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…

HI terminal velocity curves -- Lessons learned from N-body/hydrodynamic `surrogate' models of the Milky Way
Hillary Davis, Thor Tepper-Garcia, Naomi McClure-Griffiths +2
The development of an N-body/hydrodynamic `surrogate' model of the Milky Way (MW) - a model that resembles the MW in several key aspects after many Gyrs of evolution - would be ext…
