Imprints of Mass Accretion History on Galaxy Cluster Morphology
Kabelo Tsiane, Camille Avestruz, Elena Rasia +6
Variations in dynamical states of galaxy clusters can introduce biases and scatter in observable-mass relations. The dynamical state of a cluster is an emergent feature of its mass…
Identifying backsplash galaxies using machine learning
Roan Haggar, Elizaveta Sazonova, Cameron R. Morgan +5
The galaxy population in the outskirts of a cluster contains members that have been pre-processed in groups and filaments, as well as backsplash galaxies -- those that have recentl…
Tracing the dynamical states and mass accretion histories of galaxy clusters in IllustrisTNG
Rashaad Reid, Syeda Lammim Ahad, Roan Haggar +2
As the largest and most recently formed stage of hierarchical structure, present-day galaxy clusters are predicted to have a broad range of late-time assembly histories. This diver…
Identifying group galaxies merging with massive clusters using machine learning
Rhys Jordan, Meghan E. Gray, Alfonso Aragón-Salamanca +3
The environment plays a critical role in galaxy evolution, with galaxy clusters and their infall regions offering diverse conditions that shape galaxies before they enter the dense…
The origin of the intra-cluster light in The Three Hundred simulations
A. Contreras-Santos, A. Knebe, W. Cui +9
We investigate the origin and formation mechanisms of the intra-cluster light (ICL) in The Three Hundred simulations, a set of 324 hydrodynamically resimulated massive galaxy clust…
The life and times of dark matter haloes: what will I be when I grow up?
Julian Onions, Frazer Pearce, Alexander Knebe +6
Are the most massive objects in the Universe today the direct descendants of the most massive objects at higher redshift? We address this question by tracing the evolutionary histo…
Cosmology from UNIONS weak lensing profiles of galaxy clusters
Charlie T. Mpetha, James E. Taylor, Yuba Amoura +12
Cosmological information is encoded in the structure of galaxy clusters. In Universes with less matter and larger initial density perturbations, clusters form earlier and have more…
The infall region as a complementary probe to cluster abundance
Charlie T. Mpetha, James E. Taylor, Yuba Amoura +1
Galaxy cluster abundance measurements provide a classic test of cosmology. They are most sensitive to the evolved amplitude of fluctuations, usually expressed as $S_8 = σ_8\sqrt{Ω_…
Constraining cosmological parameters using the splashback radius of galaxy clusters
Roan Haggar, Yuba Amoura, Charlie T. Mpetha +3
Cosmological parameters such as and can be measured indirectly using various methods, including galaxy cluster abundance and cosmic shear. These measurements c…
Reconsidering the dynamical states of galaxy clusters using PCA and UMAP
Roan Haggar, Federico De Luca, Marco De Petris +10
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…
Characterising the intra-cluster light in The Three Hundred simulations
Ana Contreras-Santos, Alexander Knebe, Weiguang Cui +7
We characterise the intra-cluster light (ICL) in ensembles of full-physics cluster simulations from The Three Hundred project, a suite of 324 hydrodynamical resimulations of cluste…
Galaxy pairs in The Three Hundred simulations II: studying bound ones and identifying them via machine learning
Ana Contreras-Santos, Alexander Knebe, Weiguang Cui +5
Using the data set of The Three Hundred project, i.e. 324 hydrodynamical resimulations of cluster-sized haloes and the regions of radius 15 Mpc around them, we study galaxy…
The Three Hundred project: connection between star formation quenching and dynamical evolution in and around simulated galaxy clusters
Tomás Hough, Sofía A. Cora, Roan Haggar +6
In this work, we combine the semi-analytic model of galaxy formation and evolution SAG with the relaxed simulated galaxy clusters from The Three Hundred project, and we study…
The Three Hundred project: Galaxy groups do not survive cluster infall
Roan Haggar, Ulrike Kuchner, Meghan E. Gray +4
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 galaxie…
Galaxy pairs in The Three Hundred simulations: a study on the performance of observational pair-finding techniques
Ana Contreras-Santos, Alexander Knebe, Weiguang Cui +5
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 ma…
SDSS-IV MaNGA: the chemical co-evolution of gas and stars in spiral galaxies
Michael J. Greener, Alfonso Aragón-Salamanca, Michael Merrifield +7
We investigate archaeologically how the metallicity in both stellar and gaseous components of spiral galaxies of differing masses evolve with time, using data from the SDSS-IV MaNG…
\textsc{The Three Hundred} project: The \textsc{Gizmo-Simba} run
Weiguang Cui, Romeel Dave, Alexander Knebe +22
We introduce \textsc{Gizmo-Simba}, a new suite of galaxy cluster simulations within \textsc{The Three Hundred} project. \textsc{The Three Hundred} consists of zoom re-simulations o…
The Three Hundred project: galaxy cluster mergers and their impact on the stellar component of brightest cluster galaxies
Ana Contreras-Santos, Alexander Knebe, Frazer Pearce +10
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 colou…
An inventory of galaxies in cosmic filaments feeding galaxy clusters: galaxy groups, backsplash galaxies, and pristine galaxies
Ulrike Kuchner, Roan Haggar, Alfonso Aragón-Salamanca +6
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 e…
The Three Hundred Project: Substructure in hydrodynamical and dark matter simulations of galaxy groups around clusters
Roan Haggar, Frazer R. Pearce, Meghan E. Gray +2
Dark matter-only simulations are able to produce the cosmic structure of a CDM universe, at a much lower computational cost than more physically motivated hydrodynamical simulat…
The Three Hundred project: shapes and radial alignment of satellite, infalling, and backsplash galaxies
Alexander Knebe, Matias Gamez-Marin, Frazer R. Pearce +6
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.…
Mapping and characterisation of cosmic filaments in galaxy cluster outskirts: strategies and forecasts for observations from simulations
Ulrike Kuchner, Alfonso Aragón-Salamanca, Frazer R. Pearce +11
Upcoming wide-field surveys are well-suited to studying the growth of galaxy clusters by tracing galaxy and gas accretion along cosmic filaments. We use hydrodynamic simulations of…
The Three Hundred Project: Backsplash galaxies in simulations of clusters
Roan Haggar, Meghan E. Gray, Frazer R. Pearce +4
In the outer regions of a galaxy cluster, galaxies may be either falling into the cluster for the first time, or have already passed through the cluster centre at some point in the…
