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…
The Next Generation Virgo Cluster Survey (NGVS). II. A Catalog of Galaxies in the Virgo Cluster
Laura Ferrarese, Patrick Cote, Lauren A. MacArthur +51
The Next Generation Virgo Cluster Survey (NGVS) is a deep, high resolution imaging campaign that used the 1 deg MegaCam instrument on the Canada-France-Hawaii Telescope to carr…
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…
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…
