We forecast the main cosmological parameter constraints achievable with the CORE space mission which is dedicated to mapping the polarisation of the Cosmic Microwave Background (CM…
Power law cosmology model comparison with CMB scale information
Isaac Tutusaus, Brahim Lamine, Alain Blanchard +14
Despite the ability of the cosmological concordance model (CDM) to describe the cosmological observations exceedingly well, power law expansion of the Universe scale radius, $R(…
Non-Gaussianity in two-field inflation beyond the slow-roll approximation
Gabriel Jung, Bartjan van Tent
We use the long-wavelength formalism to investigate the level of bispectral non-Gaussianity produced in two-field inflation models with standard kinetic terms. Even though the Plan…
Statistical simulations of the dust foreground to CMB polarization
Flavien Vansyngel, François Boulanger, Tuhin Ghosh +6
The characterization of the dust polarization foreground to the Cosmic Microwave Background (CMB) is a necessary step towards the detection of the B-mode signal associated with pri…
Primordial Nucleosynthesis
Alain Coc
Primordial or big bang nucleosynthesis (BBN) is now a parameter free theory whose predictions are in good overall agreement with observations. However, the 7Li calculated abundance…
ATCA observations of the MACS-Planck Radio Halo Cluster Project - I. New detection of a radio halo in PLCK G285.0-23.7
Gerardo Martinez Aviles, Chiara Ferrari, Melanie Johnston-Hollitt +12
We investigate the possible presence of diffuse radio emission in the intermediate redshift, massive cluster PLCK G285.0-23.7 (z=0.39, M_500 = 8.39 x 10^(14) M_Sun). Our 16cm-band…
Weakening Gravity on Redshift-Survey Scales with Kinetic Matter Mixing
Guido D'Amico, Zhiqi Huang, Michele Mancarella +1
We explore general scalar-tensor models in the presence of a kinetic mixing between matter and the scalar field, which we call Kinetic Matter Mixing. In the frame where gravity is…
Cosmology with the CMB temperature-polarization correlation
F. Couchot, S. Henrot-Versillé, O. Perdereau +4
We demonstrate that the cosmic microwave background (CMB) temperature-polarization cross-correlation provides accurate and robust constraints on cosmological parameters. We compare…
QuickPol: Fast calculation of effective beam matrices for CMB polarization
Eric Hivon, Sylvain Mottet, Nicolas Ponthieu
Current and planned observations of the cosmic microwave background (CMB) polarization anisotropies, with their ever increasing number of detectors, have reached a potential accura…

We report on a dark matter search for a Weakly Interacting Massive Particle (WIMP) in the mass range with the EDELWEISS-III experiment. A 2D prof…
Planck intermediate results. L. Evidence for spatial variation of the polarized thermal dust spectral energy distribution and implications for CMB -mode analysis
Planck Collaboration, N. Aghanim, M. Ashdown +156
The characterization of the Galactic foregrounds has been shown to be the main obstacle in the challenging quest to detect primordial B-modes in the polarized microwave sky. We mak…
