Turning Points in the Age-Metallicity Relations -- Created by Late Satellite Infall and Enhanced by Radial Migration
Yuxi Lu, Melissa K. Ness, Tobias Buck +1
The present-day Age-Metallicity Relation (AMR) is a record of the star formation history of the Galaxy, as this traces the chemical enrichment of the gas over time. We use a zoomed…
Predicting resolved galaxy properties from photometric images using convolutional neural networks
Tobias Buck, Steffen Wolf
Multi-band images of galaxies reveal a huge amount of information about their morphology and structure. However, inferring properties of the underlying stellar populations such as…
A first estimate of the Milky Way dark matter halo spin
A. Obreja, T. Buck, A. V. Macciò
The spin, , of dark matter (DM) halos in cosmological simulations follows a log normal distribution and has little correlation with galaxy observables. As such, there is current…
NIHAO-LG: The uniqueness of Local Group dwarf galaxies
Nikhil Arora, Andrea V. Macció, Stéphane Courteau +8
Recent observational and theoretical studies of the Local Group (LG) dwarf galaxies have highlighted their unique star-formation history, stellar metallicity, gas content, and kine…
The GALAH Survey: Chemical tagging and chrono-chemodynamics of accreted halo stars with GALAH+ DR3 and eDR3
Sven Buder, Karin Lind, Melissa K. Ness +27
Since the advent of astrometry, it is possible to identify massive accreted systems within the Galaxy through their unique dynamical signatures. One such system, -Saus…
Tracing birth properties of stars with abundance clustering
Bridget L. Ratcliffe, Melissa K. Ness, Tobias Buck +4
To understand the formation and evolution of the Milky Way disk, we must connect its current properties to its past. We explore hydrodynamical cosmological simulations to investiga…
