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…

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…

Dissipative Dark Substructure: The Consequences of Atomic Dark Matter on Milky Way Analog Subhalos
Caleb Gemmell, Sandip Roy, Xuejian Shen +4
Using cosmological hydrodynamical zoom-in simulations, we explore the properties of subhalos in Milky Way analogs that contain a sub-component of Atomic Dark Matter (ADM). ADM diff…
