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,…

Validation of standardized data formats and tools for ground-level particle-based gamma-ray observatories

A. Albert, R. Alfaro, J. C. Arteaga-Velázquez +74

Ground-based gamma-ray astronomy is still a rather young field of research, with strong historical connections to particle physics. This is why most observations are conducted by e…
