Paradigm for Ultra-High-Energy Gamma Ray Emission from the Direction of SNR G106.3+2.7

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +87

Supernova remnants (SNRs) are believed to be capable of accelerating cosmic rays (CRs) to PeV energies. SNR G106.3+2.7 is a prime PeVatron candidate. It is formed by a head region,…
