Identifying backsplash galaxies using machine learning
Roan Haggar, Elizaveta Sazonova, Cameron R. Morgan +5
The paper presents a machine‑learning model trained on The Three Hundred cluster simulations that can identify backsplash galaxies in observations, achieving about 70% purity/compl…
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…
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…
No Evidence of Asymmetrically Enhanced Star Formation in Infalling Galaxies in UNIONS
Lauren M. Foster, Laura C. Parker, Stephen Gwyn +5
Ram pressure stripping is a well-known environmental quenching mechanism that removes gas from galaxies infalling into groups and clusters. In some extreme examples of ram pressure…
