Orbital tori for non-axisymmetric galaxies
James Binney
Our Galaxy's bar makes the Galaxy's potential distinctly non-axisymmetric. All orbits are affected by non-axisymmetry, and significant numbers are qualitatively changed by being tr…
Is the Milky Way still breathing? RAVE-Gaia streaming motions
I. Carrillo, I. Minchev, G. Kordopatis +26
We use data from the Radial Velocity Experiment (RAVE) and the Tycho-Gaia astrometric solution catalogue (TGAS) to compute the velocity fields yielded by the radial (VR), azimuthal…
Distribution functions for resonantly trapped orbits in the Galactic disc
Giacomo Monari, Benoit Famaey, Jean-Baptiste Fouvry +1
The present-day response of a Galactic disc stellar population to a non-axisymmetric perturbation of the potential has previously been computed through perturbation theory within t…
Improved distances and ages for stars common to TGAS and RAVE
Paul J. McMillan, Georges Kordopatis, Andrea Kunder +15
We combine parallaxes from the first Gaia data release with the spectrophotometric distance estimation framework for stars in the fifth RAVE survey data release. The combined dista…
A theoretical explanation for the Central Molecular Zone asymmetry
Mattia C. Sormani, Robin G. Tress, Matthew Ridley +5
It has been known for more than thirty years that the distribution of molecular gas in the innermost 300 parsecs of the Milky Way, the Central Molecular Zone, is strongly asymmetri…
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…
Self-consistent Modelling of the Milky Way using Gaia data
David R Cole, James Binney
Angle/action based distribution function (DF) models can be optimised based on how well they reproduce observations thus revealing the current matter distribution in the Milky Way.…
Self-consistent modelling of our Galaxy with Gaia data
James Binney
Galaxy models are fundamental to exploiting surveys of our Galaxy. There is now a significant body of work on axisymmetric models. A model can be defined by giving the DF of each m…
Modelling the Milky Way's globular cluster system
James Binney, Leong Khim Wong
We construct a model for the Galactic globular cluster system based on a realistic gravitational potential and a distribution function (DF) analytic in the action integrals. The DF…
The angular momentum of cosmological coronae and the inside-out growth of spiral galaxies
Gabriele Pezzulli, Filippo Fraternali, James Binney
Massive and diffuse haloes of hot gas (coronae) are important intermediaries between cosmology and galaxy evolution, storing mass and angular momentum acquired from the cosmic web…
