Unveiling the time evolution of chemical abundances across the Milky Way disk with APOGEE [PDF]
Monthly notices of the Royal Astronomical Society, 2023 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 lost as a result of radial mixing processes.

Chemo-dynamical Evolution of Simulated Satellites for a Milky Way–like Galaxy
The Astrophysical JournalThe chemical abundances of Milky Way’s (MW's) satellites reflect their star formation histories (SFHs), yet, due to the difficulty of determining the ages of old stars, the SFHs of most satellites are poorly measured.

Evolution of the local spiral structure of the Milky Way revealed by open clusters [PDF]
Astronomy & Astrophysics, 2021 The structure and evolution of the spiral arms of our Milky Way are basic but long-standing questions in astronomy. In particular, the lifetime of spiral arms is still a puzzle and has not been well constrained from observations.

Warm dark matter constraints using Milky Way satellite observations and subhalo evolution modeling [PDF]
Physical Review D, 2021 Warm dark matter (WDM) can potentially explain small-scale observations that currently challenge the cold dark matter (CDM) model, as warm particles suppress structure formation due to free-streaming effects.

The effects of different Type Ia SN yields on Milky Way chemical evolution [PDF]
, 2021 We study the effect of different Type Ia SN nucleosynthesis prescriptions on the Milky Way chemical evolution. To this aim, we run detailed one-infall and two-infall chemical evolution models, adopting a large compilation of yield sets corresponding to ...

Simulating Atomic Dark Matter in Milky Way Analogs [PDF]
Astrophysical Journal Letters, 2023 Dark sector theories naturally lead to multicomponent scenarios for dark matter where a subcomponent can dissipate energy through self-interactions, allowing it to efficiently cool inside galaxies.

Connecting the young pulsars in Milky Way globular clusters with white dwarf mergers and the M81 fast radio burst [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2023 The detections of four apparently young radio pulsars in the Milky Way globular clusters are difficult to reconcile with standard neutron star formation scenarios associated with massive star evolution. Here, we discuss formation of these young pulsars

A Tale of Two Disks: Mapping the Milky Way with the Final Data Release of APOGEE [PDF]
Astrophysical Journal, 2023 We present new maps of the Milky Way disk showing the distribution of metallicity ([Fe/H]), α-element abundances ([Mg/Fe]), and stellar age, using a sample of 66,496 red giant stars from the final data release (DR17) of the Apache Point Observatory ...

The Astrophysical Journal, 2023 We have for the first time identified the early stellar disk in the Milky Way by using a combination of elemental abundances and kinematics. Using data from APOGEE DR17 and Gaia we select stars in the Mg–Mn–Al–Fe plane with elemental abundances ...
