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…

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,…

Search for joint multimessenger signals from potential galactic cosmic-ray accelerators with HAWC and IceCube

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +489

The origin of high-energy galactic cosmic rays is yet to be understood, but some galactic cosmic-ray accelerators can accelerate cosmic rays up to PeV energies. The high-energy cos…

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…

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…
