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 Galactic Bulge exploration IV.: RR~Lyrae stars as traces of the Galactic bar -- 3D and 5D analysis, extinction variation
Z. Prudil, A. Kunder, L. Beraldo e Silva +10
We created new reddening maps and derived new extinction laws from visual to near-infrared passbands using improved RR~Lyrae period-absolute magnitude-metallicity relations, thus e…
The Profiles of Bars in Spiral Galaxies
Peter Erwin, Victor P. Debattista, Stuart Robert Anderson
We present an analysis of major-axis surface-brightness profiles of bars in a volume-limited sample of 182 barred spiral galaxies, using Spitzer 3.6 micron images. Unlike most prev…
Orbital support and evolution of flat profiles of bars (shoulders)
Leandro Beraldo e Silva, Victor P. Debattista, Stuart R. Anderson +4
Many barred galaxies exhibit upturns (shoulders) in their bar major-axis density profile. Simulation studies have suggested that shoulders are supported by looped orbits, occ…
The interplay between accretion, galaxy downsizing and the formation of box/peanut bulges in TNG50
Stuart Robert Anderson, Steven Gough-Kelly, Victor P. Debattista +6
From the TNG50 cosmological simulation we build a sample of 191 well-resolved barred galaxies with a stellar mass at . We search for box/peanut bulges (BPs…
Testing for relics of past strong buckling events in edge-on galaxies: Simulation predictions and data from SG
V. Cuomo, V. P. Debattista, S. Racz +7
The short-lived buckling instability is responsible for the formation of at least some box/peanut (B/P) shaped bulges, which are observed in most massive, , barred galaxies. N…
The secular growth of bars revealed by flat (peak + shoulders) density profiles
Stuart Robert Anderson, Victor P. Debattista, Peter Erwin +3
The major-axis density profiles of bars are known to be either exponential or 'flat'. We develop an automated non-parametric algorithm to detect flat profiles and apply it to a sui…
Predicted Trends in Milky Way Bulge Proper Motion Rotation Curves: future Prospects for HST and LSST
Steven Gough-Kelly, Victor P. Debattista, William I. Clarkson +5
We use an -body+smoothed particle hydrodynamics simulation of an isolated barred galaxy to study the age dependence of bulge longitudinal proper motion () rotation curves.…
