Monthly Notices of the Royal Astronomical Society, 468(3), 2836-2849. https://doi.org/10.1093/mnras/stx621

N-body dark matter simulations of structure formation in the Λ cold dark matter (ΛCDM) model predict a population of subhaloes within Galactic haloes that have higher central densities than inferred for the Milky Way satellites, a tension known as th...

Projection effects in the strong lensing study of subhaloes (2017)
Journal Article
Li, R., Frenk, C., Cole, S., Wang, Q., & Gao, L. (2017). Projection effects in the strong lensing study of subhaloes. Monthly Notices of the Royal Astronomical Society, 468(2), 1426-1432. https://doi.org/10.1093/mnras/stx554

The defining characteristic of the cold dark matter (CDM) hypothesis is the presence of a very large number of low-mass haloes, too small to have made a visible galaxy. Other hypotheses for the nature of the dark matter, such as warm dark matter (WDM... Read More about Projection effects in the strong lensing study of subhaloes.

Gravitational redshift and asymmetric redshift-space distortions for stacked clusters (2017)
Journal Article
Cai, Y., Kaiser, N., Cole, S., & Frenk, C. (2017). Gravitational redshift and asymmetric redshift-space distortions for stacked clusters. Monthly Notices of the Royal Astronomical Society, 468(2), 1981-1993. https://doi.org/10.1093/mnras/stx469

We derive the expression for the observed redshift in the weak field limit in the observer's past light cone, including all relativistic terms up to second order in velocity. We then apply it to compute the cluster–galaxy cross-correlation functions... Read More about Gravitational redshift and asymmetric redshift-space distortions for stacked clusters.

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.

Achieving convergence in galaxy formation models by augmenting N-body merger trees (2016)
Journal Article
Benson, A., Cannella, C., & Cole, S. (2016). Achieving convergence in galaxy formation models by augmenting N-body merger trees. Computational Astrophysics and Cosmology, 3, Article 3. https://doi.org/10.1186/s40668-016-0016-3

Accurate modeling of galaxy formation in a hierarchical, cold dark matter universe requires the use of sufficiently high-resolution merger trees to obtain convergence in the predicted properties of galaxies. When semi-analytic galaxy formation models... Read More about Achieving convergence in galaxy formation models by augmenting N-body merger trees.

Galaxies in the EAGLE hydrodynamical simulation and in the Durham and Munich semi-analytical models (2016)
Journal Article

Monthly Notices of the Royal Astronomical Society, 461(4), 3457-3482. https://doi.org/10.1093/mnras/stw1525

We compare global predictions from the EAGLE hydrodynamical simulation, and two semi-analytic (SA) models of galaxy formation, L-GALAXIES and GALFORM. All three models include the key physical processes for the formation and evolution of galaxies and...

Satellite galaxies in semi-analytic models of galaxy formation with sterile neutrino dark matter (2016)
Journal Article
Lovell, M., Bose, S., Boyarsky, A., Cole, S., Frenk, C., Gonzalez-Perez, V., …Smith, A. (2016). Satellite galaxies in semi-analytic models of galaxy formation with sterile neutrino dark matter. Monthly Notices of the Royal Astronomical Society, 461(1), 60-72. https://doi.org/10.1093/mnras/stw1317

The sterile neutrino is a viable dark matter candidate that can be produced in the early Universe via non-equilibrium processes, and would therefore possess a highly non-thermal spectrum of primordial velocities. In this paper we analyse the process... Read More about Satellite galaxies in semi-analytic models of galaxy formation with sterile neutrino dark matter.

The clustering evolution of dusty star-forming galaxies (2016)
Journal Article

We present predictions for the clustering of galaxies selected by their emission at far-infrared (FIR) and sub-millimetre wavelengths. This includes the first predictions for the effect of clustering biases induced by the coarse angular resolution of... Read More about The clustering evolution of dusty star-forming galaxies.

The mass–concentration–redshift relation of cold and warm dark matter haloes (2016)

We use a suite of cosmological simulations to study the mass–concentration–redshift relation, c(M, z), of dark matter haloes. Our simulations include standard Λ-cold dark matter (CDM) models, and additional runs with truncated power spectra, consiste...

Constraints on the identity of the dark matter from strong gravitational lenses (2016)
Journal Article
Li, R., Frenk, C., Cole, S., Gao, L., Bose, S., & Hellwing, W. (2016). Constraints on the identity of the dark matter from strong gravitational lenses. Monthly Notices of the Royal Astronomical Society, 460(1), 363-372. https://doi.org/10.1093/mnras/stw939

The cold dark matter (CDM) cosmological model unambiguously predicts that a large number of haloes should survive as subhaloes when they are accreted into a larger halo. The CDM model would be ruled out if such substructures were shown not to exist.... Read More about Constraints on the identity of the dark matter from strong gravitational lenses.
