The edge of the Milky Way's star-forming disc: Evidence from a 'U-shaped' stellar age profile
Karl Fiteni, Stuart Robert Anderson, Victor. P. Debattista +7
We leveraged reliable age and distance estimates from LAMOST-DR3 and APOGEE-DR17+AstroNN combined with \gaia\ data to perform a detailed analysis of the stellar age distribution in…
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…
Azimuthal metallicity variations, spiral structure, and the failure of radial actions based on assuming axisymmetry
Victor P. Debattista, Tigran Khachaturyants, Joao A. S. Amarante +3
We study azimuthal variations in the mean stellar metallicity, <[Fe/H]>, in a self-consistent, isolated simulation in which all stars form out of gas. We find <[Fe/H]> variations c…
NANCY: Next-generation All-sky Near-infrared Community surveY
Jiwon Jesse Han, Arjun Dey, Adrian M. Price-Whelan +206
The Nancy Grace Roman Space Telescope is capable of delivering an unprecedented all-sky, high-spatial resolution, multi-epoch infrared map to the astronomical community. This oppor…
The pattern speeds of vertical breathing waves
Tigran Khachaturyants, Victor P. Debattista, Soumavo Ghosh +2
We measure and compare the pattern speeds of vertical breathing, vertical bending, and spiral density waves in two isolated N-body+SPH simulations, using windowed Fourier transform…
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…
How stars formed in warps settle into (and contaminate) thick discs
Tigran Khachaturyants, Leandro Beraldo e Silva, Victor P. Debattista
In recent years star formation has been discovered in the Milky Way's warp. These stars formed in the warp (warp stars) must eventually settle into the plane of the disc. We use an…
