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…
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…
