Journal Article
Cowley, W. I., Lacey, C. G., Baugh, C. M., & Cole, S. (2015). Simulated observations of sub-millimetre galaxies: the impact of single-dish resolution and field variance. Monthly Notices of the Royal Astronomical Society, 446(2), 1784-1798. https://doi.org/10.1093/mnras/stu2179

Recent observational evidence suggests that the coarse angular resolution [∼20 arcsec full width at half maximum (FWHM)] of single-dish telescopes at sub-mm wavelengths has biased the observed galaxy number counts by blending together the sub-mm emis...

Journal Article

Galaxy And Mass Assembly (GAMA): the dependence of the galaxy luminosity function on environment, redshift and colour. Monthly Notices of the Royal Astronomical Society, 445(2), 2125-2145. https://doi.org/10.1093/mnras/stu1886

We use 80 922 galaxies in the Galaxy And Mass Assembly (GAMA) survey to measure the galaxy luminosity function (LF) in different environments over the redshift range 0.04 < z < 0.26. The depth and size of GAMA allows us to define samples split by col...

The evolution of the star-forming sequence in hierarchical galaxy formation models (2014)
Journal Article
Mitchell, P., Lacey, C., Cole, S., & Baugh, C. (2014). The evolution of the star-forming sequence in hierarchical galaxy formation models. Monthly Notices of the Royal Astronomical Society, 444(3), 2637-2664. https://doi.org/10.1093/mnras/stu1639

It has been argued that the specific star formation rates of star-forming galaxies inferred from observational data decline more rapidly below z = 2 than is predicted by hierarchical galaxy formation models. We present a detailed analysis of this pro... Read More about The evolution of the star-forming sequence in hierarchical galaxy formation models.

The origin of the atomic and molecular gas contents of early-type galaxies – I. A new test of galaxy formation physics (2014)
Journal Article

A new test of galaxy formation physics. Monthly Notices of the Royal Astronomical Society, 443(2), 1002-1021. https://doi.org/10.1093/mnras/stu1209

We study the atomic (H I) and molecular hydrogen (H2) contents of early-type galaxies (ETGs) and their gas sources using the GALFORM model of galaxy formation. This model uses a self-consistent calculation of the star formation rate, which depends on... Read More about The origin of the atomic and molecular gas contents of early-type galaxies – I.

We use the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) Phase I data to study the conditional luminosity function of far-IR (250 μm) selected galaxies in optically selected galaxy groups from the Galaxy And Mass Assembly (GAMA) spectr...

Extending the halo mass resolution of N-body simulations (2014)
Journal Article

We present a scheme to extend the halo mass resolution of dark matter N-body simulations. The method uses the simulated density field to predict the number of sub-resolution haloes expected in different regions, taking as input the abundance and the...

Which galaxies dominate the neutral gas content of the Universe? (2014)
Journal Article

We study the contribution of galaxies with different properties to the global densities of star formation rate (SFR), atomic (H I) and molecular hydrogen (H2) as a function of redshift. We use the GALFORM model of galaxy formation, which is set in th... Read More about Which galaxies dominate the neutral gas content of the Universe?.

The cross-power spectrum between 21 cm emission and galaxies in hierarchical galaxy formation models (2014)
Journal Article

The correlation between 21 cm fluctuations and galaxies is sensitive to the astrophysical properties of the galaxies that drove reionization. Thus, detailed measurements of the cross-power spectrum and its evolution could provide a powerful measureme...
