Springel, Volker, White, Simon D. M.
A new method is presented to obtain a non-parametric maximum likelihood estimate of the luminosity function and the selection function of a flux limited redshift survey. The method parameterizes the...
The Physical Origin of Galaxy Scaling Relations (1997)
A standard paradigm is now available for the recent evolution (z < 10) of structure on galactic and larger scales. Most of the matter is assumed to be dark and dissipationless and to cluster...
Anisotropies in the Distribution of Satellite Galaxies (1996)
Zaritsky, Dennis, Smith, Rodney, Frenk, Carlos S., White, Simon D. M.
We find that satellites of isolated disk galaxies at projected radii between 300 and 500 kpc are distributed asymmetrically about the parent galaxy and aligned preferentially with the disk minor...
More Satellites of Spiral Galaxies (1996)
Zaritsky, Dennis, Smith, Rodney, Frenk, Carlos, White, Simon D. M.
We present a revised and expanded catalog of satellite galaxies of a set of isolated spiral galaxies similar in luminosity to the Milky Way. This sample of 115 satellites, 69 of which were discovered...
A Universal Density Profile from Hierarchical Clustering (1996)
Navarro, Julio F., Frenk, Carlos S., White, Simon D. M.
We use high-resolution N-body simulations to study the equilibrium density profiles of dark matter halos in hierarchically clustering universes. We find that all such profiles have the same shape,...
Dekel, Avishai, Burstein, David, White, Simon D. M.
We were asked to debate the value of the cosmological mass-density parameter Omega. Is Omega_m=1 in accordance with the simplest model? Is Omega_m much smaller as indicated by some observations?...
Dark halo mergers and the formation of a universal profile (1996)
We argue that a universal density profile for dark matter halos arises as a natural consequence of hierarchical structure formation. It is a fixed point in the process of repeated mergers. We present...
Two--body heating in numerical galaxy formation experiments (1996)
Steinmetz, Matthias, White, Simon D. M.
We show that discreteness effects related to classical two-body relaxation produce spurious heating of the gaseous component in numerical simulations of galaxy formation. A simple analytic model...
Large-scale structure at high redshift (1996)
I discuss and illustrate the development of large-scale structure in the Universe, emphasising in particular the physical processes and cosmological parameters that most influence the observationally...
Detection of Strong Evolution in the Population of Early-Type Galaxies (1996)
Kauffmann, Guinevere, Charlot, Stephane, White, Simon D. M.
The standard picture holds that giant elliptical galaxies formed in a single burst at high redshift. Aging of their stellar populations subsequently caused them to fade and become redder. The...
The Nature and Observability of Protogalaxies (1996)
I discuss recent theoretical work on the formation and evolution of galaxies paying particular attention to the ability of current models to make detailed comparisons with observations of the galaxy...
The Structure and Dynamical Evolution of Dark Matter Halos (1996)
Tormen, Giuseppe, Bouchet, Francois R., White, Simon D. M.
(Shortened) We use N-body simulations to investigate the structure and dynamical evolution of dark matter halos in galaxy clusters. Our sample consists of nine massive halos from an EdS universe with...
Hierarchical Clustering and Galaxy Formation (1996)
I review the theory of hierarchical clustering, starting with an historical overview and moving on to a discussion of those aspects of dissipationless clustering under gravity which are most relevant...
Violent Relaxation in Hierarchical Clustering (1996)
The term ``violent relaxation'' was coined by Donald Lynden-Bell as a memorable oxymoron describing how a stellar dynamical system relaxes from a chaotic initial state to a quasi-equilibrium. His...
The Structure of Cold Dark Matter Halos (1995)
Navarro, Julio F., Frenk, Carlos S., White, Simon D. M.
We use N-body simulations to investigate the structure of dark halos in the standard Cold Dark Matter cosmogony. Halos are excised from simulations of cosmologically representative regions and are...
Formation and Evolution of Galaxies: Les Houches Lectures (1994)
This is a set of lecture notes based on the lectures on the formation and evolution of galaxies which were given by S. White at Les Houches in August 1993. This postscript file does not contain the...
The Assembly of Galaxies in a Hierarchically Clustering Universe (1994)
Navarro, Julio F., Frenk, Carlos S., White, Simon D. M.
We study the formation of galaxies by using $N$-body/hydrodynamics simulations to investigate how baryons collect at the centre of dark matter halos. We treat the dark matter as a collisionless fluid...
Simulations of X-ray Clusters (1994)
Navarro, Julio F., Frenk, Carlos S., White, Simon D. M.
We present simulations of the formation and evolution of galaxy clusters in the Cold Dark Matter cosmogony. Clusters with a wide range of mass were selected from previous N-body models, and were...
