Modeling Intrinsic Galaxy Alignment in the MICE Simulation

Autor: Hoffmann, Kai, Secco, Lucas F., Blazek, Jonathan, Crocce, Martin, Tallada-Crespí, Pau, Samuroff, Simon, Prat, Judit, Carretero, Jorge, Fosalba, Pablo, Gaztanaga, Enrique, Castander, Francisco J.

The intrinsic alignment (IA) of galaxies is potentially a major limitation in deriving cosmological constraints from weak lensing surveys. In order to investigate this effect we assign intrinsic shapes and orientations to galaxies in the light-cone o

We study a phenomenological class of models where dark matter converts to dark radiation in the low redshift epoch. This class of models, dubbed DMDR, characterizes the evolution of comoving dark matter density with two extra parameters, and may be a

Fourier analysis of multi-tracer cosmological surveys

Autor: Abramo, L. Raul, Secco, Lucas F., Loureiro, Arthur

We present optimal quadratic estimators for the Fourier analysis of cosmological surveys that detect several different types of tracers of large-scale structure. Our estimators can be used to simultaneously fit the matter power spectrum and the biase

We examine the cosmological constraining power from two cross-correlation probes between galaxy and cosmic microwave background (CMB) surveys: the cross-correlation of lens galaxy density with CMB lensing convergence 〈δgκCMB〉, and source galaxy
