Tomographic weak lensing bispectrum: a thorough analysis towards the next generation of galaxy surveys
Matteo Rizzato, Karim Benabed, Francis Bernardeau +1
We address key points for an efficient implementation of likelihood codes for modern weak lensing large-scale structure surveys. Specifically, we focus on the joint weak lensing co…
Secondary CMB anisotropies from magnetized halos --I: Power spectra of the Faraday rotation angle and conversion rate
Nadège Lemarchand, Julien Grain, Guillaume Hurier +2
Magnetized plasmas within halos of galaxies leave their footprint on the polarized anisotropies of the cosmic microwave background. The two dominant effects for astrophysical halos…
Fast and easy super-sample covariance of large scale structure observables
Fabien Lacasa, Julien Grain
We present a numerically cheap approximation to super-sample covariance (SSC) of large scale structure cosmological probes, first in the case of angular power spectra. It necessita…
Dark Energy Survey Year 1 Results: Measurement of the Galaxy Angular Power Spectrum
H. Camacho, N. Kokron, F. Andrade-Oliveira +73
We use data from the first-year (Y1) observations of the DES collaboration to measure the galaxy angular power spectrum (APS), and search for its BAO feature using a template-fitti…
Survey geometry and the internal consistency of recent cosmic shear measurements
M. A. Troxel, E. Krause, C. Chang +76
We explore the impact of an update to the typical approximation for the shape noise term in the analytic covariance matrix for cosmic shear experiments that assumes the absence of…
