The evolution of galaxies from cosmic noon to the present day provides a key window to probe the balance between early, rapid bulge formation and prolonged disk growth. The epoch a…
Kinematic scaling of thin and thick discs from SAMI to NewHorizon
Sree Oh, J. K. Jang, Giulia Santucci +8
We revisit the relation between disc stellar mass and disc velocity dispersion (M_*-σ_e) and extend it to thin and thick subcomponents using orbit-based dynamical models of 161 SAM…
Morphology-spin connection in the SAMI Galaxy Survey
Youngmin Baek, Sree Oh, Sukyoung K. Yi +5
The spin parameter is a proxy for the specific stellar angular momentum of galaxies and is a useful metric for classifying kinematic morphology. This study aims to q…
The MAGPI Survey: Evidence for Non-Universal Resolved Dust Attenuation Relations Beyond the Local Universe
A. Mailvaganam, T. Zafar, P. Corcho-Caballero +39
We study the spatially resolved relation between dust attenuation () and star formation rate surface density () in galaxies from the MAGPI survey ($0.25 < z…
Hector Galaxy Survey: Optical IFU and Chandra Reveal a Low-Luminosity AGN Behind Extended LINER Emission
Kyuseok Oh, Gabriella Quattropani, Pratyush Kumar Das +25
We present evidence that the Hector Galaxy Survey galaxy C901005481609968 (), which exhibits spatially extended LINER-like emission in optical integral-field spe…
Hector Galaxy Survey: Linking the low- and high-mass ends of the initial mass function in star-forming galaxies
Diego Salvador, Andrew Hopkins, Matt Owers +30
The stellar initial mass function (IMF) is a fundamental ingredient in galaxy evolution, linking observed integrated light to galaxy properties. Constraining the full IMF shape bey…
The GECKOS survey: Resolving the molecular and ionised gas in the galactic outflow of ESO~484-036
J. Hernández-Yévenes, D. B. Fisher, B. Mazzilli Ciraulo +20
We present a spatially resolved, multiphase study of the outflow in the edge-on starburst galaxy ESO~484-036 from the GECKOS survey, combining VLT/MUSE H and ALMA CO(10) obse…
Measuring the evolution of stellar bars with the host galaxy's spin
Robin Joshi, Scott M. Croom, Stefania Barsanti +3
We examine to what extent the galaxy spin parameter proxy () is affected by bar formation and how it is related to the strong and weak classifications of stellar bars. By crea…
EMU/GAMA: A statistical perspective on active galactic nuclei diagnostics
J. Prathap, A. M. Hopkins, R. Carvajal +19
While it is well known that galaxies are composites of many emission processes, quantifying the various contributions remains challenging. In this work, we use unsupervised machine…
The SAMI Galaxy Survey: Quenching of Star Formation in Clusters III. Ram-Pressure-Affected Galaxy Populations
Oğuzhan Çakır, Matt S. Owers, Luca Cortese +15
Cluster environments influence galaxy evolution by curtailing star formation activity, notably through ram-pressure stripping (RPS). In this study, using spatially resolved spectro…
Large-scale and local environmental drivers of quenching: tracing H concentration in X-ray and optical galaxy groups
