CDHY Initiative

Working together to understand the sites of extreme acceleration

The Physics and Astrophysics of Very High Energy Sources: Observations, Phenomenology, Theory

The Columbia-DIAS-Heidelberg-Yale (CDHY) Initiative brings researchers together to understand Extreme Accelerators, the cosmic factories of very high energy particles.

What is the Initiative?

A joint network established by Columbia University (New York), Dublin Institute for Advanced Studies (Dublin), MPIK Heidelberg, and Yale University (New Haven).

Its focus is current topics in astroparticle physics: theory and phenomenology, observations, and interpretation.

Who is it for?

Motivated young researchers starting their careers, in particular PhD students and early-career postdocs.

All introductory lectures are open and recorded.

What do we organise?

  • Introductory lectures on current topics
  • Seminars on Extreme Accelerators
  • Focused workshops and small group meetings on specialised topics
  • Biennial summer schools for PhD students and early-career researchers
  • Visitor exchanges and joint research projects between the partner institutions
  • Seminars The Open Talk Series, 2021–2026
  • Workshops Focused mini-workshops and summer schools
  • People Members and collaborators
  • About Motivation and goals
