The Baryonic Faber-Jackson Relation and Fundamental Plane of Galaxy Groups, Elliptical Galaxies, and Dwarf Galaxies
Yong Tian, Federico Lelli, Marcel S. Pawlowski +7
The baryonic Faber-Jackson relation (BFJR) links the baryonic mass of pressure-supported systems to their mean velocity dispersion. For elliptical galaxies, the BFJR is thought to…
Probing the nature of gravity in the low-acceleration limit: wide binaries of extreme separations with perspective effects
Youngsub Yoon, Yong Tian, Kyu-Hyun Chae
Recent statistical analyses of wide binaries have revealed a boost in gravitational acceleration with respect to the prediction by Newtonian gravity at low internal accelerations $…
Gas thermodynamics meets galaxy kinematics: Joint mass measurements for eROSITA galaxy clusters
Pengfei Li, Ang Liu, Matthias Kluge +13
The mass of galaxy clusters is a critical quantity for probing cluster cosmology and testing theories of gravity, but its measurement could be biased given assumptions are inevitab…
Examining Baryonic Faber-Jackson Relation in Galaxy Groups
Pradyumna Sadhu, Yong Tian
We investigate the Baryonic Faber-Jackson Relation (BFJR), examining the correlation between baryonic mass and velocity dispersion in galaxy groups and clusters. Originally analyse…
A Distinct Radial Acceleration Relation across Brightest Cluster Galaxies and Galaxy Clusters
Yong Tian, Chung-Ming Ko, Pengfei Li +2
Recent studies reveal a radial acceleration relation (RAR) in galaxies, which illustrates a tight empirical correlation connecting the observational acceleration and the baryonic a…
Measuring galaxy cluster mass profiles into the low acceleration regime with galaxy kinematics
Pengfei Li, Yong Tian, Mariana P. Júlio +7
We probe the dynamical mass profiles of 10 galaxy clusters from the HIghest X-ray FLUx Galaxy Cluster Sample (HIFLUGCS) using galaxy kinematics. We numerically solve the spherical…
