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 ...

Planck 2013 results. XVIII. The gravitational lensing-infrared background correlation

Julien Lesgourgues, Fabio Finelli

The multi-frequency capability of the Planck satellite provides information both on the integrated history of star formation (via the cosmic infrared background, or CIB) and on the distribution of dark matter (via the lensing effect on the cosmic microwave ...

Planck 2013 results. XII. Diffuse component separation

Julien Lesgourgues, Xin Chen, Fabio Finelli

Planck has produced detailed all-sky observations over nine frequency bands between 30 and 857 GHz. These observations allow robust reconstruction of the primordial cosmic microwave background (CMB) temperature fluctuations over nearly the full sky, as wel ...

THE Ly alpha REFERENCE SAMPLE. I. SURVEY OUTLINE AND FIRST RESULTS FOR MARKARIAN 259

Hakim Atek

The Ly alpha Reference Sample (LARS) is a substantial program with the Hubble Space Telescope (HST) that provides a sample of local universe laboratory galaxies in which to study the detailed astrophysics of the visibility and strength of the Ly alpha line ...

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 ...

Planck 2013 results. XXI. Power spectrum and high-order statistics of the Planck all-sky Compton parameter map

Julien Lesgourgues, Fabio Finelli

We have constructed the first all-sky map of the thermal Sunyaev-Zeldovich (tSZ) effect by applying specifically tailored component separation algorithms to the 100 to 857 GHz frequency channel maps from the Planck survey. This map shows an obvious galaxy ...

Planck 2013 results. XVI. Cosmological parameters

Julien Lesgourgues, Xin Chen, Fabio Finelli, Jan Hamann

This paper presents the first cosmological results based on Planck measurements of the cosmic microwave background (CMB) temperature and lensing-potential power spectra. We find that the Planck spectra at high multipoles (l greater than or similar to 40) a ...

Mass and magnification maps for the Hubble Space Telescope Frontier Fields clusters: implications for high-redshift studies

Jean-Paul Richard Kneib, Hakim Atek, Benjamin Yvan Alexandre Clement, Mathilde Jauzac, Johan Richard

Extending over three Hubble Space Telescope (HST) cycles, the Hubble Frontier Fields (HFF) initiative constitutes the largest commitment ever of HST time to the exploration of the distant Universe via gravitational lensing by massive galaxy clusters. Here, ...

Removal of two large-scale cosmic microwave background anomalies after subtraction of the integrated Sachs-Wolfe effect

Anaïs Marie Rassat, Jean-Luc Starck

Context. Although there is currently a debate over the significance of the claimed large-scale anomalies in the cosmic microwave background (CMB), their existence is not totally dismissed. In parallel to the debate over their statistical significance, rece ...

Low-l CMB analysis and inpainting

Anaïs Marie Rassat, Jean-Luc Starck

Reconstructing the cosmic microwave background (CMB) in the Galactic plane is extremely difficult due to the dominant foreground emissions such as dust, free-free or synchrotron. For cosmological studies, the standard approach consists in masking this area ...

COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XI. Techniques for time delay measurement in presence of microlensing

Frédéric Courbin, Georges Meylan, Malte Tewes

Measuring time delays between the multiple images of gravitationally lensed quasars is now recognized as a competitive way to constrain the cosmological parameters, and it is complementary with other cosmological probes. This requires long and well sampled ...

ORIGIN: metal creation and evolution from the cosmic dawn

Mikhail Chapochnikov, Alexey Boyarsky, Oleg Ruchayskiy, Douglas Cameron Watson, Simone Campana

ORIGIN is a proposal for the M3 mission call of ESA aimed at the study of metal creation from the epoch of cosmic dawn. Using high-spectral resolution in the soft X-ray band, ORIGIN will be able to identify the physical conditions of all abundant elements ...
