Journal Article
Mostoghiu, R., Knebe, A., Cui, W., Pearce, F. R., Yepes, G., Power, C., Dave, R., & Arth, A. (2018). The Three Hundred Project: the evolution of galaxy cluster density profiles. Monthly Notices of the Royal Astronomical Society, 483(3), 3390-3403. https://doi.org/10.1093/mnras/sty3306

Recent numerical studies of the dark matter density profiles of massive galaxy clusters (Mhalo > 1015 M) show that their median radial mass density profile remains unchanged up to z > 1, displaying a highly self-similar evolution. We verify this by u... Read More about The Three Hundred Project: the evolution of galaxy cluster density profiles.

The Three Hundred Project: the influence of environment on simulated galaxy properties (2018)
Journal Article
Wang, Y., Pearce, F., Knebe, A., Yepes, G., Cui, W., Power, C., Arth, A., Gottlöber, S., Petris, M. D., Brown, S., & Feng, L. (2018). The Three Hundred Project: the influence of environment on simulated galaxy properties. Astrophysical Journal, 868(2), Article 130. https://doi.org/10.3847/1538-4357/aae52e

The relationship between galaxy properties and environment is a widely discussed topic within astrophysics. Here, we use galaxy samples from hydrodynamical resimulations to examine this relationship. We use the overdensity (δ1)within a h-1Mpc sphere... Read More about The Three Hundred Project: the influence of environment on simulated galaxy properties.

Journal Article

Monthly Notices of the Royal Astronomical Society, 481(1), 324-340. https://doi.org/10.1093/mnras/sty2257

The primary difficulty in measuring dynamical masses of galaxy clusters from galaxy data lies in the separation between true cluster members from interloping galaxies along the line of sight. We study the impact of membership contamination and incomp... Read More about Galaxy Cluster Mass Reconstruction Project – IV.

Monthly Notices of the Royal Astronomical Society, 480(3), 2898-2915. https://doi.org/10.1093/mnras/sty2111

We introduce the The Three Hundred project, an endeavour to model 324 large galaxy clusters with full-physics hydrodynamical re-simulations. Here we present the dataset and study the differences to observations for fundamental galaxy cluster properti...

Journal Article
Asquith, R., Pearce, F. R., Almaini, O., Knebe, A., Gonzalez-Perez, V., Benson, A., Blaizot, J., Carretero, J., Castander, F. J., Cattaneo, A., Cora, S. A., Croton, D. J., Devriendt, J.

Monthly Notices of the Royal Astronomical Society, 480(1), 1197–1210. https://doi.org/10.1093/mnras/sty1870

We present a comparison of the observed evolving galaxy stellar mass functions with the predictions of eight semi-analytic models and one halo occupation distribution model. While most models are able to fit the data at low redshift, some of them str...

An SPH multi-fluid model based on quasi-buoyancy for interface stabilization up to high density ratios and realistic wave speed ratios (2018)
Journal Article
Kruisbrink, A. C., Pearce, F., Yue, T., & Morvan, H. (2018). An SPH multi-fluid model based on quasi-buoyancy for interface stabilization up to high density ratios and realistic wave speed ratios. International Journal for Numerical Methods in Fluids, 87(10), https://doi.org/10.1002/fld.4498

We introduce a Smoothed Particle Hydrodynamics (SPH) concept for the stabilization of the interface between two fluids. It is demonstrated that the change in the pressure gradient across the interface leads to a force imbalance. This force imbalance...
