Description
[Connecting via Zoom] Cosmological observables, from the Lyman-alpha forest to the Milky Way substructure, offer unique avenues for probing dark matter and neutrino sectors. Moreover, they often reveal anomalies and tensions that could signal new physics. I will review the status of the recent early-universe and late-universe searches for dark matter and neutrino interactions, highlighting in particular the new simulation and EFT based efforts to understand their effects on the distribution of matter on small scales. I will highlight the interplay between complementary probes and discuss cosmological concordance in light of new data and modeling efforts.
