The many lives of active galactic nuclei: cooling flows, black holes and the luminosities and colour
We simulate the growth of galaxies and their central supermassive black holes by implementing a suite of semi-analytic models on the output of the Millennium Run, a very large simulation of theExpand

Simulations of Early Structure Formation: Primordial Gas Clouds
We use cosmological simulations to study the origin of primordial star-forming clouds in a ΛCDM universe, by following the formation of dark matter halos and the cooling of gas within them. To modelExpand

Formation of Primordial Stars in a ΛCDM Universe
We study the formation of the first generation of stars in the standard cold dark matter model. We use a very high resolution cosmological hydrodynamic simulation that achieves a dynamic range ofExpand

The Structure and Evolution of Early Cosmological H II Regions
We study the formation and evolution of H II regions around the first stars formed at redshifts z = 10-30. We use a one-dimensional Lagrangian hydrodynamics code that self-consistently incorporatesExpand

Formation of Primordial Supermassive Stars by Rapid Mass Accretion
Supermassive stars (SMSs) forming via very rapid mass accretion () could be precursors of supermassive black holes observed beyond a redshift of about six. Extending our previous work, here we studyExpand

Searching for massive clusters in weak lensing surveys
We explore the ability of weak lensing surveys to locate massive clusters. We use both analytic models of dark matter haloes and mock weak lensing surveys generated from a large cosmological N-bodyExpand

Non-Gaussian cosmic microwave background temperature fluctuations from peculiar velocities of clusters
We use numerical simulations of a (480 Mpc h−1)3 volume to show that the distribution of peak heights in maps of the temperature fluctuations from the kinematic and thermal Sunyaev–Zeldovich (SZ)Expand

Weakly Self-interacting Dark Matter and the Structure of Dark Halos
We study the formation of dark halos in a ΛCDM universe under the assumption that cold dark matter (CDM) particles have a finite cross section for elastic collisions. We compare evolution when CDMExpand

One Hundred First Stars : Protostellar Evolution and the Final Masses
We perform a large set of radiation hydrodynamic simulations of primordial star formation in a fully cosmological context. Our statistical sample of 100 First Stars shows that the first generation ofExpand

The onset of star formation 250 million years after the Big Bang
A fundamental quest of modern astronomy is to locate the earliest galaxies and study how they influenced the intergalactic medium a few hundred million years after the Big Bang1–3. The abundance ofExpand
