Radial acceleration relation of galaxies with joint kinematic and weak-lensing data
Tobias Mistele, Stacy McGaugh, Federico Lelli +2
We combine kinematic and gravitational lensing data to construct the Radial Acceleration Relation (RAR) of galaxies over a large dynamic range. We improve on previous weak-lensing…
Distance Duality Test: The Evolution of Radio Sources Mimics a Nonexpanding Universe
Pengfei Li
Distance duality relation (DDR) marks a fundamental difference between expanding and nonexpanding Universes, as an expanding metric causes angular diameter distance smaller than lu…
Super cuspy dark matter halos of massive galaxies due to baryon-driven contraction
Pengfei Li
The interplay between dark matter (DM) and baryons has long been ignored when building galaxies semi-empirically and observationally. Here I show that baryonic gravity leads to an…
Dynamical hotness, star formation quenching and growth of supermassive black holes
Hui Hong, Huiyuan Wang, H. J. Mo +8
A stellar system is dynamically hot when its kinetic energy is dominated by random motion represented by the velocity dispersion . We use MaNGA data to obtain in…
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…
