Radial migration in numerical simulations of Milky Way-sized galaxies
Robert J. J. Grand, Daisuke Kawata
We show that in N-body simulations of isolated spiral discs, spiral arms appear to transient, recurring features that co-rotate with the stellar disc stars at all radii. As a conse…
Spiral arm kinematics for Milky Way stellar populations
S. Pasetto, G. Natale, D. Kawata +3
We present a new theoretical population synthesis model (the Galaxy Model) to examine and deal with large amounts of data from surveys of the Milky Way and to decipher the present…
Spiral and bar driven peculiar velocities in Milky Way sized galaxy simulations
Robert J. J. Grand, Jo Bovy, Daisuke Kawata +5
We investigate the kinematic signatures induced by spiral and bar structure in a set of simulations of Milky Way-sized spiral disc galaxies. The set includes test particle simulati…
A PRIMAL view of the Milky Way, made possible by Gaia and M2M modelling
Jason A. S. Hunt, Daisuke Kawata
We have developed our original made-to-measure (M2M) algorithm, PRIMAL, with the aim of modelling the Galactic disc from upcoming Gaia data. From a Milky Way like N-body disc galax…
The stellar kinematics of co-rotating spiral arms in Gaia mock observations
Jason A. S. Hunt, Daisuke Kawata, Robert J. J. Grand +3
We have observed an N-body/Smoothed Particle Hydrodynamics simulation of a Milky Way like barred spiral galaxy. We present a simple method that samples N-body model particles into…
