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…
Needlet Detection of Features in WMAP CMB Sky and the Impact on Anisotropies and Hemispherical Asymmetries
Davide Pietrobon, Alexandre Amblard, Amedeo Balbi +3
We apply spherical needlets to the Wilkinson Microwave Anisotropy Probe 5-year cosmic microwave background (CMB) dataset, to search for imprints of non-isotropic features in the CM…
Implications of Two Type Ia Supernova Populations for Cosmological Measurements
Devdeep Sarkar, Alexandre Amblard, Asantha Cooray +1
Recent work suggests that Type Ia supernovae (SNe) are composed of two distinct populations: prompt and delayed. By explicitly incorporating properties of host galaxies, it may be…
Impact of Point Source Clustering on Cosmological Parameters with CMB Anisotropies
Paolo Serra, Asantha Cooray, Alexandre Amblard +2
The faint radio point sources that are unresolved in cosmic microwave background (CMB) anisotropy maps are likely to be a biased tracer of the large-scale structure dark matter dis…
Lensing and Supernovae: Quantifying The Bias on the Dark Energy Equation of State
Devdeep Sarkar, Alexandre Amblard, Daniel E. Holz +1
The gravitational magnification and demagnification of Type Ia supernovae (SNe) modify their positions on the Hubble diagram, shifting the distance estimates from the underlying lu…
Beyond Two Dark Energy Parameters
Devdeep Sarkar, Scott Sullivan, Shahab Joudaki +3
Our ignorance of the dark energy is generally described by a two-parameter equation of state. In these approaches a particular {\it ad hoc} functional form is assumed, and only two…
Cosmic Reionization and the 21-cm signal: Comparison between an analytical model and a simulation
Mario G. Santos, Alexandre Amblard, Jonathan Pritchard +3
We measure several properties of the reionization process and the corresponding low-frequency 21-cm signal associated with the neutral hydrogen distribution, using a large volume,…
Anisotropy Studies of the Unresolved Far-infrared Background
Alexandre Amblard, Asantha Cooray
Dusty, starforming galaxies and active galactic nuclei that contribute to the integrated background intensity at far-infrared wavelengths trace the large-scale structure. Below the…
Search for Gravitational Waves in the CMB After WMAP3: Foreground Confusion and The Optimal Frequency Coverage for Foreground Minimization
Alexandre Amblard, Asantha Cooray, Manoj Kaplinghat
B-modes of Cosmic Microwave Background (CMB) polarization can be created by a primordial gravitational wave background. If this background was created by Inflation, then the amplit…
Archeops In-flight Performance, Data Processing and Map Making
J. F. Macias-Perez, G. Lagache, B. Maffei +69
Archeops is a balloon--borne experiment widely inspired by the Planck satellite and by its High Frequency Instrument (HFI). It is mainly dedicated to measure the Cosmic Microwave B…
Temperature and polarization angular power spectra of Galactic dust radiation at 353 GHz as measured by Archeops
N. Ponthieu, J. F. Macías-Pérez, M. Tristram +47
We present the first measurement of temperature and polarization angular power spectra of the diffuse emission of Galactic dust at 353 GHz as seen by Archeops on 20% of the sky. Th…

M. Tristram, G. Patanchon, J. F. Macias-Perez +47
We present improved results on the measurement of the angular power spectrum of the Cosmic Microwave Background (CMB) temperature anisotropies using the data from the last Archeops…
Sunyaev Zel'dovich polarization simulation
A. Amblard, M. White
Compton scattering of Cosmic Microwave Background (CMB) photons on galaxy cluster electrons produces a linear polarization, which contains some information on the local quadrupole…
Weak Lensing of the CMB by Large-Scale Structure
Alexandre Amblard, Chris Vale, Martin White
Several recent papers have studied lensing of the CMB by large-scale structures, which probes the projected matter distribution from to . This interest is motiv…
Cluster Lensing of the CMB
Chris Vale, Alexandre Amblard, Martin White
We investigate what the lensing information contained in high resolution, low noise CMB temperature maps can teach us about cluster mass profiles. We create lensing fields and Suny…
Noise power spectrum estimation and fast map making for CMB experiments
Alexandre Amblard, Jean-Christophe Hamilton
We present a method designed to estimate the noise power spectrum in the time domain for CMB experiments. The noise power spectrum is extracted from the time ordered data avoiding…
First Detection of Polarization of the Submillimetre Diffuse Galactic Dust Emission by Archeops
