On the use of particle based methods for cosmological hydrodynamical simulations (2013)
Presentation / Conference Contribution
Schaller, M., Bower, R., & Theuns, T. (2013, December). On the use of particle based methods for cosmological hydrodynamical simulations. Presented at 8th International SPHERIC Workshop, Trondheim, Norway

In this paper, we attempt to clarify the relation between different particle based methods and try to assess their viability in the context of osmological simulations. We identify two classes of methods depending on the number of neighbours required... Read More about On the use of particle based methods for cosmological hydrodynamical simulations.

We present the spatially resolved Hα dynamics of 16 star-forming galaxies at z ~ 0.81 using the new KMOS multi-object integral field spectrograph on the ESO Very Large Telescope. These galaxies, selected using 1.18 μm narrowband imaging from the 10 d... Read More about The dynamics of z = 0.8 Hα-selected star-forming galaxies from KMOS/CF-HiZELS.

We obtained Subaru FMOS observations of Hα emitting galaxies selected from the HiZELS, to investigate the relationship between stellar mass, metallicity and star formation rate (SFR) at z = 0.84–1.47, for comparison with the fundamental metallicity r...

Do group dynamics play a role in the evolution of member galaxies? (2013)
Journal Article

We examine galaxy groups from the present epoch to z ∼ 1 to explore the impact of group dynamics on galaxy evolution. We use group catalogues from the Sloan Digital Sky Survey (SDSS), the Group Environment and Evolution Collaboration (GEEC) and the h...

Efficient satellite quenching at z∼1 from the GEEC2 spectroscopic survey of galaxy groups (2013)
Journal Article

We present deep Gemini Multi-Object Spectrograph-South spectroscopy for 11 galaxy groups at 0.8 < z < 1.0, for galaxies with rAB < 24.75. Our sample is highly complete (>66 per cent) for eight of the 11 groups. Using an optical–near-infrared colour–c...

The merger rates and sizes of galaxies across the peak epoch of star formation from the HiZELS survey (2013)

We use the HiZELS narrow-band Hα survey in combination with CANDELS, UKIDSS and WIRDS near-infrared imaging, to investigate the morphologies, merger rates and sizes of a sample of Hα emitting galaxies in the redshift range z = 0.40-2.23, an epoch enc...

How supernova explosions power galactic winds (2013)
Journal Article

Feedback from supernovae is an essential aspect of galaxy formation. In order to improve subgrid models of feedback, we perform a series of numerical experiments to investigate how supernova explosions shape the interstellar medium (ISM) in a disc ga...

Construction and application to the BzK colour selection. Monthly Notices of the Royal Astronomical Society, 429(1), 556-578. https://doi.org/10.1093/mnras/sts355

We introduce a method for constructing end-to-end mock galaxy catalogues using a semi-analytical model of galaxy formation, applied to the halo merger trees extracted from a cosmological N-body simulation. The mocks that we construct are lightcone ca... Read More about Lightcone mock catalogues from semi-analytic models of galaxy formation - I. Construction and application to the BzK colour selection.
