Mock NYC

Date


The Mock conferences are curated workshops focused on the galaxy-halo connection, plus a new topic in each conference. The goal of Mock NYC is to bring together leading researchers in the galaxy-halo connection as well as key representatives from current and upcoming galaxy surveys to promote constructive and respectful discussions and collaborations.

Visit the Mock NYC 2026 Conference website for more information.
