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 scientists from 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
