Hector Galaxy Survey: Falling in Between - Infalling Galaxies in the Midst of the Abell 3667 Merger
Oğuzhan Çakır, Matt Owers, Gabriella Quattropani +38
Whether cluster mergers enhance ram pressure stripping (RPS) and accelerate member galaxy evolution remains an open question. Here, we investigate galaxy populations in the nearby…
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…
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…
findAbar: how astronomers may perceive the bar in galaxies differently
Elizabeth J. Iles, Joss Bland-Hawthorn, Courtney Crawford +18
Bars are ubiquitous morphological features in the observed distribution of galaxies. There are similarly many methods for classifying these features and, without a strict theoretic…
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…
JADES NIRSpec Spectroscopy of GN-z11: Evidence for Wolf-Rayet contribution to stellar populations at 430 Myr after Big Bang?
Madusha L. P. Gunawardhana, Jarle Brinchmann, Scott Croom +3
We investigate the unusual emission line luminosity ratios observed in the JADES NIRSpec spectroscopy of GN-z11, which reveal exceptionally strong emission lines and a significant…
