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…

Machine learning reconstruction of cosmic ray parameters in EAS at HAWC

J. Jaimes, T. Capistrán, I. Torres

The High-Altitude Water Cherenkov (HAWC) Observatory comprises 300 water Cherenkov detectors, each equipped with four photomultipliers, located on the Volcán Sierra Negra in Mexico…

HAWC Performance Enhanced by Machine Learning in Gamma-Hadron Separation

R. Alfaro, C. Alvarez, A. Andrés +92

Improving gamma-hadron separation is one of the most effective ways to enhance the performance of ground-based gamma-ray observatories. With over a decade of continuous operation,…

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…
