The phase spiral in Gaia DR3
T. Antoja, P. Ramos, B. García-Conde +3
We aim to study the phase spiral in the Milky Way (MW) with Gaia DR3. We used an edge detection algorithm to find the border of the phase spiral, allowing us to robustly quantify i…
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…
Kinematic analysis of the Large Magellanic Cloud using Gaia DR3
Ó. Jiménez-Arranz, M. Romero-Gómez, X. Luri +6
Context: The high quality of the Gaia mission data is allowing to study the internal kinematics of the Large Magellanic Cloud (LMC) in unprecedented detail, providing insights on t…
Spiral-like features in the disc revealed by Gaia DR3 radial actions
P. A. Palicio, A. Recio-Blanco, E. Poggio +3
We aim to explore the actions of the new Gaia DR3 astrometry to find structures in the Galactic disc. We compute the actions and the orbital parameters of the Gaia DR3 stars with f…
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…
Gaia Data Release 3: Catalogue Validation
C. Babusiaux, C. Fabricius, S. Khanna +40
The third gaia data release (DR3) provides a wealth of new data products. The early part of the release, Gaia EDR3, already provided the astrometric and photometric data for nearly…
