Dark matter spiral arms in Milky Way-like halos
Marcel Bernet, Pau Ramos, Teresa Antoja +9
The coupling between the dark matter (DM) halo and the stellar disc is a key factor in galactic evolution. While the interaction between structures like the Galactic bar and DM hal…
Radial and azimuthal gradients of the moving groups in Gaia DR3: The slow/fast bar degeneracy problem
Marcel Bernet, Pau Ramos, Teresa Antoja +2
The structure and dynamics of the central bar of the Milky Way are still under debate whilst being fundamental ingredients for the evolution of our Galaxy. The recent Gaia DR3 offe…
Structure, kinematics and time evolution of the Galactic Warp from Classical Cepheids
Mauro Cabrera-Gadea, Cecilia Mateu, Pau Ramos +11
The warp is a well-known undulation of the Milky Way disc. Its structure has been widely studied, but only since Gaia DR2 has it been possible to reveal its kinematic signature bey…
JASMINE: Near-Infrared Astrometry and Time Series Photometry Science
Daisuke Kawata, Hajime Kawahara, Naoteru Gouda +86
Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a planned M-class science space mission by the Institute of Space and Astronautical Science, the Japan Aero…
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…
Phase spirals in cosmological simulations of Milky Way-size galaxies
Begoña García-Conde, Santi Roca-Fàbrega, Teresa Antoja +2
We study the vertical perturbations in the galactic disc of the Milky Way-size high-resolution hydrodynamical cosmological simulation named GARROTXA. We detect phase spirals in the…
