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
Kuchner, U., Aragón-Salamanca, A., Rost, A., Pearce, F. R., Gray, M. E., Cui, W., …Yepes, G. (2021). Cosmic filaments in galaxy cluster outskirts: quantifying finding filaments in redshift space.

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
Haggar, R., Pearce, F. R., Gray, M. E., Knebe, A., & Yepes, G. (2021). The Three Hundred Project: Substructure in hydrodynamical and dark matter simulations of galaxy groups around clusters. Monthly Notices of the Royal Astronomical Society, 502(1), 1191-1204. https://doi.org/10.1093/mnras/stab064

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.

The Three Hundred project: The gas disruption of infalling objects in cluster environments (2021)
Journal Article
Mostoghiu, R., Arthur, J., Pearce, F. R., Gray, M., Knebe, A., Cui, W., …Yepes, G. (2021). The Three Hundred project: The gas disruption of infalling objects in cluster environments. Monthly Notices of the Royal Astronomical Society, 501(4), 5029-5041. https://doi.org/10.1093/mnras/stab014

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.
