CDHY PeVatron Workshop
Nevis Labs, Columbia University
Unveiling Galactic PeVatrons with frontier multi-messenger observations and theoretical models
The 3rd CDHY workshop “Unveiling Galactic PeVatrons with frontier multi-messenger observations and theoretical models,” will be held in-person at Columbia University Nevis Labs, near New York City, on Oct 8-10, 2025. The recent discoveries of over 50 ultra-high-energy (UHE; > 100 TeV) gamma-ray sources and neutrino emissions in the Galactic Plane have marked a paradigm shift in the century-long history of cosmic-ray astrophysics. While the UHE telescopes (LHAASO, HAWC, and Tibet AS gamma) operate as PeVatron search engines, IACTs (H.E.S.S, VERITAS, and MAGIC) and X-ray observations are crucial for identifying the most energetic particle acceleration sites. Taking advantage of the wealth of observational data from current multi-messenger instruments, we would like to address the questions of what are the Galactic PeVatrons, and how do they accelerate particles to PeV energies.
This workshop aims to bring the latest observational results, theoretical models, and the experts to Columbia University and/or New York. We will discuss the future visions for understanding the Galactic PeVatron phenomena most comprehensively with the upcoming gamma-ray, X-ray, neutrino and radio telescopes over the next decade.
About CDHY: The Columbia-DIAS-Heidelberg-Yale (CDHY) Initiative is a series of seminars/meetings established by Columbia University (New York), Dublin Institute for Advanced Studies (Dublin), MPIK Heidelberg, and Yale University (New Haven).
