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 $…
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…
The Effect of Adiabatic Compression on Dark Matter Halos and the Radial Acceleration Relation
Pengfei Li, Stacy S. McGaugh, Federico Lelli +3
We use a semi-empirical model to investigate the radial acceleration relation (RAR) in a cold dark matter (CDM) framework. Specifically, we build 80 model galaxies covering the sam…
Mass-Velocity Dispersion Relation in MaNGA Brightest Cluster Galaxies
Yong Tian, Han Cheng, Stacy S. McGaugh +2
We investigate a kinematic scaling relation between the baryonic mass and the flat velocity dispersion, i.e. mass-velocity dispersion relation (MVDR), from the brightest cluster ga…
Mass-Velocity Dispersion Relation in HIFLUGCS Galaxy Clusters
Yong Tian, Po-Chieh Yu, Pengfei Li +2
We investigate the mass-velocity dispersion relation (MVDR) in 29 galaxy clusters in the HIghest X-ray FLUx Galaxy Cluster Sample (HIFLUGCS). We measure the spatially resolved, lin…
