Coupled Early Dark Energy

Speaker

Mark Trodden (University of Pennsylvania)

Description

I will describe how some of the fine-tuning problems of the early dark energy solution to the Hubble tension can be addressed using couplings to other fields already present in cosmology. I will discuss the formulation, the cosmology, and the constraints on such models, arising from both observational and theoretical considerations.
