Galactic seismology: can the Gaia 'phase spiral' co-exist with a clumpy, turbulent interstellar medium?

Thor Tepper-García, Joss Bland-Hawthorn, Timothy R. Bedding +2

The Gaia satellite revealed a remarkable spiral pattern ('phase spiral', PS) in the z-Vz phase-plane throughout the solar neighbourhood, where z and Vz are the displacement and vel…

Turbulent gas-rich discs at high redshift: origin of thick stellar discs through 3D 'baryon sloshing'

Joss Bland-Hawthorn, Thor Tepper-Garcia, Oscar Agertz +8

In response to recent observations from JWST and ALMA, we explore a new class of dynamically self-consistent models using our AGAMA/Ramses hydrodynamic N-body framework (Nexus) tha…

The far side of the Galactic bar/bulge revealed through semi-regular variables

Daniel R. Hey, Daniel Huber, Benjamin J. Shappee +8

The Galactic bulge and bar are critical to our understanding of the Milky Way. However, due to the lack of reliable stellar distances, the structure and kinematics of the bulge/bar…

SPYGLASS. III. The Fornax-Horologium Association and its Traceback History within the Austral Complex

Ronan Kerr, Adam L. Kraus, Simon J. Murphy +3

The study of young associations is essential for building a complete record of local star formation processes. The Fornax-Horologium association (FH), including the Fornacis…

Age dating of an early Milky Way merger via asteroseismology of the naked-eye star Indi

William J. Chaplin, Aldo M. Serenelli, Andrea Miglio +81

Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies. While these accreted stellar populations can be forensically identified as kinematic…

The K2-HERMES Survey: Age and Metallicity of the Thick Disc

Sanjib Sharma, Dennis Stello, Joss Bland-Hawthorn +34

Asteroseismology is a promising tool to study Galactic structure and evolution because it can probe the ages of stars. Earlier attempts comparing seismic data from the {\it Kepler}…
