Inferring the Mass Content of Galaxy Clusters with Satellite Kinematics and Jeans Anisotropic Modeling

The Astrophysical Journal
Satellite galaxies can be used to indicate the dynamic mass of galaxy groups and clusters. In this study, we apply the axisymmetric Jeans Anisotropic Multi-Gaussian Expansion ( JAM ) modeling to satellite galaxies in 28 galaxy clusters selected from the ...

Decoding AGN Feedback with X-arithmetic: From Morphology to Physical Mechanisms

The Astrophysical Journal
Feedback from active galactic nuclei is a key process in the evolution of massive halos in the Universe. New observational information on feedback is crucial for improving the implementation of the physics in numerical models.

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 ...
