Orbital classification in rotating bar potentials using an empirical proxy of the second integral of motion

Tian-ye Xia, Juntai Shen, John Magorrian +1

We present a novel method for classifying two-dimensional orbits in rotating bar potentials, based on an empirical proxy for the second integral of motion, Calibrated Angular Momen…

Mapping dust in the giant molecular cloud Orion A

Amery Gration, John Magorrian

The Sun is located close to the Galactic mid-plane, meaning that we observe the Galaxy through significant quantities of dust. Moreover, the vast majority of the Galaxy's stars als…

The JWST Galactic Center Survey -- A White Paper

Rainer Schoedel, Steve Longmore, Jonny Henshaw +111

The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post ma…

On the self-consistent time-dependent linearized response of stellar discs to external perturbations

Dominic Dootson, John Magorrian

We study the explicitly time-dependent response of a razor-thin axisymmetric disc to externally imposed perturbations by recasting the linearized Collisionless Boltzmann equation a…

Self-consistent modelling of the Milky Way's Nuclear Stellar Disc

Mattia C. Sormani, Jason L. Sanders, Tobias K. Fritz +14

The Nuclear Stellar Disc (NSD) is a flattened high-density stellar structure that dominates the gravitational field of the Milky Way at Galactocentric radius $30\lesssim R\lesssim…

Stellar dynamics in the periodic cube

John Magorrian

We use the problem of dynamical friction within the periodic cube to illustrate the application of perturbation theory in stellar dynamics, testing its predictions against measurem…
