The impact and response of mini-haloes and the interhalo medium on cosmic reionization Open
An ionization front (I-front) that propagates through an inhomogeneous medium is slowed down by self-shielding and recombinations. We perform cosmological radiation hydrodynamics simulations of the I-front propagation during the epoch of c…
