CMBPol Mission Concept Study: Reionization Science with the Cosmic Microwave Background
Matias Zaldarriaga, Loris Colombo, Eiichiro Komatsu +6
We summarize existing constraints on the epoch of reionization and discuss the observational probes that are sensitive to the process. We focus on the role large scale polarization…
Falsifying Paradigms for Cosmic Acceleration
Michael J. Mortonson, Wayne Hu, Dragan Huterer
Consistency relations between growth of structure and expansion history observables exist for any physical explanation of cosmic acceleration, be it a cosmological constant, scalar…
Reionization constraints from five-year WMAP data
Michael J. Mortonson, Wayne Hu
We study the constraints on reionization from five years of WMAP data, parametrizing the evolution of the average fraction of ionized hydrogen with principal components that provid…
