Description

The 2025 Cosmology Summer Fest is in honor of Marc Kamionkowski and Robert Caldwell’s 60th birthdays. The event will be a 2.5-day science workshop during which we will discuss recent progress in a range of topics in theoretical and data-driven cosmology.

This event includes a reception on Wednesday evening 18:00-20:00 and a banquet dinner on Thursday 18:00-21:00, for registered participants, in the Atrium of the Bloomberg Center for Physics and Astronomy.

Link to suggested questions for Marc and Robert during Thursday's discussion.
