Reconsidering the dynamical states of galaxy clusters using PCA and UMAP (2024)
Journal Article

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...

The three hundred project: thermodynamical properties, shocks, and gas dynamics in simulated galaxy cluster filaments and their surroundings (2023)
Journal Article

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...

The probability of identifying the cosmic web environment of galaxies around clusters motivated by the Weave Wide Field Cluster Survey (2023)
Journal Article

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...

Galaxy pairs in THE THREE HUNDRED simulations II: studying bound ones and identifying them via machine learning (2023)
Journal Article

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: Connection between star formation quenching and dynamical evolution in and around simulated galaxy clusters (2022)
Journal Article

In this work, we combine the semi-analytic model of galaxy formation and evolution SAG with the 102 relaxed simulated galaxy clusters from THE THREE HUNDRED project, and we study the link between the quenching of star formation (SF) and the physical...

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...

Forecasting the success of the WEAVE Wide-Field Cluster Survey on the extraction of the cosmic web filaments around galaxy clusters (2022)
Journal Article

Next-generation wide-field spectroscopic surveys will observe the infall regions around large numbers of galaxy clusters with high sampling rates for the first time. Here we assess the feasibility of extracting the large-scale cosmic web around clust...

Galaxy pairs in THE THREE HUNDRED simulations: a study on the performance of observational pair-finding techniques (2022)
Journal Article

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,...

A stochastic model to reproduce the star formation history of individual galaxies in hydrodynamic simulations (2022)
Journal Article

The star formation history (SFH) of galaxies is critical for understanding galaxy evolution. Hydrodynamical simulations enable us to precisely reconstruct the SFH of galaxies and establish a link to the underlying physical processes. In this work, we...

The Three Hundred project: The gizmo-simba run (2022)
Journal Article

We introduce gizmo-simba, a new suite of galaxy cluster simulations within The Three Hundred project. The Three Hundred consists of zoom re-simulations of 324 clusters with M 200≳ 1014.8, M ⊙ drawn from the MultiDark-Planck N-body simulation, run usi...
