Colloquium by Martin G. Haehnelt (University of Cambridge)

Probing reionization with Lyman-alpha and 21cm emission/absorption

Abstract:

I will give an overview of recent constraints on reionization fromLyman-alpha and 21cm emission/absorption with special emphasis on the implications of the rather large scales (>=50cMpc) of observed large opacity fluctuations at z>5.5 for the nature of the sources of ionising radiation.
