Strongest constraints on dark acoustic oscillations from the Lyman-alpha forest

Zhihan Yuan, Caleb Gemmell, Keir K. Rogers +4

We set the first constraints on a small-scale dark acoustic oscillation (DAO) in the linear matter power spectrum arising from dark sector interactions, with a full forward model o…

CMB Spectral Distortions from Resonant Conversions in Atomic Dark Sectors

Duncan K. Adams, Jared Barron, Bryce Cyr +1

Dark sectors consisting of atomic constituents (electrons, protons, and photons) offer a well-motivated extension to the Standard Model while providing multiple avenues for phenome…

Pushing the Limits of Atomic Dark Matter: First-Principles Recombination Rates and Cosmological Constraints

Jared Barron, Rouven Essig, Megan H. McDuffie +2

Minimal atomic dark matter with its distinctive cooling mechanisms offers an instructive framework for understanding the potential impact of dark matter on small-scale structure fo…

Constraining Dark Acoustic Oscillations with the High-Redshift UV Luminosity Function

Jared Barron, David Curtin, Hongwan Liu +2

Dark acoustic oscillations (DAOs) in the matter power spectrum can arise in many different dark sector models, and can imprint on a variety of cosmological observables. In this wor…
