The empirical laws of galaxy dynamics: from gas kinematics to weak lensing

Federico Lelli, Tobias Mistele, Stacy S. McGaugh +2

Galaxies obey a set of strict dynamical laws, which imply a close coupling between the visible matter (stars and gas) and the observed dynamics (set by dark matter in the standard…

Indefinitely Flat Circular Velocities and the Baryonic Tully-Fisher Relation from Weak Lensing

Tobias Mistele, Stacy McGaugh, Federico Lelli +2

We use a new deprojection formula to infer the gravitational potential around isolated galaxies from weak gravitational lensing. The results imply circular velocity curves that rem…

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…

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…
