Constraining Dark Acoustic Oscillations with the High-Redshift UV Luminosity Function
Jared Barron, David Curtin, Hongwan Liu +3
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…
Dynamical Heating from Dark Compact Objects and Axion Minihalos: Implications for the 21-cm Signal
Badal Bhalla, Aurora Ireland, Hongwan Liu +2
The temperature of baryons at the end of the cosmic dark ages can be inferred from observations of the 21-cm hyperfine transition in neutral hydrogen. Any energy injection from the…
Dark Photons in the Radio Sky: II. Resonant Conversions in the Intergalactic Medium
Ethan Baker, Hongwan Liu
This is the second in a pair of papers forecasting the sensitivity of the Square Kilometre Array (SKA) to dark photons, a highly motivated, simple extension of the Standard Model.…
Dark Photons in the Radio Sky: I. Resonant Conversions in Halos
Ethan Baker, Hongwan Liu
Mixing between dark photons and visible photons leads to substantial anisotropies in the cosmic microwave background due to resonant conversions of visible photons into dark photon…
