Migration and kinematics in growing disc galaxies with thin and thick discs
Michael Aumer, James Binney, Ralph Schönrich
We analyse disc heating and radial migration in N-body models of growing disc galaxies with thick and thin discs. Similar to thin-disc-only models, galaxies with appropriate non-ax…
The structural evolution of galaxies with both thin and thick discs
Michael Aumer, James Binney
We perform controlled N-body simulations of disc galaxies growing within live dark matter (DM) haloes to present-day galaxies that contain both thin and thick discs. We consider tw…
Assessing distances and consistency of kinematics in Gaia/TGAS
Ralph Schönrich, Michael Aumer
We apply the statistical methods by Schoenrich, Binney & Asplund to assess the quality of distances and kinematics in the RAVE-TGAS and LAMOST-TGAS samples of Solar neighbourhood s…
Age velocity dispersion relations and heating histories in disc galaxies
Michael Aumer, James Binney, Ralph Schönrich
We analyse the heating of stellar discs by non axisymmetric structures and giant molecular clouds (GMCs) in N-body simulations of growing disc galaxies. The analysis resolves long-…
The quiescent phase of galactic disc growth
Michael Aumer, James Binney, Ralph Schönrich
We perform a series of controlled N-body simulations of growing disc galaxies within non-growing, live dark matter haloes of varying mass and concentration. Our initial conditions…
Kinematic Detection of the Galactic Nuclear Disc
Ralph Schönrich, Michael Aumer, Stuart E. Sale
We report the detection of the Galactic nuclear disc in line-of-sight kinematics of stars, measured with infrared spectroscopy from APOGEE. This stellar component of the nuclear di…
