The Non-Parametric Model for Linking Galaxy Luminosity with Halo/Subhalo Mass: Are First Brightest Galaxies Special?
A. Vale, J. P. Ostriker
We revisit the longstanding question of whether first brightest cluster galaxies are statistically drawn from the same distribution as other cluster galaxies or are "special", usin…
The Non-Parametric Model for Linking Galaxy Luminosity with Halo/Subhalo Mass
A. Vale, J. P. Ostriker
We present a non-parametric, empirically based, model for associating galaxy luminosities with halo/subhalo masses, based on a self-consistent treatment of subhalo mass loss and th…
Linking halo mass to galaxy luminosity
A. Vale, J. P. Ostriker
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 estimat…
Linear perturbations in a universe with a cosmological constant
Antonio Vale, Jose' P. S. Lemos
There are now evidences that the cosmological constant has a non-zero positive value. Alternative scenarios to a pure cosmological constant model are provided by quintessence,…
