Winding, Unwinding, Rewinding the Gaia Phase Spiral

Neige Frankel, Marcin Semczuk, Teresa Antoja +10

The Gaia Space Satellite has transformed the field of Galactic Dynamics by collecting 6D phase space information for hundreds of millions of stars. In 2018, it enabled the discover…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Galactic Archaeology from the Northern Sky

Borja Anguiano, David Valls-Gabaud, Guillaume F. Thomas +7

By the 2040s--50s, facilities such as \emph{Gaia}, WEAVE, 4MOST, Rubin, \emph{Euclid}, \emph{Roman}, and the ESO ELT will have transformed our global view of the Milky Way. Yet key…

Delayed phase mixing in the self-gravitating Galactic disc

T. Asano, T. Antoja

The Gaia phase spiral is considered to work as a dynamical clock for dating past perturbations, but some of the previous studies neglected the disc's self-gravity, potentially bias…

Analogues of the Milky Way-Sagittarius interaction in the TNG50: effect on the Milky Way

Marcin Semczuk, Teresa Antoja, Alexandra Girón-Soto +1

The Sagittarius Dwarf Galaxy is undoubtedly being disrupted in the tidal field of the Milky Way. The Milky Way disc is also found to be in a state of disequilibrium. The role of th…

Spiral arms across stellar populations in simulations via the local dimension method

J. Ardèvol, M. Semczuk, T. Antoja +3

Context. The origin and nature of spiral arms remain unclear. Star forming regions and young stars are generally strongly associated to the spiral structure, but there are few quan…

Formation of the Two-Armed Phase Spiral from Multiple External Perturbations

Junxian Lin, Zhao-Yu Li, Rui Guo +3

Recent studies using the Gaia DR3 data have revealed a two-armed phase spiral in the phase space in the inner disk. In this study, we present new features of the two-armed…
