Linear perturbations in Galileon gravity models (2012)
Journal Article
Barreira, A., Li, B., Baugh, C., & Pascoli, S. (2012). Linear perturbations in Galileon gravity models. Physical Review D, 86(12), Article 124016. https://doi.org/10.1103/physrevd.86.124016

We study the cosmology of Galileon modified gravity models in the linear perturbation regime. We derive the fully covariant and gauge invariant perturbed field equations using two different methods, which give consistent results, and solve them using...

The accuracy of the UV continuum as an indicator of the star formation rate in galaxies (2012)
Journal Article
Wilkins, S., Gonzalez-Perez, V., Lacey, C., & Baugh, C. (2012). The accuracy of the UV continuum as an indicator of the star formation rate in galaxies. Monthly Notices of the Royal Astronomical Society, 427(2), 1490-1496. https://doi.org/10.1111/j.1365-2966.2012.22092.x

The rest-frame intrinsic UV luminosity is often used as an indicator of the instantaneous star formation rate (SFR) in a galaxy. While it is in general a robust indicator of the ongoing star formation activity, the precise value of the calibration re...

Scaling relations for galaxy clusters in the Millennium-XXL simulation (2012)
Journal Article

We present a very large high-resolution cosmological N-body simulation, the Millennium-XXL or MXXL, which uses 303 billion particles to represent the formation of dark matter structures throughout a 4.1 Gpc box in a Λ cold dark matter cosmology. We c... Read More about Scaling relations for galaxy clusters in the Millennium-XXL simulation.

Predictions for the CO emission of galaxies from a coupled simulation of galaxy formation and photon-dominated regions (2012)
Journal Article

Predictions for the CO emission of galaxies from a coupled simulation of galaxy formation and photon-dominated regions.

We combine the galaxy formation model GALFORM with the photon-dominated region code UCL−PDR to study the emission from the rotational transitions of 12CO (CO) in galaxies from z = 0 to z = 6 in the Λcold dark matter framework. GALFORM is used to pred... Read More about Predictions for the CO emission of galaxies from a coupled simulation of galaxy formation and photon-dominated regions.

The clustering of Hα emitters at z = 2.23 from HiZELS (2012)
Journal Article

We present a clustering analysis of 370 high-confidence Hα emitters (HAEs) at z = 2.23. The HAEs are detected in the Hi-Z Emission Line Survey (HiZELS), a large-area blank field 2.121 μm narrow-band survey using the United Kingdom Infrared Telescope...

The contribution of star-forming galaxies to fluctuations in the cosmic background light (2012)
Journal Article
Kim, H., Lacey, C., Cole, S., Baugh, C., Frenk, C., & Efstathiou, G. (2012). The contribution of star-forming galaxies to fluctuations in the cosmic background light. Monthly Notices of the Royal Astronomical Society, 425(4), 2674-2687. https://doi.org/10.1111/j.1365-2966.2012.21641.x

Star-forming galaxies which are too faint to be detected individually produce intensity fluctuations in the cosmic background light. This contribution needs to be taken into account as a foreground when using the primordial signal to constrain cosmol...

The journey of QSO haloes from z ∼ 6 to the present (2012)

We apply a recently developed scaling technique to the Millennium-XXL, one of the largest cosmological N-body simulations carried out to date (3 × 1011 particles within a cube of volume ∼70 Gpc3). This allows us to investigate the cosmological parame... Read More about The journey of QSO haloes from z ∼ 6 to the present.

We use large-volume N-body simulations to predict the clustering of dark matter in redshift space in f(R) modified gravity cosmologies.
