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

Abstract 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 Gaia DR3 era, a high-confidence and accurate catalogue appears timely. We have characterized 105,971 OB-type stars...

The Role of Dark Matter in Driving Disk Perturbations: Application to LMC–SMC-like Galaxy Interactions

Abstract Dark matter (DM) models predict that satellite galaxies distort their host’s DM halo. As such, both the satellite and the distorted halo can perturb the host’s stellar disk. The LMC–SMC system is a nearby ∼1:10 mass ratio binary with a well-constrained orbit and well-cha...
