Simulating the Milky Way bar and bulge with an initially Sérsic disc
N. Deg, Victor P. Debattista, Lawrence Widrow +3
We model the formation of a bar plus box/peanut bulge (BP bulge) component in a Milky Way-like disc galaxy using simulations of isolated multi-component systems that evolve from eq…

The chemical and spatial variations of the bulge's velocity ellipsoids
Luis M. San Martin Fernandez, Steven Gough-Kelly, Victor P. Debattista +4
We study the velocity ellipsoids in an -bodySPH simulation of a barred galaxy which forms a bar with a BP bulge. We focus on the 2D kinematics, and quantify the velocity elli…
