Streaming Velocity Effects on the Post-reionization 21 cm Baryon Acoustic Oscillation Signal

The relative velocity between baryons and dark matter in the early Universe can suppress the formation of small-scale baryonic structure and leave an imprint on the baryon acoustic oscillation (BAO) scale at low redshifts after reionization. This "streaming velocity" affects the post-reion...
