ED-2: a cold but not so narrow stellar stream crossing the Solar neighbourhood
E. Balbinot, A. Helmi, T. Callingham +3
ED-2 is a stellar stream identified as a compact group in integrals of motion space in a local sample of halo stars from the third Gaia data release. Here we investigate its nature…
A 3D view of dwarf galaxies with Gaia and VLT/FLAMES I. The Sculptor dwarf spheroidal
Eline Tolstoy, Ása Skúladóttir, Giuseppina Battaglia +12
We present a new homogeneous survey of VLT/FLAMES LR8 line-of-sight radial velocities (vlos) for 1604 resolved red giant branch stars in the Sculptor dwarf spheroidal galaxy. In ad…
Hidden deep in the halo: selection of a reduced proper motion halo catalogue and mining retrograde streams in the velocity space
Akshara Viswanathan, Else Starkenburg, Helmer H. Koppelman +3
The Milky Way halo is one of the few galactic haloes that provides a unique insight into galaxy formation by resolved stellar populations. Here, we present a catalogue of 47…
Improving metallicity estimates for very metal-poor stars in the Gaia DR3 GSP-Spec catalog
Tadafumi Matsuno, Else Starkenburg, Eduardo Balbinot +1
The Gaia DR3 GSP-Spec parameters, including metallicity, for VMP stars suffer from parameter degeneracy due to a lack of information in their spectra. Furthermore, the recommended…
The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation
Shoko Jin, Scott C. Trager, Gavin B. Dalton +212
WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree…
The Gaia DR3 view of dynamical substructure in the stellar halo near the Sun
Emma Dodd, Thomas M. Callingham, Amina Helmi +4
The debris from past merger events is expected and, to some extent, known to populate the stellar halo near the Sun. We aim to identify and characterise such merger debris using Ga…
