Swarming in stellar streams: Unveiling the structure of the Jhelum stream with ant colony-inspired computation

Petra Awad, Marco Canducci, Eduardo Balbinot +8

The halo of the Milky Way galaxy hosts multiple dynamically coherent substructures known as stellar streams that are remnants of tidally disrupted systems such as globular clusters…

Stellar Metallicities and Gradients in the Isolated, Quenched Low-Mass Galaxy Tucana

Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg +10

We measure the metallicities of 374 red giant branch (RGB) stars in the isolated, quenched dwarf galaxy Tucana using Hubble Space Telescope (HST) narrow-band (F395N) Calcium H & K…

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…

Probing the early Milky Way with GHOST spectra of an extremely metal-poor star in the Galactic disk

Anya Dovgal, Kim A. Venn, Federico Sestito +31

Pristine_183.6849+04.8619 (P1836849) is an extremely metal-poor ([Fe/H]) star on a prograde orbit confined to the Galactic disk. Such stars are rare and may have their…

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…
