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…
From ridges to manifolds: 3D characterization of the moving groups in the Milky Way disc
Marcel Bernet, Pau Ramos, Teresa Antoja +4
The stellar velocity distribution in the Solar Neighbourhood displays kinematic substructures, which are possibly signatures of the bar and spiral arms of the Milky Way and of prev…
A new resonance-like feature in the outer disc of the Milky Way
Ronald Drimmel, Shourya Khanna, Elena D'Onghia +18
Modern astrometric and spectroscopic surveys have revealed a wealth of structure in the phase space of stars in the Milky Way, with evidence of resonance features and non-equilibri…
The disturbed outer Milky Way disc
Paul J. McMillan, Jonathan Petersson, Thor Tepper-Garcia +9
The outer parts of the Milky Way's disc are significantly out of equilibrium. Using only distances and proper motions of stars from Gaia's Early Data Release 3, in the range |b|<10…
Tidally induced spiral arm wraps encoded in phase space
T. Antoja, P. Ramos, F. López-Guitart +3
We study the dynamics of tidally induced spiral arms in our Galaxy in the context of its encounters with Sagittarius. We built toy models of the interaction between a host and a sa…
Revisiting a disky origin for the faint branch of the Sagittarius stellar stream
Pierre-Antoine Oria, Rodrigo Ibata, Pau Ramos +2
We investigate ways to produce the bifurcation observed in the stellar stream of the Sagittarius dwarf galaxy (Sgr). Our method consists in running -body simulations of Sgr fall…
The Pristine Inner Galaxy Survey (PIGS) IV: A photometric metallicity analysis of the Sagittarius dwarf spheroidal galaxy
Sara Vitali, Anke Arentsen, Else Starkenburg +15
We present a comprehensive metallicity analysis of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) using photometry. We base our member selection on EDR3…
