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_*-Ï_e) and extend it to thin and thick subcomponents using orbit-based dynamical models of 161 SA…
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…
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…
Large-scale and local environmental drivers of quenching: tracing H concentration in X-ray and optical galaxy groups
Stefania Barsanti, Di Wang, Matthew Colless +11
To explore the environmental mechanisms causing quenching in nearby star-forming galaxies, we study the variation with local and large-scale environments of a star formation concen…
Hector Galaxy Survey: Data Processing, Quality Control and Early Science
S. Oh, M. L. P. Gunawardhana, S. M. Croom +52
The Hector Galaxy Survey is a new optical integral field spectroscopy (IFS) survey currently using the AAT to observe up to 15,000 galaxies at low redshift (). The Hector…
