Turbulent gas-rich discs at high redshift: the origin of early massive stellar bars
Joss Bland-Hawthorn, Thor Tepper-Garcia, Chris Hamilton +4
Recent observations combining the power of ALMA and JWST have revealed large ( kpc), massive () stellar bars at when the Universe…
The GALAH Survey: Neutron-Capture Elemental Abundances for 350,000 Gaia-RVS spectra and the Chemodynamics of Accreted Structures
Pradosh Barun Das, Daniel B. Zucker, Aldo Mura-Guzmán +15
We present a comprehensive data-driven spectroscopic analysis of 357,415 red giant stars using Gaia DR3 Radial Velocity Spectrometer (RVS) spectra (8460-8700 A; ),…
AMPM I. A Targeted Search for Asteroid Mass Primordial Black Hole Microlenses
Renee Key, Edward N. Taylor, Ken C. Freeman +5
Gravitational microlensing is a powerful technique for constraining the abundance of dark matter in asteroid mass to supermassive primordial black holes at masses of $-11 \lesssim…
Bar Properties and Star-by-Star Bar Membership via Action Conservation
Elizabeth J. Iles, Finn A. Pal, Joss Bland-Hawthorn +1
A bar-like central feature is commonly observed in both nearby and distant spiral-type galaxies, including the Milky Way. While many methods exist to categorise this morphology, no…
The GALAH survey: Improving chemical abundances using star clusters
Janez Kos, Sven Buder, Kevin L. Beeson +18
Large spectroscopic surveys aim to consistently compute stellar parameters of very diverse stars while minimizing systematic errors. We explore the use of stellar clusters as bench…
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…
