[Virtual Colloquium] Physics of the Intergalactic Medium During Cosmological Reionization

Anson D’Aloisio (UC Riverside)

January 14 @ 3:30 PM - 4:30 PM

When the first galaxies formed, their starlight likely reionized and heated the intergalactic hydrogen that had existed since recombination.   I will discuss some of the rich physics of the intergalactic medium during this reionization process.  In the past few years, there has been significant progress towards understanding reionization.  I will highlight this progress, including the possibility that we have already observed reionization’s tail end in the Lyman-alpha forest of high-redshift quasar spectra. I will also discuss future prospects for probing reionization with the 21cm radiation background and with high-redshift Lyman-alpha emitting galaxies.
