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.
