Distinguishing ram pressure from gravitational interactions: Applying the Size-Shape Difference method to real galaxies
Augusto E. Lassen, Rory Smith, Benedetta Vulcani +12
In dense environments, mechanisms like ram pressure stripping (RPS) and gravitational interactions can induce similar morphological features in galaxies, distinguishable only throu…
The role of supercluster filaments in shaping galaxy clusters
Raúl Baier-Soto, Yara Jaffé, Alexis Finoguenov +44
In a hierarchical CDM Universe, cosmic filaments serve as the primary channels for matter accretion into galaxy clusters, influencing the shape of their dark matter halos. We i…
Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts
Hugo Méndez-Hernández, Ciria Lima-Dias, Antonela Monachesi +54
The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these eff…
The effects on structure of a momentum coupling between dark matter and quintessence
G. N. Candlish, Y. Jaffé
Given the mysterious nature of dark matter and dark energy, and the persistent tensions in cosmological data, it is worthwhile exploring more exotic physics in the dark sector, suc…
Tracing Galaxy Evolution in infalling galaxies of Abell 496: From Starburst to Quenching
M. M. López-Gutiérrez, H. Bravo-Alfaro, P. T. Rahna +4
During the fall of late-type galaxies into clusters, they can experiment a variety of evolutionary mechanisms according their local environment. Consequently, studying the UV emiss…
CHANCES, the Chilean Cluster Galaxy Evolution Survey: Selection and initial characterisation of clusters and superclusters
Cristóbal Sifón, Alexis Finoguenov, Christopher P. Haines +43
CHANCES, the CHileAN Cluster galaxy Evolution Survey, will study the evolution of galaxies in and around 100 massive galaxy clusters from the local Universe out to , and…
