Journal Article
O'Kane, C. J., Kuchner, U., Gray, M. E., & Aragón-Salamanca, A. (2024). The effect of cosmic web filaments on galaxy evolution. Monthly Notices of the Royal Astronomical Society, 534(3), 1682-1699. https://doi.org/10.1093/mnras/stae2142

Galaxy properties are known to be affected by their environment. This is well established for the extremes of the density scales, between the high-density cluster environment and the low-density field. It is however not fully understood how the inter...

Reconsidering the dynamical states of galaxy clusters using PCA and UMAP (2024)
Journal Article
Haggar, R., De Luca, F., De Petris, M., Sazonova, E., Taylor, J. E., Knebe, A., …Power, C. (2024). Reconsidering the dynamical states of galaxy clusters using PCA and UMAP. Monthly Notices of the Royal Astronomical Society, 532(1), 1031–1048. https://doi.org/10.1093/mnras/stae1566

Numerous metrics exist to quantify the dynamical state of galaxy clusters, both observationally and within simulations. Many of these correlate strongly with one another, but it is not clear whether all of these measures probe the same intrinsic prop...

Using cosmological simulations of galaxy cluster regions from THE THREE HUNDRED project, we study the nature of gas in filaments feeding massive clusters. By stacking the diffuse material of filaments throughout the cluster sample, we measure average...

Galaxy clusters grow by accreting galaxies as individual objects, or as members of a galaxy group. These groups can strongly impact galaxy evolution, stripping the gas from galaxies, and enhancing the rate of galaxy mergers. However, it is not clear...
