Abstract

I discuss particle physics models for dark matter that can leave a non-trivial imprint in the dark matter density perturbations and serve as targets of precise cosmological measurements. Scenarios include sterile neutrino dark matter enabled by novel neutrino self-interaction, thermal relic via an entropy dilution mechanism, and dark matter mass generated by a first-order phase transition in the early universe. Interplay with other probes will also be discussed when applicable.
