Using the data set of the three hundred project, i.e. a suite of 324 hydrodynamical resimulations of cluster-sized haloes, we study galaxy cluster mergers and their effect on colour and luminosity changes of their brightest cluster galaxies (BCG).

An inventory of galaxies in cosmic filaments feeding galaxy clusters: galaxy groups, backsplash galaxies, and pristine galaxies. Monthly Notices of the Royal Astronomical Society, 510(1), 581-592. https://doi.org/10.1093/mnras/stab3419

Galaxy clusters grow by accreting galaxies from the field and along filaments of the cosmic web. As galaxies are accreted they are affected by their local environment before they enter (pre-processing), and traverse the cluster potential. Observation...

Cosmic filaments in galaxy cluster outskirts: quantifying finding filaments in redshift space (2021)
Journal Article

Monthly Notices of the Royal Astronomical Society, 503(2), 2065-2076. https://doi.org/10.1093/mnras/stab567

Inferring line-of-sight distances from redshifts in and around galaxy clusters is complicated by peculiar velocities, a phenomenon known as the "Fingers of God" (FoG). This presents a significant challenge for finding filaments in large observational... Read More about Cosmic filaments in galaxy cluster outskirts: quantifying finding filaments in redshift space.

The Three Hundred Project: Substructure in hydrodynamical and dark matter simulations of galaxy groups around clusters (2021)
Journal Article

Dark matter-only simulations are able to produce the cosmic structure of a Lambda cold dark matter universe, at a much lower computational cost than more physically motivated hydrodynamical simulations. However, it is not clear how well smaller subst... Read More about The Three Hundred Project: Substructure in hydrodynamical and dark matter simulations of galaxy groups around clusters.

We analyse the gas content evolution of infalling haloes in cluster environments from The Three Hundred project, a collection of 324 numerically modelled galaxy clusters. The haloes in our sample were selected within 5R200 of the main cluster halo at... Read More about The Three Hundred project: The gas disruption of infalling objects in cluster environments.

The threehundred: the structure and properties of cosmic filaments in the outskirts of galaxy clusters (2020)

Monthly Notices of the Royal Astronomical Society, 502(1), 714-727. https://doi.org/10.1093/mnras/staa3792

Galaxy cluster outskirts are described by complex velocity fields induced by diffuse material collapsing towards filaments, gas, and galaxies falling into clusters, and gas shock processes triggered by substructures. A simple scenario that describes... Read More about The threehundred: the structure and properties of cosmic filaments in the outskirts of galaxy clusters.

Using 324 numerically modelled galaxy clusters, we investigate the radial and galaxy–halo alignment of dark matter subhaloes and satellite galaxies orbiting within and around them.
