Mass models of galaxy clusters from a non-parametric weak-lensing reconstruction
Tobias Mistele, Federico Lelli, Stacy McGaugh +2
We study the CLASH sample of galaxy clusters using a new deprojection method for weak gravitational lensing observations. This method is non-parametric, allowing us to infer mass p…

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…
