Redshift Space Effects: 2) Light Cone Effect 3D power spectrum from 21cm observations: one axis is the LOS axis → Evolving signal. Limits the band width over which 3D power spectrum can be extracted. Barkana & Loeb (2006); Datta, GM, et al. (2011) 26 April 2012 EoR2012, Strasbourg 24
Telling Different Scenarios Apart How well can 21cm observations tell different source scenarios apart? Since the amount of escaping ionizing photons depends on the combination of IMF, f SF and f esc, esc, 21cm measurements alone alone cannot distinguish these. Can 21cm measurements tell different source populations apart? 26 April 2012 EoR2012, Strasbourg 25
