Abstract

The large cross section of the Lyman alpha line makes it a sensitive probe of the ionization state of the intergalactic medium IGM Hence the observability of Lya emission from galaxies is one of the most promising near term probes of the as yet uncharted Epoch of Reionization EoR Unfortunately its utility is hampered by a lack of understanding of the intrinsic emission as well as our inability to accurately model the IGM on the required range of scales I will discuss how recent advances in multi tiered EoR modelling can be applied to interpreting observations of: i the clustering of high z Lyman alpha emitters LAEs and ii the correlation of LAEs with the cosmic 21cm field
