A new Gaia census of OB associations within 1 kpc
Alexis L. Quintana, Nicholas J. Wright, Lilly A. Kormann +6
OB associations are primordial tracers of star formation and Galactic structure. Originally defined about 80 years ago, their historical membership lists have been superseded thank…
Fuzzy dark matter dynamical friction: stalling of globular clusters induced by dynamical heatings
Adrian Szpilfidel, Pierre Boldrini, Jo Bovy +1
We present a new implementation of fuzzy dark matter (FDM) dynamical friction within the galpy framework, enabling orbital integrations of globular clusters (GCs) across a broad ra…
Chemical decoding of kinematic substructures in the Galactic halo
A. Mori, P. Di Matteo, S. Salvadori +4
In the hierarchical assembly framework, the accretion history of the Milky Way is crucial to understand its evolution. However, in massive mergers, integrals of motion are not stri…
Evidence of Gaia Enceladus experiencing at least two passages around the Milky Way
Ása Skúladóttir, Heitor Ernandes, Diane K. Feuillet +4
One of the major recent breakthroughs has been the discovery of the last Major Merger to happen in the history of the Milky Way. Around 10 Gyr ago the galaxy Gaia Enceladus, with e…
Turbulent gas-rich discs at high redshift: origin of thick stellar discs through 3D 'baryon sloshing'
Joss Bland-Hawthorn, Thor Tepper-Garcia, Oscar Agertz +8
In response to recent observations from JWST and ALMA, we explore a new class of dynamically self-consistent models using our AGAMA/Ramses hydrodynamic N-body framework (Nexus) tha…
