Rediscovering the Milky Way with an orbit superposition approach and APOGEE data V. The disc growth and history of star formation
Bridget Ratcliffe, Sergey Khoperskov, Nathan Lee +8
The Milky Way's (MW's) star formation history (SFH) offers insight into the chronology of its assembly and the mechanisms driving its structural development. In this study, we pres…
Bar-spiral interaction produces radial migration and star formation bursts
Léa Marques, Ivan Minchev, Bridget Ratcliffe +8
Central bars and spirals are known to strongly impact the evolution of their host galaxies, both in terms of dynamics and star formation. Their typically different pattern speeds c…
Rediscovering the Milky Way with orbit superposition approach and APOGEE data III. Panoramic view of the bulge
Sergey Khoperskov, Paola Di Matteo, Matthias Steinmetz +9
The innermost parts of the Milky Way (MW) are very difficult to observe due to the high extinction along the line of sight, especially close to the disc mid-plane. However, this re…
Rediscovering the Milky Way with orbit superposition approach and APOGEE data II. Chrono-chemo-kinematics of the disc
Sergey Khoperskov, Matthias Steinmetz, Misha Haywood +9
The stellar disc is the dominant luminous component of the Milky Way (MW). Although our understanding of its structure is rapidly expanding due to advances in large-scale stellar s…
Rediscovering the Milky Way with orbit superposition approach and APOGEE data I. Method validation
Sergey Khoperskov, Glenn van de Ven, Matthias Steinmetz +9
We introduce a novel orbit superposition method designed to reconstruct the stellar density structure, kinematics, and chemical abundance distribution of the entire Milky Way by le…
The chemical evolution of the Milky Way thin disk using solar twins
Anastasiia Plotnikova, Lorenzo Spina, Bridget Ratcliffe +2
In this study we address whether the age--metallicity relation (AMR) deviates from the expected trend of metallicity increasing smoothly with age. We also show the presence (or abs…
Effects of secular growth and mergers on the evolution of metallicity gradients and azimuthal variations in a Milky Way-like galaxy
Florent Renaud, Bridget Ratcliffe, Ivan Minchev +4
We analyze the evolution of the radial profiles and the azimuthal variations of the stellar metallicities from the Vintergatan simulation of a Milky Way-like galaxy. We find that n…
Evolution of the radial ISM metallicity gradient in the Milky Way disk since redshift
Bridget Ratcliffe, Sergey Khoperskov, Ivan Minchev +5
Recent works identified a way to recover the time evolution of a galaxy's disk metallicity gradient from the shape of its age--metallicity relation. However, the success of the met…
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-…
There is No Place Like Home -- Finding Birth Radii of Stars in the Milky Way
Yuxi Lu, Ivan Minchev, Tobias Buck +6
Stars move away from their birthplaces over time via a process known as radial migration, which blurs chemo-kinematic relations used for reconstructing the Milky Way (MW) formation…
The chemical enrichment of the Milky Way disk evaluated using conditional abundances
Bridget Ratcliffe, Melissa Ness
Chemical abundances of stars in the Milky Way disk are empirical tracers of its enrichment history. However, they capture joint-information that is valuable to disentangle. In this…

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…
Tracing the assembly of the Milky Way's disk through abundance clustering
Bridget L. Ratcliffe, Melissa K. Ness, Kathryn V. Johnston +1
A major goal in the field of galaxy formation is to understand the formation of the Milky Way's disk. The first step toward doing this is to empirically describe its present state.…
