Title: 
STAG Seminar: Origin and Phenomenology of Dark Radiation
Abstract: 
Dark radiation is a natural extension of Lambda CDM for which there are tentative observational hints. I discuss how dark radiation arises naturally in UV-complete models of the early universe, and explain the phenomenology associated to it. The talk is based on 1208.3562 and 1304.1804.
