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…
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: 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…
Cosmic web stripping and starvation of low-mass filament galaxies in TNG50
Daria Zakharova, Gabriella De Lucia, Benedetta Vulcani +3
Galaxy properties are known to correlate with their location within the cosmic web. However, the role of filaments remains poorly understood, particularly for low-mass galaxies, wh…
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 cre…
