Hybrid inflation in the complex plane

Valerie Fiona Domcke, Kohei Kamada

Supersymmetric hybrid inflation is an exquisite framework to connect inflationary cosmology to particle physics at the scale of grand unification. Ending in a phase transition associated with spontaneous symmetry breaking, it can naturally explain the gene ...

A new framework for numerical simulations of structure formation

Alexey Boyarsky, Oleg Ruchayskiy, Matthieu Schaller, Claude Becker

The diversity of structures in the Universe (from the smallest galaxies to the largest superclusters) has formed under the pull of gravity from the tiny primordial perturbations that we see imprinted in the cosmic microwave background. A quantitative descr ...

Planck 2013 results. XIX. The integrated Sachs-Wolfe effect

Julien Lesgourgues, Slobodan Ilic, Fabio Finelli

Based on cosmic microwave background (CMB) maps from the 2013 Planck Mission data release, this paper presents the detection of the integrated Sachs-Wolfe (ISW) effect, that is, the correlation between the CMB and large-scale evolving gravitational potenti ...

LFI systematic uncertainties

Julien Lesgourgues, Fabio Finelli

We present the current estimate of instrumental and systematic effect uncertainties for the Planck-Low Frequency Instrument relevant to the first release of the Planck cosmological results. We give an overview of the main effects and of the tools and metho ...

Zodiacal emission

Xin Chen, Julien Lesgourgues, Fabio Finelli

The Planck satellite provides a set of all-sky maps at nine frequencies from 30 GHz to 857 GHz. Planets, minor bodies, and di ff use interplanetary dust emission (IPD) are all observed. The IPD can be separated from Galactic and other emissions because Pla ...

Constraints on primordial non-Gaussianity

Julien Lesgourgues, Fabio Finelli

The Planck nominal mission cosmic microwave background (CMB) maps yield unprecedented constraints on primordial non-Gaussianity (NG). Using three optimal bispectrum estimators, separable template-fitting (KSW), binned, and modal, we obtain consistent value ...

Fast and accurate CMB computations in non-flat FLRW universes

Julien Lesgourgues

We present a new method for calculating CMB anisotropies in a non-flat Friedmann universe, relying on a very stable algorithm for the calculation of hyperspherical Bessel functions, that can be pushed to arbitrary precision levels. We also introduce a new ...

Planck 2013 results. XXXI. Consistency of the Planck data

Julien Lesgourgues, Fabio Finelli

The Planck design and scanning strategy provide many levels of redundancy that can be exploited to provide tests of internal consistency. One of the most important is the comparison of the 70 GHz (amplifier) and 100 GHz (bolometer) channels. Based on diffe ...

The effective gravitational decoupling between dark matter and the CMB

Julien Lesgourgues, Luc Voruz

We present a detailed and self-contained analytical derivation of the evolution of sub-horizon cosmological perturbations before decoupling, based on previous work by S. Weinberg. These solutions are valid in the minimal Lambda CDM scenario, to first order ...
