Light Relics and Next Generation CMB Observations
Ongoing and future CMB observations will allow for fundamentally new insights into physics beyond the standard model and the very early universe. I will discuss theoretical targets for CMB constraints on light relics and the path toward reaching those goals. I will also highlight a particularly robust signature of light relics in the CMB power spectra and discuss the role of delensing the CMB in improving constraints.
