Milky Way Mapper decoded abundances -- II: From patterns to paths

Melissa K. Ness, Sarah Aquilina, Jennifer Mead +15

The element abundances of Milky Way disc stars encode entangled imprints of multiple enrichment processes, making it difficult to uncover the underlying chemical evolution. Here we…

Milky Way Mapper decoded abundances -- I. Shared disc enrichment patterns

Melissa K. Ness, Sarah Aquilina, Jennifer Mead +15

Elemental abundances in the Milky Way disc trace its star-formation and enrichment history, but predicting these abundances from theory is limited by uncertain nucleosynthetic yiel…

Phase spirals across galactic disks I: Exploring dynamical influences on winding

Kiyan Tavangar, Kathryn V. Johnston, Jason A. S. Hunt +4

The vertical phase-space spirals in the Milky Way are clear evidence of disequilibrium. However, they are challenging to study because phase mixing signals evolve under the influen…

The dark matter wake of a galactic bar revealed by multichannel Singular Spectral Analysis

Jason A. S. Hunt, Michael S. Petersen, Martin D. Weinberg +7

The Milky Way is known to contain a stellar bar, as are a significant fraction of disc galaxies across the universe. Our understanding of bar evolution, both theoretically and thro…

The phase spiral's origin and evolution: indications from its varying properties across the Milky Way disk

Axel Widmark, Kiyan Tavangar, Josh Kalish +2

The phase spiral is a perturbation to the vertical phase-space distribution of stars in the Milky Way disk. We study the phase spiral's properties and how they vary with spatial po…

Using simulation based inference on tidally perturbed dwarf galaxies: the dynamics of NGC205

Axel Widmark, Kathryn V. Johnston

We develop a novel approach to performing precision inference on tidally perturbed dwarf galaxies. We use a Bayesian inference framework of implicit likelihood inference, previousl…
