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…
Assembly of the Intracluster Light in the Horizon-AGN Simulation
Harley J. Brown, Garreth Martin, Frazer R. Pearce +3
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…
The Three Hundred: The existence of massive dark matter-deficient satellite galaxies in cosmological simulations
Ana Contreras-Santos, Fernando Buitrago, Alexander Knebe +5
The observation of a massive galaxy with an extremely low dark matter content (i.e. NGC 1277) has posed questions about how such objects form and evolve in a hierarchical universe.…
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…
Correcting for the overabundance of low-mass quiescent galaxies in semi-analytic models
Jimi E. Harrold, Omar Almaini, Frazer R. Pearce +1
We compare the L-Galaxies semi-analytic model to deep observational data from the UKIDSS Ultra Deep Survey (UDS) across the redshift range . We find that the over-abun…
The localization of galaxy groups in close proximity to galaxy clusters using cosmic web nodes
Daniel J. Cornwell, Ulrike Kuchner, Meghan E. Gray +4
We investigate the efficacy of using the cosmic web nodes identified by the DisPerSE topological filament finder to systematically identify galaxy groups in the infall regions arou…
