Kauffmann, Guinevere, Charlot, Stephane, Balogh, Michael L.

We explore a model in which efficient star formation in galaxies is triggered by merging satellites. We show that the merger/interaction rates predicted by hierarchical galaxy formation models depend...

Non-linear Stochastic Galaxy Biasing in Cosmological Simulations (2001)

Rachel Somerville Gerard, Gerard Lemson, Yair Sigad, Avishai Dekel, Guinevere Kauffmann

We study the biasing relation between dark-matter halos or galaxies and the underlying mass distribution, using cosmological N-body simulations in which galaxies are modelled via semi-analytic...

Populating a cluster of galaxies - I. Results at z=0 (2000)

Springel, Volker, White, Simon, Tormen, Giuseppe, Kauffmann, Guinevere

We simulate the assembly of a massive rich cluster and the formation of its constituent galaxies in a flat, low-density universe. Our most accurate model follows the collapse, the star-formation...

The correlation between black hole mass and bulge velocity dispersion in hierarchical galaxy formation models (2000)

Haehnelt, Martin G., Kauffmann, Guinevere

Recent work has demonstrated that there is a tight correlation between the mass of a black hole and the velocity dispersion of the bulge of its host galaxy. We show that the model of Kauffmann &...

The Spatial and Kinematic Distributions of Cluster Galaxies in a LCDM Universe -- Comparison with Observations (2000)

Diaferio, Antonaldo, Kauffmann, Guinevere, Balogh, Michael L., White, Simon D. M., Schade, David, Ellingson, Erica

We combine dissipationless N-body simulations and semi-analytic models of galaxy formation to study the spatial and kinematic distributions of cluster galaxies in a LCDM cosmology. We investigate how...

The formation and evolution of supermassive black holes and their host galaxies (1999)

Haehnelt, Martin G., Kauffmann, Guinevere

We discuss constraints on the assembly history of supermassive black holes from the observed remnant black holes in nearby galaxies and from the emission caused by accretion onto these black holes....

A Unified Model for the Evolution of Galaxies and Quasars (1999)

Kauffmann, Guinevere, Haehnelt, Martin

We incorporate a simple scheme for the growth of supermassive black holes into semi-analytic models that follow the formation and evolution of galaxies in a cold dark matter dominated Universe. We...

Probing Star Formation Timescales in Elliptical Galaxies (1999)

Thomas, Daniel, Kauffmann, Guinevere

In models of galaxy formation in a hierarchical Universe, elliptical galaxies form through the merging of smaller disk systems. These models yield a number of testable predictions if reliable...

Clustering of Galaxies in a Hierarchical Universe: III. Mock Redshift Surveys (1998)

Diaferio, Antonaldo, Kauffmann, Guinevere, Colberg, Joerg M., White, Simon D. M.

This is the third paper in a series which combines N-body simulations and semi-analytic modelling to provide a fully spatially resolved simulation of the galaxy formation and clustering processes....

Evolution of Elliptical Galaxies in a Hierarchical Universe (1998)

Kauffmann, Guinevere, Charlot, Stephane

In hierarchical models of galaxy formation, ellipticals form from the merging of disk galaxies drawn together by gravity as their surrounding dark halos coalesce. Using semi-analytic techniques, we...

Clustering of Galaxies in a Hierarchical Universe: II. Evolution to High Redshift (1998)

Kauffmann, Guinevere, Colberg, Joerg M., Diaferio, Antonaldo, White, Simon D. M.

In hierarchical cosmologies the evolution of galaxy clustering depends both on cosmological quantities such as Omega and Lambda, which determine how dark matter halos form and evolve, and on the...

Clustering of Galaxies in a Hierarchical Universe: I. Methods and Results at z=0 (1998)

Kauffmann, Guinevere, Colberg, Joerg M., Diaferio, Antonaldo, White, Simon D. M.

We introduce a new technique for following the formation and evolution of galaxies in cosmological N-body simulations. Dissipationless simulations are used to track the formation and merging of dark...

The K-band luminosity function at z=1: a powerful constraint on galaxy formation theory (1998)

Kauffmann, Guinevere, Charlot, Stephane

There are two major approaches to modelling galaxy evolution. The traditional view is that the most massive galaxies were assembled early and have evolved with steeply declining star formation rates...

Environmental Influences on Dark Matter Halos and Consequences for the Galaxies Within Them (1997)

Lemson, Gerard, Kauffmann, Guinevere

We use large N-body simulations of dissipationless gravitational clustering in cold dark matter (CDM) cosmologies to study whether the properties of dark matter halos are affected by their...

Chemical Enrichment and the Origin of the Colour-Magnitude Relation of Elliptical Galaxies in a Hierarchical Merger Model (1997)

Kauffmann, Guinevere, Charlot, Stephane

In this paper, we present a model of the formation and chemical enrichment of elliptical galaxies that differs from the conventional picture in two ways: 1)Ellipticals do not form in a single...

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...

Disk galaxies at Z=0 and at High Redshift: an explanation of the observed evolution of damped Ly-alpha systems (1995)

Kauffmann, Guinevere

The analysis of disk formation is based on the White & Rees (1978) picture, in which disk galaxies form by continuous cooling and accretion of gas within a merging hierarchy of dark matter halos. A...

Galaxy Formation and Large-Scale Bias (1995)

Kauffmann, Guinevere, Nusser, Adi, Steinmetz, Matthias

We outline a simple approach to understanding the physical origin of bias in the distribution of galaxies relative to that of dark matter. The first step is to specify how collapsed, virialized halos...

The Ages of Elliptical Galaxies in a Merger Model (1995)

Kauffmann, Guinevere

The tightness of the observed colour-magnitude and Mg$_{2}$- velocity dispersion relations for elliptical galaxies has often been cited as an argument against a picture in which ellipticals form by...

The Observed Properties of High-Redshift Cluster Galaxies (1994)

Kauffmann, Guinevere

We use the semi-analytic models of galaxy formation developed by Kauffmann, White \& Guiderdoni to generate predictions for the observed properties of cluster and group galaxies at redshifts between...

Hierarchical Clustering and the Butcher-Oemler Effect (1994)

Kauffmann, Guinevere

We show that the rapid evolution in the fraction of blue, star-forming galaxies seen in clusters as a function of redshift (the Butcher-Oemler effect) can be explained very simply if structure...

Constraints on Models of Galaxy Formation from the Evolution of Damped Ly$\alpha$ Absorption Systems (1994)

Kauffmann, Guinevere, Charlot, Stéphane

There is accumulating observational evidence suggesting that damped Ly$\alpha$ absorption systems systems are the progenitors of present-day spiral galaxies. We use the observed properties of these...
