The Fourth HAWC Catalog of Very-High-Energy Gamma-Ray Sources

R. Alfaro, C. Alvarez, E. Anita-Rangel +87

We present an updated catalog of TeV gamma-ray sources based on the fifth pass of data from the High-Altitude Water Cherenkov (HAWC) Observatory. This release benefits from improve…

Constraints on Axion-Like Particles from Ultra-High-Energy Observations of 3HWC J1908+063 with HAWC

R. Alfaro, C. Alvarez, A. Andres +92

Axion-like particles (ALPs) are hypothetical particles and compelling candidates for cold dark matter. Their existence could be probed through their conversions into photons in the…

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,…

Precise measurements of the cosmic ray proton energy spectrum in the "knee'' region

The LHAASO Collaboration, Zhen Cao, F. Aharonian +310

We report the high-purity identification of cosmic-ray (CR) protons and a precise measurement of their energy spectrum from 0.15 to 12 PeV using the Large High Altitude Air Shower…

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…
