Journal Article

In the outer regions of a galaxy cluster, galaxies may be either falling into the cluster for the first time, or have already passed through the cluster centre at some point in their past. To investigate these two distinct populations, we utilise The... Read More about The Three Hundred Project: Backsplash galaxies in simulations of clusters.

Monthly Notices of the Royal Astronomical Society, 491(1), 3923-3936. https://doi.org/10.1093/mnras/stz3176

Galaxy cluster outskirts mark the transition region from the mildly non-linear cosmic web to the highly non-linear, virialized, cluster interior. It is in this transition region that the intracluster medium (ICM) begins to influence the properties of...

The Three Hundred Project: the evolution of galaxy cluster density profiles (2018)
Journal Article

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.

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...

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...

With the advent of wide-field cosmological surveys, we are approaching samples of hundreds of thousands of galaxy clusters. While such large numbers will help reduce statistical uncertainties, the control of systematics in cluster masses is crucial.... Read More about Galaxy Cluster Mass Reconstruction Project: III.
