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…
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…
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…
