Luminosity segregation in galaxy clusters as an indication of dynamical evolution [PDF]

Theoretical models describing the dynamical evolution of self-gravitating systems predict a spatial mass segregation for more evolved systems, with the more massive objects concentrated toward the center of the configuration. From the observational point

Exploiting Machine Learning and Disequilibrium in Galaxy Clusters to Obtain a Mass Profile

The Astrophysical Journal Letters
We use 3D k -means clustering to characterize galaxy substructure in the A2146 cluster of galaxies ( z = 0.2343). This method objectively characterizes the cluster’s substructure using projected position and velocity data for 67 galaxies within a 2.305 ...

Formation Channels of Diffuse Lights in Groups and Clusters over Time

The Astrophysical Journal
We explore the formation of the intragroup light and intracluster light, representing diffuse lights within groups and clusters, from the point that z = 1.5.

Galaxy Cluster Constraints on Extensions of Modified Gravity

The Astrophysical Journal
Modified Newtonian dynamics (MOND) has achieved notable success in explaining galaxy-scale phenomena and has made several unexpected, a priori predictions that align with observations.
