Early onset of the hot circumgalactic medium around Milky Way galaxies
Víctor Rufo-Pastor, Oscar Agertz, Santi Roca-Fábrega +6
Hot coronae are key regulators in Milky Way (MW)-type galaxy formation and are thought to emerge once a galaxy's dark matter halo crosses a critical mass threshold, $M_{\mathrm{vir…
The driving mode of turbulence in disc galaxy simulations with adaptive mesh refinement
James Watt, Christoph Federrath, Thorsten Tepper-Garcia +2
Turbulence is a key ingredient in controlling the structure of the interstellar medium (ISM) and star formation, yet we still lack a detailed understanding of its drivers in galaxi…
Nexus-CDM: Isolated Galaxy Simulations with Cosmologically Evolving Dark-Matter Halos I. Method and Validation
Thor Tepper-García, Joss Bland-Hawthorn, Oscar Agertz +1
Galaxy evolution can be modelled in two complementary ways. Standalone simulations place a single galaxy in isolation, evolving it under controlled initial conditions without the s…
Turbulent gas-rich discs at high redshift: the origin of early massive stellar bars

Recent observations combining the power of ALMA and JWST have revealed large ( kpc), massive () stellar bars at when the Universe…
Validating full-spectrum fitting with a synthetic integral-field spectroscopic observation of the Milky Way
Zixian Wang, Michael R. Hayden, Sanjib Sharma +5
Ongoing deep IFS observations of disk galaxies provide opportunities for comparison with the Milky Way (MW) to understand galaxy evolution. However, such comparisons are marred by…
Detecting a disk bending wave in a barred-spiral galaxy at redshift 4.4
Takafumi Tsukui, Emily Wisnioski, Joss Bland-Hawthorn +4
The recent discovery of barred spiral galaxies in the early universe () poses questions of how these structures form and how they influence galaxy evolution in the early unive…
Beyond BPT: A New Multi-Dimensional Diagnostic Diagram for Classifying Power Sources Tested Using the SAMI Galaxy Survey
Victor Johnston, Anne Medling, Brent Groves +11
Current methods of identifying the ionizing source of nebular emission in galaxies are well defined for the era of single fiber spectroscopy, but still struggle to differentiate th…
GAMA/DEVILS: Cosmic star formation and AGN activity over 12.5 billion years
Jordan C. J. D'Silva, Simon P. Driver, Claudia D. P. Lagos +11
We use the Galaxy and Mass Assembly (GAMA) and the Deep Extragalactic Visible Legacy Survey (DEVILS) observational data sets to calculate the cosmic star formation rate (SFR) and a…
The MAGPI Survey: Impact of environment on the total internal mass distribution of galaxies in the last 5 Gyr
Caro Derkenne, Richard M. McDermid, Adriano Poci +20
We investigate the impact of environment on the internal mass distribution of galaxies using the Middle Ages Galaxy Properties with Integral field spectroscopy (MAGPI) survey. We u…
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…
The GALAH survey: New diffuse interstellar bands found in residuals of 872,000 stellar spectra
Rok Vogrinčič, Janez Kos, Tomaž Zwitter +11
We use more than 872,000 mid-to-high resolution (R 20,000) spectra of stars from the GALAH survey to discern the spectra of diffuse interstellar bands (DIBs). We use four wi…
The SAMI-Fornax Dwarfs Survey III: Evolution of [/Fe] in dwarfs, from Galaxy Clusters to the Local Group
J. Romero-Gómez, Reynier F. Peletier, J. A. L. Aguerri +10
Using very deep, high spectral resolution data from the SAMI Integral Field Spectrograph we study the stellar population properties of a sample of dwarf galaxies in the Fornax Clus…
The rapid onset of stellar bars in the baryon-dominated centers of disk galaxies
J. Bland-Hawthorn, T. Tepper-Garcia, O. Agertz +1
Recent observations of high-redshift galactic disks () show a strong negative trend in the dark matter fraction with increasing baryonic surface density. For…
Evolution in the orbital structure of quiescent galaxies from MAGPI, LEGA-C and SAMI surveys: direct evidence for merger-driven growth over the last 7 Gy
Francesco D'Eugenio, Arjen van der Wel, Joanna M. Piotrowska +37
We present the first study of spatially integrated higher-order stellar kinematics over cosmic time. We use deep rest-frame optical spectroscopy of quiescent galaxies at redshifts…
The SAMI Galaxy Survey: Environmental analysis of the orbital structures of passive galaxies
Giulia Santucci, Sarah Brough, Jesse van de Sande +11
Most dynamical models of galaxies to date assume axisymmetry, which is not representative of a significant fraction of massive galaxies. We have built triaxial orbit-superposition…
Different higher-order kinematics between star-forming and quiescent galaxies based on the SAMI, MAGPI and LEGA-C surveys
