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…
Impact of the Galactic bar on tidal streams within the Galactic disc: The case of the tidal stream of the Hyades
Guillaume F. Thomas, Benoit Famaey, Giacomo Monari +5
Tidal streams of disrupted clusters are routinely detected in the halo of the Milky Way. It was recently shown that tidal streams of open clusters can now also be detected within t…
Gaia DR3 features of the phase spiral and its possible relation to internal perturbations
Chengdong Li, Arnaud Siebert, Giacomo Monari +2
Disc stars from the Gaia DR3 RVS catalogue are selected to explore the phase spiral as a function of position in the Galaxy. The data reveal a two-armed phase spiral pattern in the…
