Mapping parameters of idealised hydrodynamic galaxy simulations to bar properties: a case study with the RAMSES code
Srikanth T. Nagesh, Benoit Famaey, Jonathan Freundlich +4
Cosmological simulations with high spatial resolution often struggle to reproduce the observed fraction of galactic bars across redshift and may produce bars that are too short. To…
Radial and azimuthal gradients of the moving groups in Gaia DR3: The slow/fast bar degeneracy problem
Marcel Bernet, Pau Ramos, Teresa Antoja +2
The structure and dynamics of the central bar of the Milky Way are still under debate whilst being fundamental ingredients for the evolution of our Galaxy. The recent Gaia DR3 offe…
The Pristine Inner Galaxy Survey (PIGS) VIII: Characterising the orbital properties of the ancient, very metal-poor inner Milky Way
Anke Ardern-Arentsen, Giacomo Monari, Anna B. A. Queiroz +19
The oldest stars in the Milky Way (born in the first few billion years) are expected to have a high density in the inner few kpc, spatially overlapping with the Galactic bulge. We…
Charting the Galactic acceleration field II. A global mass model of the Milky Way from the STREAMFINDER Atlas of Stellar Streams detected in Gaia DR3
Rodrigo Ibata, Khyati Malhan, Wassim Tenachi +17
We present an atlas and follow-up spectroscopic observations of 87 thin stream-like structures detected with the STREAMFINDER algorithm in Gaia DR3, of which 29 are new discoveries…
Could very low-metallicity stars with rotation-dominated orbits have been shepherded by the bar?
Zhen Yuan, Chengdong Li, Nicolas F. Martin +11
The most metal-poor stars (e.g. [Fe/H] ) are the ancient fossils from the early assembly epoch of our Galaxy, very likely before the formation of the thick disc. Recent s…
Exploring the impact of a rapidly decelerating bar on transforming bulge orbits into disc-like orbits
Chengdong Li, Zhen Yuan, Giacomo Monari +7
The most metal-poor tail of the Milky Way ([Fe/H] 2.5) contains a population of stars with very prograde planar orbits, which is puzzling in both their origin and evoluti…
