Planck 2013 results. I. Overview of products and scientific results
The European Space Agency’s Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14 May 2009 and has been scanning the microwave and submillimetre skyExpand
An improved map of the Galactic Faraday sky
We aim to summarize the current state of knowledge regarding Galactic Faraday rotation in an all-sky map of the Galactic Faraday depth. For this we have assembled the most extensive catalog ofExpand
Hydrodynamical N-body simulations of coupled dark energy cosmologies
If the accelerated expansion of the Universe at the present epoch is driven by a dark energy scalar field, there may well be a non-trivial coupling between the dark energy and the cold dark matterExpand
Early dark energy cosmologies
We propose a novel parameterization of the dark energy density. It is particularly well suited to describe a non-negligible contribution of dark energy at early times and contains only threeExpand
Impact of three years of data from the Wilkinson Microwave Anisotropy Probe on cosmological models with dynamical dark energy
The first three years of observation of the Wilkinson Microwave Anisotropy Probe (WMAP) have provided the most precise data on the anisotropies of the cosmic microwave background (CMB) to date. WeExpand
Probing magnetic helicity with synchrotron radiation and Faraday rotation
We present a first application of the recently proposed LITMUS test for magnetic helicity, as well as a thorough study of its applicability under different circumstances. In order to apply this testExpand
Planck early results. III. First assessment of the Low Frequency
The Planck High Frequency Instrument (HFI) is designed to measure the temperature and polarization anisotropies of the Cosmic Microwave Background and galactic foregrounds in six wide bands centeredExpand
Averaging Robertson-Walker cosmologies
The cosmological backreaction arises when one directly averages the Einstein equations to recover an effective Robertson-Walker cosmology, rather than assuming a background a priori. While usuallyExpand
Neutrino clustering in growing neutrino quintessence
Abstract A growing neutrino mass can stop the dynamical evolution of a dark energy scalar field, thus explaining the “why now” problem. We show that such models lead to a substantial neutrinoExpand
Planck early results. V. The Low Frequency Instrument data processing
We describe the processing of data from the Low Frequency Instrument (LFI) used in production of the Planck Early Release Compact Source Catalogue (ERCSC). In particular, we discuss the stepsExpand
