Unveiling the Milky Way with a Gaia DR3 census of OB-type stars within 2 kpc. I. Tracing local Galactic structure, massive star-forming regions and core-collapse supernova progenitors

Alexis L. Quintana, Kiril Maltsev, Eloisa Poggio +10

O- and B-type stars are young and hot, thereby serving as vital tracers of the star formation and spiral arm structure of the Milky Way. At the dusk of the \textit{Gaia} DR3 era, a…

The origin of strong -element bimodalities in FIRE simulations of Milky Way-mass galaxies

Megan Barry, Andrew Wetzel, Sarah Loebman +2

One of the Milky Way's characteristic features is a strongly bimodal distribution of -process elements, such as Mg, at fixed [Fe/H] in stellar abundances. We examine patterns i…

Understanding the Origin and Dynamical Evolution of the Unique Open Star Cluster Berkeley 20 using FIRE Simulations

Alessa I. Wiggins, Jamie R. Quinn, Micah Oeur +11

Open clusters (OCs) act as key probes that can be leveraged to constrain the formation and evolution of the Milky Way (MW)'s disk, as each has a unique chemical fingerprint and wel…

Effect of gas accretion on -element bimodality in Milky Way-mass galaxies in the FIRE-2 simulations

Hanna Parul, Jeremy Bailin, Sarah R. Loebman +3

We analyse the stellar distributions on the [Fe/H]-[Mg/Fe] plane for 11 Milky Way-mass galaxies from the FIRE-2 cosmological baryonic zoom-in simulations. Alpha-element bimodality,…

Domain adaptation in application to gravitational lens finding

Hanna Parul, Sergei Gleyzer, Pranath Reddy +1

The next decade is expected to see a tenfold increase in the number of strong gravitational lenses, driven by new wide-field imaging surveys. To discover these rare objects, effici…
