The 21-cm line of hydrogen is emerging as a promising probe of the first 0.1 billion years of cosmic history. We conduct a suite of hydrodynamical simulations to precisely model the impact of sub-Mpc structure formation on 21-cm emission during these early epochs. We find that this small-scale matter clumping turns highly nonlinear at z≲30, leading to ~10% changes in the sky-averaged 21-cm...
