While second and higher order correlations of the light distribution have received extensive study, the lowest order probability distribution function (PDF)—the probability that a unit volume of space will emit a given amount of light—has received very little attention. We estimate this function with the aid of hydrodynamic simulations of the ΛCDM model, finding it significantly different from the mass density PDF, and not simply related to it by linear bias or any of the other prescriptions… Expand

The VIMOS VLT deep survey: testing the gravitational instability paradigm at z ~ 1
We have reconstructed the three-dimensional density fluctuation maps to z˜ 1.5 using the distribution of galaxies observed in the VVDS-Deep survey. We use this overdensity field to measure theExpand
Light-to-Mass Variations with Environment
Large and well-defined variations exist between the distribution of mass and the light of stars on extragalactic scales. Mass concentrations in the range 1012-1013 M☉ manifest the most light per unitExpand

Peculiar velocities throughout the region of the Local Supercluster are reconstructed by two different orbit-retracing methods. The requirement of optimal correlation between the radial components ofExpand
Linking halo mass to galaxy luminosity
In this paper we present a new, essentially empirical, model for the relation between the mass of a dark matter halo/subhalo and the luminosity of a galaxy hosted in it. To estimate this, we replaceExpand
