Journal Article
van de Voort, F., Bahé, Y., Bower, R., Correa, C., Crain, R., Schaye, J., & Theuns, T. (2017). The environmental dependence of gas accretion onto galaxies: quenching satellites through starvation. Monthly Notices of the Royal Astronomical Society, 466(3), 3460-3471. https://doi.org/10.1093/mnras/stw3356

Galaxies that have fallen into massive haloes may no longer be able to accrete gas from their surroundings: a process referred to as ‘starvation’ or ‘strangulation’ of satellites. We study the environmental dependence of gas accretion on to galaxies... Read More about The environmental dependence of gas accretion onto galaxies: quenching satellites through starvation.

Journal Article
Norris, M., Van de Ven, G., Schinnerer, E., Crain, R., Meidt, S., Groves, B., …Theuns, T. (2016). Being WISE II: Reducing the Influence of Star formation History on the Mass-to-Light Ratio of Quiescent Galaxies. Astrophysical Journal, 832(2), Article 198. https://doi.org/10.3847/0004-637x/832/2/198

Stellar population synthesis models can now reproduce the photometry of old stellar systems (age > 2 Gyr) in the near-infrared (NIR) bands at 3.4 and 4.6μm (WISE W1 & W2 or IRAC 1 & 2). In this paper we derive stellar mass-to-light ratios for these a... Read More about Being WISE II: Reducing the Influence of Star formation History on the Mass-to-Light Ratio of Quiescent Galaxies.

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.

The origin of scatter in the stellar mass-halo mass relation of central galaxies in the EAGLE simulation (2016)
Journal Article
Matthee, J., Schaye, J., Crain, R., Schaller, M., Bower, R., & Theuns, T. (2017). The origin of scatter in the stellar mass-halo mass relation of central galaxies in the EAGLE simulation. Monthly Notices of the Royal Astronomical Society, 465(2), 2381-2396. https://doi.org/10.1093/mnras/stw2884

We use the hydrodynamical EAGLE simulation to study the magnitude and origin of the scatter in the stellar mass–halo mass relation for central galaxies. We separate cause and effect by correlating stellar masses in the baryonic simulation with halo p...

Angular momentum evolution of galaxies in EAGLE (2016)
Journal Article

We use the EAGLE cosmological hydrodynamic simulation suite to study the specific angular momentum of galaxies, j, with the aims of (i) investigating the physical causes behind the wide range of j at fixed mass and (ii) examining whether simple, theo...

Size evolution of normal and compact galaxies in the EAGLE simulation (2016)
Journal Article

We present the evolution of galaxy sizes, from redshift 2 to 0, for actively star forming and passive galaxies in the cosmological hydrodynamical 1003 cMpc3 simulation of the EAGLE project. We find that the sizes increase with stellar mass, but that... Read More about Size evolution of normal and compact galaxies in the EAGLE simulation.

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

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.

Observations of galaxies in the local Universe have shown that both the ionized gas and the stars of satellites are more metal-rich than of equally massive centrals. To gain insight into the connection between this metallicity enhancement and other d... Read More about The origin of the enhanced metallicity of satellite galaxies.
