Abstract

Although the dark matter hypothesis has stood all gravitational tests to date, we still yearn for a smoking-gun non-gravitational signal. Weakly Interacting Dark Matter candidates, thought to be in thermal equilibrium with the rest of the Standard Model in the early Universe, are getting closer to being ruled out. In this talk I will motivate the exploration of the realm of feeble interactions, in which dark matter is not a thermalized relic, and is therefore sensitive to the dynamics that occurred at the earliest moments of life of our Universe. Concretely, I will review the connection between freeze-in dark matter models and reheating, and the production of compact objects from thermal and disordered dynamics during inflation.

Biography

Marcos A. G. Garcia is a “Severo Ochoa” Postdoctoral Research Fellow at the Instituto de Fisica Teorica UAM-CSIC in Spain. He has a Ph.D. in Mathematical Physics from UNAM (Mexico), and a Ph.D. in Physics (High Energy Theory) from the University of Minnesota. His main research interest is the construction and study of particle physics models for the early Universe, in particular for inflation, baryogenesis and dark matter.
