How do galaxies populate Dark Matter halos? (2009)

Guo, Qi, White, Simon, Li, Cheng, Boylan-Kolchin, Michael

For any assumed stellar Initial Mass Function, the Sloan Digital Sky Survey (SDSS) gives a precise determination of the stellar mass function of galaxies for 10^8 M_sun < M_* < 10^12 M_sun. Within...

On merger bias and the clustering of quasars (2009)

Bonoli, Silvia, Shankar, Francesco, White, Simon, Springel, Volker, Wyithe, Stuart

We use the large catalogues of haloes available for the Millennium Simulation to test whether recently merged haloes exhibit stronger large-scale clustering than other haloes of the same mass. This...

Bell, Eric, Davis, Marc, Dey, Arjun, Van Dokkum, Pieter, Ellis, Richard, Eisenstein, Daniel, ...

Over the last decade optical spectroscopic surveys have characterized the low redshift galaxy population and uncovered populations of star-forming galaxies back to z ~ 7. This work has shown that the...

The Environments of Starburst and Post-Starburst Galaxies at z = 0.4-0.8 (2009)

Post-starburst (E+A or k+a) spectra, characterized by their exceptionally strong Balmer lines in absorption and the lack of emission lines, belong to galaxies in which the star formation activity...

The relation between star formation, morphology, and local density in high-redshift clusters and groups (2008)

Poggianti, Bianca M., Desai, Vandana, Finn, Rose, Bamford, Steven, De Lucia, Gabriella, Varela, Jesus, ...

We investigate how the [O II] properties and the morphologies of galaxies in clusters and groups at z = 0.4–0.8 depend on projected local galaxy density, and compare with the field at similar...

Disk Sizes in a LCDM Universe (2008)

Guo, Qi, White, Simon

We introduce a model which uses semi-analytic techniques to trace formation and evolution of galaxy disks in their cosmological context. For the first time we model the growth of gas and stellar...

Poggianti, Bianca M., Desai, Vandana, Finn, Rose, Bamford, Steven, De Lucia, Gabriella, Varela, Jesus, ...

We investigate how the [OII] properties and the morphologies of galaxies in clusters and groups at z=0.4-0.8 depend on projected local galaxy density, and compare with the field at similar redshifts...

Identification of absorbing galaxies towards the QSO J2233--606 in the Hubble Deep Field South (2007)

Laurence Tresse Michel, Michel Dennefeld, Patrick Petitjean, Stefano Cristiani, Simon White

. We present spectroscopic observations of galaxies lying within 1 0 of QSO J2233--606 in the Hubble Deep Field South (HDF-S). Several are found to be coincident in redshift with absorption-line...

Simulating Weak Lensing By Large-Scale Structure (2007)

This paper introduces a stand-alone case/knowledge acquisition tool, called COCKATOO (Constraint-Capable Knowledge Acquisition Tool), which uses an Extended BNF grammar to represent the main...

Ratio of nose blow results to intakes during the decommissioning of a facility at Dounreay (2007)

Spencer, David, Bull, Richard K., White, Simon

During the decommissioning of a large glove box facility at Dounreay, in addition to engineering and administration controls, workers wore pressurised suits to minimise their intake of radionuclides....

A Constraint-Based Approach to the Description & Detection of Fitness-for-Purpose. (2002)

Sleeman, Derek, White, Simon

This paper introduces the notion of fitness-for-purpose, presents a tractable, approximate approach to the recognition of fitness-for-purpose, and describes a working implementation using constraint...

A Grammar-driven Knowledge Acquisition Tool that incorporates Constraint Propagation”, to appear (2001)

Simon White

To acquire knowledge that is fit for a specific purpose, it is very desirable to have a structured, declarative expression of the knowledge that is needed. This paper introduces a stand-alone...

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...
