A 7 deg(2) survey for galaxy-scale gravitational lenses with the HST imaging archive(star)

Frédéric Courbin, Georges Meylan, Ravindra Pawase

We present the results of a visual search for galaxy-scale gravitational lenses in similar to 7 deg(2) of Hubble Space Telescope (HST) images. The data set comprises the whole imaging data ever taken with the Advanced Camera for Surveys (ACS) in the filter ...

Planck 2013 results. XXII. Constraints on inflation

Jean-Luc Starck, Julien Lesgourgues, Fabio Finelli, Jan Hamann

We analyse the implications of the Planck data for cosmic inflation. The Planck nominal mission temperature anisotropy measurements, combined with the WMAP large-angle polarization, constrain the scalar spectral index to be n(s) = 0.9603 +/- 0:0073, ruling ...

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 ...

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 ...

A superconducting diplexer for cosmic microwave background experiments

Juan Ramon Mosig, Mohammadreza Madi, Michael Mattes

Cosmic microwave background (CMB) studies require observations in several frequency bands simultaneously. For example, the detection of clusters of remote galaxies can be performed by comparing CMB photon fluxes at different frequencies, using the spectral ...

Planck 2013 results. IX. HFI spectral response

Xin Chen, Julien Lesgourgues, Fabio Finelli

The Planck High Frequency Instrument (HFI) spectral response was determined through a series of ground based tests conducted with the HFI focal plane in a cryogenic environment prior to launch. The main goal of the spectral transmission tests was to measur ...

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 ...

CMB photons shedding light on dark matter

Julien Lesgourgues, Benjamin Audren, Gaëlle Giesen

The annihilation or decay of Dark Matter (DM) particles could affect the thermal history of the universe and leave an observable signature in Cosmic Microwave Background (CMB) anisotropies. We update constraints on the annihilation rate of DM particles in ...
