The properties of ‘dark’ ΛCDM haloes in the Local Group (2016)
Journal Article
Benítez-Llambay, A., Navarro, J., Frenk, C., Sawala, T., Oman, K., Fattahi, A., …Theuns, T. (2017). The properties of ‘dark’ ΛCDM haloes in the Local Group. Monthly Notices of the Royal Astronomical Society, 465(4), 3913-3926. https://doi.org/10.1093/mnras/stw2982

We examine the baryon content of low-mass Λ cold dark matter (ΛCDM) haloes (108 < M200/M⊙ < 5 × 109) using the APOSTLE cosmological hydrodynamical simulations. Most of these systems are free of stars and have a gaseous content set by the combined eff... Read More about The properties of ‘dark’ ΛCDM haloes in the Local Group.

We examine the spatial distribution of the oldest and most metal-poor stellar populations of Milky Way-sized galaxies using the A Project Of Simulating The Local Environment (APOSTLE) cosmological hydrodynamical simulations of the Local Group. In agr... Read More about The oldest and most metal-poor stars in the APOSTLE Local Group simulations.

Identifying true satellites of the Magellanic Clouds (2016)
Journal Article
Sales, L., Navarro, J., Kallivayalil, N., & Frenk, C. (2017). Identifying true satellites of the Magellanic Clouds. Monthly Notices of the Royal Astronomical Society, 465(2), 1879-188. https://doi.org/10.1093/mnras/stw2816

The hierarchical nature of ΛCDM suggests that the Magellanic Clouds must have been surrounded by a number of satellites before their infall into the Milky Way halo. Many of those satellites should still be in close proximity to the Clouds, but some c... Read More about Identifying true satellites of the Magellanic Clouds.

The metal enrichment of passive galaxies in cosmological simulations of galaxy formation (2016)
Journal Article
Okamoto, T., Nagashima, M., Lacey, C., & Frenk, C. (2017). The metal enrichment of passive galaxies in cosmological simulations of galaxy formation. Monthly Notices of the Royal Astronomical Society, 464(4), 4866-4874. https://doi.org/10.1093/mnras/stw2729

Massive early-type galaxies have higher metallicities and higher ratios of α elements to iron than their less massive counterparts. Reproducing these correlations has long been a problem for hierarchical galaxy formation theory, both in semi-analytic...

The dark nemesis of galaxy formation: why hot haloes trigger black hole growth and bring star formation to an end (2016)
Journal Article
Bower, R., Schaye, J., Frenk, C., Theuns, T., Schaller, M., Crain, R., & McAlpine, S. (2017). The dark nemesis of galaxy formation: why hot haloes trigger black hole growth and bring star formation to an end. Monthly Notices of the Royal Astronomical Society, 465(1), 32-44. https://doi.org/10.1093/mnras/stw2735

Galaxies fall into two clearly distinct types: ‘blue-sequence’ galaxies which are rapidly forming young stars, and ‘red-sequence’ galaxies in which star formation has almost completely ceased. Most galaxies more massive than 3 × 1010 M⊙ follow the re... Read More about The dark nemesis of galaxy formation: why hot haloes trigger black hole growth and bring star formation to an end.

Size matters: abundance matching, galaxy sizes, and the Tully-Fisher relation in EAGLE (2016)
Journal Article
Ferrero, I., Navarro, J., Abadi, M., Sales, L., Bower, R., Crain, R., …Theuns, T. (2017). Size matters: abundance matching, galaxy sizes, and the Tully-Fisher relation in EAGLE. Monthly Notices of the Royal Astronomical Society, 464(4), 4736-4746. https://doi.org/10.1093/mnras/stw2691

The Tully–Fisher relation (TFR) links the stellar mass of a disc galaxy, Mstr, to its rotation speed: it is well approximated by a power law, shows little scatter, and evolves weakly with redshift. The relation has been interpreted as reflecting the... Read More about Size matters: abundance matching, galaxy sizes, and the Tully-Fisher relation in EAGLE.

Substructure and galaxy formation in the Copernicus Complexio warm dark matter simulations (2016)
Journal Article

We use the Copernicus Complexio (coco) high-resolution N-body simulations to investigate differences in the properties of small-scale structures in the standard cold dark matter (CDM) model and in a model with a cutoff in the initial power spectrum o...

The low-mass end of the baryonic Tully–Fisher relation (2016)
Journal Article

The scaling of disc galaxy rotation velocity with baryonic mass (the ‘baryonic Tully–Fisher’ relation, BTF) has long confounded galaxy formation models. It is steeper than the M ∝ V3 scaling relating halo virial masses and circular velocities and its... Read More about The low-mass end of the baryonic Tully–Fisher relation.

A chronicle of galaxy mass assembly in the EAGLE simulation (2016)
Journal Article

We analyse the mass assembly of central galaxies in the Evolution and Assembly of Galaxies and their Environments (EAGLE) hydrodynamical simulations. We build merger trees to connect galaxies to their progenitors at different redshifts and characteri... Read More about A chronicle of galaxy mass assembly in the EAGLE simulation.

Reionisation in sterile neutrino cosmologies (2016)
Journal Article

We investigate the process of reionisation in a model in which the dark matter is a warm elementary particle such as a sterile neutrino. We focus on models that are consistent with the dark matter decay interpretation of the recently detected line at... Read More about Reionisation in sterile neutrino cosmologies.
