Simons Satellite Meeting on Celestial Holography 2025

15 Apr 2025, 09:00 → 16 Apr 2025, 17:00 US/Eastern

Timothy Adamo (University of Edinburgh)

A two-day workshop with the Simons Collaboration on Celestial Holography taking place on 15-16 April 2025 at the Andaz 5th Avenue in New York City. This meeting will feature a variety of talks related to celestial holography and its applications, as well as ample time for discussion and interaction. 

This satellite meeting is immediately followed by the Annual Meeting of the Simons Collaboration, on 17-18 April 2025 at the Flatiron Institute.

(This is an invitation-only meeting.)
