Designing a space-based galaxy redshift survey to probe dark energy (2010)
Journal Article
Wang, Y., Percival, W., Cimatti, A., Mukherjee, P., Guzzo, L., Baugh, C., …Zamorani, G. (2010). Designing a space-based galaxy redshift survey to probe dark energy. Monthly Notices of the Royal Astronomical Society, 409(2), 737-749. https://doi.org/10.1111/j.1365-2966.2010.17335.x

A space-based galaxy redshift survey would have enormous power in constraining dark energy and testing general relativity, provided that its parameters are suitably optimized. We study viable space-based galaxy redshift surveys, exploring the depende... Read More about Designing a space-based galaxy redshift survey to probe dark energy.

The Parameter Space of Galaxy Formation (2010)
Journal Article
Bower, R., Vernon, I., Goldstein, M., Benson, A., Lacey, C., Baugh, C., …Frenk, C. (2010). The Parameter Space of Galaxy Formation. Monthly Notices of the Royal Astronomical Society, 407(4), 2017-2045. https://doi.org/10.1111/j.1365-2966.2010.16991.x

Semi-analytic models are a powerful tool for studying the formation of galaxies. However, these models inevitably involve a significant number of poorly constrained parameters that must be adjusted to provide an acceptable match to the observed Unive...

The redshift evolution of the mass function of cold gas in hierarchical galaxy formation models (2010)
Journal Article

Accurately predicting how the cosmic abundance of neutral hydrogen evolves with redshift is a challenging problem facing modellers of galaxy formation. We investigate the predictions of four currently favoured semi-analytical galaxy formation models...

How BAO measurements can fail to detect quintessence (2010)
Presentation / Conference Contribution
Jennings, E., Baugh, C., Angulo, R., & Pascoli, S. (2010). How BAO measurements can fail to detect quintessence. In J. Alimi, & A. Fuözfa (Eds.), AIP Conference Proceedings (945-954). https://doi.org/10.1063/1.3462739

We model the nonlinear growth of cosmic structure in different dark energy models, using large volume N‐body simulations. We consider a range of quintessence models which feature both rapidly and slowly varying dark energy equations of state, and com...

Future galaxy surveys will map the galaxy distribution in the redshift interval 0.5 < z < 2 using near-infrared cameras and spectrographs. The primary scientific goal of such surveys is to constrain the nature of the dark energy by measuring the larg...

We use a model for the evolution of galaxies in the far-infrared (far-IR) based on the Λ-cold dark matter cosmology to make detailed predictions for the upcoming cosmological surveys with the Herschel Space Observatory. We use the combined GALFORM se... Read More about Predictions for Herschel from Λ-cold dark matter : unveiling the cosmic star formation history.

Extremely Red Objects in a Hierarchical Universe (2010)

We analyse whether hierarchical formation models based on Λ Cold Dark Matter Cosmology can produce enough massive red galaxies to match observations. For this purpose, we compare observations with the predictions from two published models for the abu... Read More about Extremely Red Objects in a Hierarchical Universe.

Future galaxy redshift surveys aim to measure cosmological quantities from the galaxy power spectrum. A prime example is the detection of baryonic acoustic oscillations, providing a standard ruler to measure the dark energy equation of state, w(z), t...
