Simulating weak lensing on CMB maps
S. Basak, S. Prunet, K. Benabed
We present a fast, arbitrarily accurate method to simulate the effect of gravitational lensing of the Cosmic Microwave Background anisotropies and polarization fields by large scal…
Dark energy constraints and correlations with systematics from CFHTLS weak lensing, SNLS supernovae Ia and WMAP5
M. Kilbinger, K. Benabed, J. Guy +15
We combine measurements of weak gravitational lensing from the CFHTLS-Wide survey, supernovae Ia from CFHT SNLS and CMB anisotropies from WMAP5 to obtain joint constraints on cosmo…
Full-Sky Weak Lensing Simulation with 70 Billion Particles
Romain Teyssier, Sandrine Pires, Simon Prunet +7
We have performed a 70 billion dark-matter particles N-body simulation in a 2 Gpc periodic box, using the concordance, cosmological model as favored by the latest WMAP3 re…
Probing inflation with CMB polarization : weak lensing effect on the covariance of CMB spectra
Jonathan Rocher, Karim Benabed, Francois Bouchet
CMB anisotropies are modified by the weak lensing effect of intervening large scale structures on the photon path from the last scattering surface to the observer. This has to be a…
First cosmic shear results from the Canada-France-Hawaii Telescope Wide Synoptic Legacy Survey
H. Hoekstra, Y. Mellier, L. van Waerbeke +6
We present the first measurements of the weak gravitational lensing signal induced by the large scale mass distribution from data obtained as part of the ongoing Canada-France-Hawa…
The cosmic shear three-point functions
K. Benabed, R. Scoccimarro
We investigate the three-point functions of the weak lensing cosmic shear, using both analytic methods and numerical results from N-body simulations. The analytic model, an isolate…
Constraining Dark Energy Evolution with Gravitational Lensing by Large Scale Structures
Karim Benabed, Ludovic Van Waerbeke
We study the sensitivity of weak lensing by large scale structures to the evolution of dark energy. We explore a 2-parameters model of dark energy evolution, inspired by tracking q…
Cross-correlating CMB polarization with local large scale structures
K. Benabed, F. Bernardeau, L. Van Waerbeke
We study heterogeneous quantities that efficiently cross-correlate the lensing information encoded in CMB polarization and large-scale structures recovered from weak lensing galaxy…
Cosmic string lens effects on CMB polarization patterns
K. Benabed, F. Bernardeau
Extending the Kaiser-Stebbins mechanism we propose here a method for detecting relics of topological defects such as cosmic strings based on lens-induced small-scale B-type polariz…
