Detecting and studying the reionization process is challenging but multiple avenues have been pursued. This reionization was driven by the formation...

reionization was not uniformly spread through the IGM. Simulations have shown that low-mass galaxies could have initially contributed to reionization...

Despite being reionized, the universe remained largely transparent during reionization due how sparse the intergalactic medium was. Reionization gradually...

ordinary matter particles fall into the structures created by dark matter. Reionization begins: smaller (stars) and larger non-linear structures (quasars) begin...

mechanism for reionization to occur as galaxies form. Despite this, current theories suggest that quasars were not the primary source of reionization; the primary...

Epoch of Reionization Array (HERA) is a radio telescope dedicated to observing large scale structure during and prior to the epoch of reionization. HERA...
