CMBPol Mission Concept Study: Foreground Science Knowledge and Prospects
A. A. Fraisse, J. -A. C. Brown, G. Dobler +10
We report on our knowledge of Galactic foregrounds, as well as on how a CMB satellite mission aiming at detecting a primordial B-mode signal (CMBPol) will contribute to improving i…
CMBPol Mission Concept Study: A Mission to Map our Origins
Daniel Baumann, Asantha Cooray, Scott Dodelson +7
Quantum mechanical metric fluctuations during an early inflationary phase of the universe leave a characteristic imprint in the polarization of the cosmic microwave background (CMB…
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…
Polarized Far-Infrared and Submillimeter Emission from Interstellar Dust
Bruce T. Draine, Aurélien A. Fraisse
Polarized far-infrared and submillimeter emission is calculated for models of nonspherical dust grains that are constrained to reproduce the observed wavelength-dependent extinctio…
Small-Angle CMB Temperature Anisotropies Induced by Cosmic Strings
Aurélien A. Fraisse, Christophe Ringeval, David N. Spergel +1
We use Nambu-Goto numerical simulations to compute the cosmic microwave background (CMB) temperature anisotropies induced at arcminute angular scales by a network of cosmic strings…
Limits on Defects Formation and Hybrid Inflationary Models with Three-Year WMAP Observations
Aurélien A. Fraisse
We confront the predicted effects of hybrid inflationary models on the Cosmic Microwave Background (CMB) with three years of Wilkinson Microwave Anisotropy Probe (WMAP) observation…
