LMC Stars and Where to Find Them: Inferring Birth Radii for External Galaxies
Yuxi, Lu, Tobias Buck +5
It is well known that stars move away from their birth location over time via radial migration. This dynamical process makes computing the correct chemical evolution, e.g., metalli…
Why does the Milky Way have a bar?
Sergey Khoperskov, Ivan Minchev, Matthias Steinmetz +3
There is no doubt that the Milky Way is a barred galaxy; however, factors that establish its prominent morphology remain largely elusive and poorly comprehended. In this work, we a…
Chemical clocks and their time zones: understanding the [s/Mg]--age relation with birth radii
Bridget Ratcliffe, Ivan Minchev, Gabriele Cescutti +5
The relative enrichment of s-process to -elements ([s/]) has been linked with age, providing a potentially useful avenue in exploring the Milky Way's chemical evolution. Howe…
KPM: A Flexible and Data-Driven K-Process Model for Nucleosynthesis
Emily J. Griffith, David W. Hogg, Julianne J. Dalcanton +4
The element abundance pattern found in Milky Way disk stars is close to two-dimensional, dominated by production from one prompt process and one delayed process. This simplicity is…
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 impact of early massive mergers on the chemical evolution of Milky Way-like galaxies: insights from NIHAO-UHD simulations
Tobias Buck, Aura Obreja, Bridget Ratcliffe +4
Recent observations of the Milky Way (MW) found an unexpected steepening of the star-forming gas metallicity gradient around the time of the Gaia-Sausage-Enceladus (GSE) merger eve…
Unveiling the time evolution of chemical abundances across the Milky Way disk with APOGEE
Bridget Ratcliffe, Ivan Minchev, Friedrich Anders +12
Chemical abundances are an essential tool in untangling the Milky Way's enrichment history. However, the evolution of the interstellar medium abundance gradient with cosmic time is…
Spectroscopic age estimates for APOGEE red-giant stars: Precise spatial and kinematic trends with age in the Galactic disc
F. Anders, P. Gispert, B. Ratcliffe +12
Over the last few years, many studies have found an empirical relationship between the abundance of a star and its age. Here we estimate spectroscopic stellar ages for 178 825 red-…
