Cosmological parameters after WMAP5: forecasts for Planck and future galaxy surveys
L. P. L. Colombo, E. Pierpaoli, J. R. Pritchard
The Planck satellite is expected to improve the measurement of most cosmological parameters by several factors with respect to current WMAP results. The actual performance may depe…
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…
Reconstructing mass profiles of simulated galaxy clusters by combining Sunyaev-Zeldovich and X-ray images
S. Ameglio, S. Borgani, E. Pierpaoli +3
We present a method to recover mass profiles of galaxy clusters by combining data on thermal Sunyaev-Zeldovich (tSZ) and X-ray imaging, thereby avoiding to use any information on X…
CMBPol Mission Concept Study: Probing Inflation with CMB Polarization
Daniel Baumann, Mark G. Jackson, Peter Adshead +56
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…
CMBPol Mission Concept Study: Prospects for polarized foreground removal
J. Dunkley, A. Amblard, C. Baccigalupi +28
In this report we discuss the impact of polarized foregrounds on a future CMBPol satellite mission. We review our current knowledge of Galactic polarized emission at microwave freq…
Constraining massive neutrinos using cosmological 21 cm observations
Jonathan R. Pritchard, Elena Pierpaoli
Observations of neutrino oscillations show that neutrinos have mass. However, the best constraints on this mass currently come from cosmology, via measurements of the cosmic microw…
