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…

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…

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…

Extended TeV Halos May Commonly Exist around Middle-Aged Pulsars

A. Albert, R. Alfaro, C. Alvarez +81

Extended gamma-ray emission around isolated pulsars at TeV energies, also known as TeV halos, have been found around a handful of middle-aged pulsars. The halos are significantly m…

Orbital Modulation of Gamma-Rays Beyond 100 TeV from LS 5039

R. Alfaro, M. Araya, J. C. Arteaga-Velázquez +88

Gamma-ray binaries are systems composed of a compact object orbiting a massive companion star. The interaction between these two objects can drive relativistic outflows, either jet…
