"Shedding Lyman Alpha Light on Cosmological Reionization" Intergalactic hydrogen, which first became neutral near redshift 1100, was re-ionized somewhere between redshift 6 and 15. This marked the first global impact that gravitationally bound objects (stars and/or black holes) had on the universe around them, and also the last time that most hydrogen atoms did anything noteworthy. Understanding this reionization process in detail is now a frontier of observational cosmology.
Lyman alpha photons are a powerful tool for studying reionization. They interact strongly with neutral hydrogen, so that neutral intergalactic gas acts to hide Lyman alpha light from our instruments. Arizona State University host: Steve Finkelstein |
