The diffuse stellar component of galaxy clusters made up of intergalactic stars is termed the intracluster light (ICL). Though there is a developing understanding of the mechanisms by which the ICL is formed, no strong consensus has yet been reached...

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...

Upcoming wide-field spectroscopic surveys will observe galaxies in a range of cosmic web environments in and around galaxy clusters. In this paper, we test and quantify how successfully we will be able to identify the environment of individual galaxi...

Using the data set of The Three Hundred project, i.e. 324 hydrodynamical resimulations of cluster-sized haloes and the regions of radius 15 around them, we study galaxy pairs in high-density environments. By projecting the galaxies' 3D coordinates on... Read More about Galaxy pairs in THE THREE HUNDRED simulations II: studying bound ones and identifying them via machine learning.

The Three Hundred project: Galaxy groups do not survive cluster infall (2022)
Journal Article

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...

Close pairs of galaxies have been broadly studied in the literature as a way to understand galaxy interactions and mergers. In observations, they are usually defined by setting a maximum separation in the sky and in velocity along the line of sight,...
