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…

Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS

LAT Collaboration, S. Abdollahi, L. Baldini +586

Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…

Absence of TeV halos around millisecond pulsars

A. U. Abeysekara, R. Alfaro, C. Alvarez +82

TeV halos are extended very-high-energy (VHE; 0.1-100 TeV) gamma-ray emission around middle-aged pulsars. So far they have only been found around isolated pulsars, but it has been…

Study of long-term spectral evolution and X-ray and Gamma-ray correlation of blazars seen by HAWC

R. Alfaro, C. Alvarez, A. Andrés +94

The HAWC Observatory collected 6 years of extensive data, providing an ideal platform for long-term monitoring of blazars in the Very High Energy (VHE) band, without bias towards s…

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…
