Princeton University Gravity Initiative Seminar

Instant Folded Strings, Dark Energy and a Cyclic Bouncing Universe
Uri Peleg
12:30pm|Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: We present a wholly self-consistent, complete cyclic bouncing cosmology based on components drawn from string theory and constructed in a way that is under perturbative control throughout (e.g., with temperatures well below the string...

Princeton University Dark Cosmos Seminar

The Galaxy-Galaxy Strong Lensing Puzzle in Clusters
Isaque Dutra
4:00pm|Jadwin Hall, Joe Henry Room

Abstract: Gravitational lensing by galaxy clusters has emerged as a powerful tool to probe the standard CDM paradigm of structure formation in the Universe. Despite the remarkable explanatory power of CDM on large scales, tensions with observations...
