Journal Article
Cowley, W., Baugh, C., Cole, S., Frenk, C., & Lacey, C. (2018). Predictions for deep galaxy surveys with JWST from ΛCDM. Monthly Notices of the Royal Astronomical Society, 474(2), 2352-2372. https://doi.org/10.1093/mnras/stx2897

We present predictions for the outcome of deep galaxy surveys with the James Webb Space Telescope (JWST) obtained from a physical model of galaxy formation in Λ cold dark matter. We use the latest version of the GALFORM model, embedded within a new (... Read More about Predictions for deep galaxy surveys with JWST from ΛCDM.

The effect of thermal velocities on structure formation in N-body simulations of warm dark matter (2017)
Journal Article
Leo, M., Baugh, C., Li, B., & Pascoli, S. (2017). The effect of thermal velocities on structure formation in N-body simulations of warm dark matter. Journal of Cosmology and Astroparticle Physics, 2017(11), Article 017. https://doi.org/10.1088/1475-7516/2017/11/017

We investigate the impact of thermal velocities in N-body simulations of structure formation in warm dark matter models. Adopting the commonly used approach of adding thermal velocities, randomly selected from a Fermi-Dirac distribution, to the gravi...

The host dark matter haloes of [O II] emitters at 0.5 < z < 1.5 (2017)
Journal Article
Gonzalez-Perez, V., Comparat, J., Norberg, P., Baugh, C., Contreras, S., Lacey, C., …Humphries, J. (2018). The host dark matter haloes of [O II] emitters at 0.5 < z < 1.5. Monthly Notices of the Royal Astronomical Society, 474(3), 4024-4038. https://doi.org/10.1093/mnras/stx2807

Emission line galaxies (ELGs) are used in several ongoing and upcoming surveys (SDSSIV/eBOSS, DESI) as tracers of the dark matter distribution. Using a new galaxy formation model, we explore the characteristics of [O II] emitters, which dominate opti... Read More about The host dark matter haloes of [O II] emitters at 0.5 < z < 1.5.

A lightcone catalogue from the Millennium-XXL simulation (2017)
Journal Article
Smith, A., Cole, S., Baugh, C., Zheng, Z., Angulo, R., Norberg, P., & Zehavi, I. (2017). A lightcone catalogue from the Millennium-XXL simulation. Monthly Notices of the Royal Astronomical Society, 470(4), 4646-4661. https://doi.org/10.1093/mnras/stx1432

Future galaxy surveys require realistic mock catalogues to understand and quantify systematics in order to make precise cosmological measurements. We present a halo lightcone catalogue and halo occupation distribution (HOD) galaxy catalogue built usi... Read More about A lightcone catalogue from the Millennium-XXL simulation.

Understanding the non-linear clustering of high-redshift galaxies (2017)
Journal Article
Jose, C., Baugh, C., Lacey, C., & Subramanian, K. (2017). Understanding the non-linear clustering of high-redshift galaxies. Monthly Notices of the Royal Astronomical Society, 469(4), 4428-4436. https://doi.org/10.1093/mnras/stx1014

We incorporate the non-linear clustering of dark matter haloes, as modelled by Jose et al. into the halo model to better understand the clustering of Lyman break galaxies (LBGs) in the redshift range z = 3–5. We find that, with this change, the predi... Read More about Understanding the non-linear clustering of high-redshift galaxies.

Blending bias impacts the host halo masses derived from a cross-correlation analysis of bright submillimetre galaxies (2017)
Journal Article
Cowley, W., Lacey, C., Baugh, C., Cole, S., & Wilkinson, A. (2017). Blending bias impacts the host halo masses derived from a cross-correlation analysis of bright submillimetre galaxies. Monthly Notices of the Royal Astronomical Society, 469(3), 3396-3404. https://doi.org/10.1093/mnras/stx928

Placing bright submillimetre galaxies (SMGs) within the broader context of galaxy formation and evolution requires accurate measurements of their clustering, which can constrain the masses of their host dark matter haloes. Recent work has shown that... Read More about Blending bias impacts the host halo masses derived from a cross-correlation analysis of bright submillimetre galaxies.

Abell 2744: too much substructure for ΛCDM? (2017)
Journal Article
Schwinn, J., Jauzac, M., Baugh, C., Bartelmann, M., Eckert, D., Harvey, D., …Massey, R. (2017). Abell 2744: too much substructure for ΛCDM?. Monthly Notices of the Royal Astronomical Society, 467(3), 2913-2923. https://doi.org/10.1093/mnras/stx277

The massive substructures found in Abell 2744 by Jauzac et al. present a challenge to the cold dark matter paradigm due to their number and proximity to the cluster centre. We use one of the biggest N-body simulations, the Millennium XXL, to investig... Read More about Abell 2744: too much substructure for ΛCDM?.

The far infra-red SEDs of main sequence and starburst galaxies (2017)
Journal Article

We compare observed far infrared/sub-millimetre (FIR/sub-mm) galaxy spectral energy distributions (SEDs) of massive galaxies (M⋆ ≳ 1010 h−1 M⊙) derived through a stacking analysis with predictions from a new model of galaxy formation. The FIR SEDs of... Read More about The far infra-red SEDs of main sequence and starburst galaxies.
