Tree-ring structure of Galactic bar resonance in N-body simulations
Rimpei Chiba, Michiko Fujii, Junichi Baba +2
We study the structure and evolution of the galactic bar's resonant phase-space in self-consistent N-body simulations of the Milky Way, with and without perturbations from the Sagi…
Galaxy fly-bys sustain bar-halo friction and bar slowdown in disk galaxies
Rumi Kodama, Rimpei Chiba, Tetsuro Asano +2
Bars in disk galaxies slow down as they transfer their angular momentum to their dark matter halo via dynamical friction from near-resonant orbits. This bar-halo dynamical friction…
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…
Galactic echoes
Rimpei Chiba, Jupiter Ding, Chris Hamilton +2
Gaia has revealed a variety of substructures in the phase space of stars in the Solar neighborhood, including the vertical `Snail' in space. Such substructures are often…
Galaxy Zoo CEERS: Bar fractions up to z~4.0
Tobias Géron, R. J. Smethurst, Hugh Dickinson +22
We study the evolution of the bar fraction in disc galaxies between using multi-band coloured images from JWST CEERS. These images were classified by citizen scient…
Origin of the two-armed vertical phase-spiral in the inner Galactic disk
Rimpei Chiba, Neige Frankel, Chris Hamilton
Gaia recently revealed a two-armed spiral pattern in the vertical phase-space distribution of the inner Galactic disk (guiding radius kpc), indicating that…
