Failures of Halofit model for computation of Fisher Matrices
P. Reimberg, F. Bernardeau, T. Nishimichi +1
We use a simple cosmological model with two parameters to illustrate the impact of using Halofit on error forecast based on Fisher information matrix for a $h^{-3} Gpc…

Encircling the dark: constraining dark energy via cosmic density in spheres
S. Codis, C. Pichon, F. Bernardeau +2
The recently published analytic probability density function for the mildly non-linear cosmic density field within spherical cells is used to build a simple but accurate maximum li…
