Probing the small-scale matter power spectrum with large-scale 21-cm data

The distribution of matter fluctuations in our universe is key for understanding the nature of dark matter and the physics of the early cosmos. Different observables have been able to map this distribution at large scales, corresponding to wave numbers k ≲ 10 Mpc−1 , but smaller scales remain much l...
