Strongest model-independent bound on the lifetime of Dark Matter

Julien Lesgourgues, Benjamin Audren

Dark Matter is essential for structured formation in the late Universe so it must be stable on cosmological time scales. But how stable exactly? Only assuming decays into relativistic on particles, we report an otherwise model independent bound on the life ...

Planck 2013 results. XX. Cosmology from Sunyaev-Zeldovich cluster counts

Julien Lesgourgues, Fabio Finelli

We present constraints on cosmological parameters using number counts as a function of redshift for a sub-sample of 189 galaxy clusters from the Planck SZ (PSZ) catalogue. The PSZ is selected through the signature of the Sunyaev-Zeldovich (SZ) effect, and ...

Planck 2013 results. XXIII. Isotropy and statistics of the CMB

Julien Lesgourgues, Jason Douglas McEwen, Ji Hyun Kim, Fabio Finelli

The two fundamental assumptions of the standard cosmological model - that the initial fluctuations are statistically isotropic and Gaussian - are rigorously tested using maps of the cosmic microwave background (CMB) anisotropy from the Planck satellite. Th ...

Planck CMB nomalies: astrophysical and cosmological secondary effects and the curse of masking

Anaïs Marie Rassat

Large-scale anomalies have been reported in CMB data with both WMAP and Planck data. These could be due to foreground residuals and or systematic effects, though their confirmation with Planck data suggests they are not due to a problem in the WMAP or Plan ...

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 ...

Joint Planck and WMAP CMB map reconstruction

Jean-Luc Starck, Anaïs Marie Rassat

We present a novel estimate of the cosmological microwave background (CMB) map by combining the two latest full-sky microwave surveys: WMAP nine-year and Planck PR1. The joint processing benefits from a recently introduced component separation method coine ...

Conservative constraints on early cosmology with MONTE PYTHON

Julien Lesgourgues, Benjamin Audren

Models for the latest stages of the cosmological evolution rely on a less solid theoretical and observational ground than the description of earlier stages like BBN and recombination. As suggested in a previous work by Vonlanthen et al., it is possible to ...

Two Accurate Time-Delay Distances From Strong Lensing: Implications For Cosmology

Frédéric Courbin, Georges Meylan, Malte Tewes

Strong gravitational lenses with measured time delays between the multiple images and models of the lens mass distribution allow a one-step determination of the time-delay distance, and thus a measure of cosmological parameters. We present a blind analysis ...
