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…

The Three Hundred: Gas Properties Outside of Galaxy Cluster with the WHIM Contribution and Detection

Renjie Li, Weiguang Cui, Ang Liu +4

We investigate the physical properties and detectability of warm-hot intergalactic medium (WHIM) gas with temperatures in the range K around galaxy clusters using simu…

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…
