Cosmological constraints with weak lensing peak counts and second-order statistics in a large-field survey

Austin Peel, Chieh-An Lin, Francois Lanusse +3

Peak statistics in weak lensing maps access the non-Gaussian information contained in the large-scale distribution of matter in the Universe. They are therefore a promising complem…

Resolving galaxy cluster gas properties at z~1 with XMM-Newton and Chandra

I. Bartalucci, M. Arnaud, G. W. Pratt +3

We present a pilot X-ray study of the five most massive ( $M_{500} > 5 \times 1 0^{14} M_{⊙}$ ), distant (z~1), galaxy clusters detected via the Sunyaev-Zeldovich effect. We optimal…

Nonstandard cosmologies from physics beyond the Standard model

M. Yu. Khlopov

The modern cosmology is based on inflationary models with baryosynthesis and dark matter/energy.It implies extension of particle symmetry beyond the Standard model. Studies of phys…

Forecasting performance of CMB experiments in the presence of complex foreground contaminations

Radek Stompor, Josquin Errard, Davide Poletti

We present a new, semi-analytic framework for estimating the level of residuals present in CMB maps derived from multi-frequency Cosmic Microwave Background (CMB) data and forecast…

Science with the space-based interferometer LISA. IV: Probing inflation with gravitational waves

Nicola Bartolo, Chiara Caprini, Valerie Domcke +11

We investigate the potential for the LISA space-based interferometer to detect the stochastic gravitational wave background produced from different mechanisms during inflation. Foc…

Metastable Dark Energy with Radioactive-like Decay

Arman Shafieloo, Dhiraj Kumar Hazra, Varun Sahni +1

We propose a new class of metastable dark energy (DE) phenomenological models in which the DE decay rate does not depend on external parameters such as the scale factor or the curv…

The effect of matter structure on the gravitational waveform

Camille Bonvin, Chiara Caprini, Riccardo Sturani +1

Third generation ground-based interferometers as well as the planned space-based interferometer LISA are expected to detect a plethora of gravitational wave signals from coalescing…

Are we living near the center of a local void?

Giulia Cusin, Cyril Pitrou, Jean-Philippe Uzan

The properties of the cosmic microwave background (CMB) temperature and polarisation anisotropies measured by a static, off-centered observer located in a local spherically symmetr…

The lensing and temperature imprints of voids on the Cosmic Microwave Background

Yan-Chuan Cai, Mark Neyrinck, Qingqing Mao +3

We have searched for the signature of cosmic voids in the CMB, in both the Planck temperature and lensing-convergence maps; voids should give decrements in both. We use zobov voids…

Non-parametric deprojection of NIKA SZ observations: Pressure distribution in the Planck-discovered cluster PSZ1 G045.85+57.71

F. Ruppin, R. Adam, B. Comis +38

The determination of the thermodynamic properties of clusters of galaxies at intermediate and high redshift can bring new insights into the formation of large-scale structures. It…

Search for low-mass WIMPs in a 0.6 kg day exposure of the DAMIC experiment at SNOLAB

A. Aguilar-Arevalo, D. Amidei, X. Bertou +35

We present results of a dark matter search performed with a 0.6 kg day exposure of the DAMIC experiment at the SNOLAB underground laboratory. We measure the energy spectrum of ioni…

First Detection of Cosmic Microwave Background Lensing and Lyman-α Forest Bispectrum

Cyrille Doux, Emmanuel Schaan, Eric Aubourg +4

We present the first detection of a correlation between the Lyman- $α$ forest and cosmic microwave background (CMB) lensing. For each Lyman- $α$ forest in SDSS-III/BOSS DR12, we corr…

Planck intermediate results. L. Evidence for spatial variation of the polarized thermal dust spectral energy distribution and implications for CMB $B$ -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…

II. Apples to apples $A^{2}$ : cluster selection functions for next-generation surveys

Begoña Ascaso, Simona Mei, Jim G. Bartlett +1

We present the cluster selection function for three of the largest next-generation stage-IV surveys in the optical and infrared: Euclid-Optimistic, Euclid-Pessimistic and the Large…

High-resolution tSZ cartography of clusters of galaxies with NIKA at the IRAM 30-m telescope

F. Mayet, R. Adam, A. Adane +41

The thermal Sunyaev-Zeldovich effect (tSZ) is a powerful probe to study clusters of galaxies and is complementary with respect to X-ray, lensing or optical observations. Previous a…
