SchwarMAX: a GPU-friendly Schwarzschild orbit-superposition modelling framework
HanYuan Zhang, David Chemaly, Eugene Vasiliev +3
The Schwarzschild orbit-superposition method is a highly flexible dynamical modelling tool. It constrains the mass distribution of a galaxy using line-of-sight velocity and photome…

Enhanced rates of stellar radial migration in gas-rich discs at high redshift
HanYuan Zhang, Thor Tepper-GarcÃa, Vasily Belokurov +6
Radial migration and dynamical heating redistribute stars within galactic discs and thereby modify the chemo-kinematic structure of their host galaxies. Usually, these secular proc…
