The H specific angular momentum of dwarf galaxies
Simon Deeley, Sarah Sweet, Dilyar Barat +3
The relationship between a galaxy's specific angular momentum and its mass , parameterised by and known as the Fall relation, has emerged as a fundamental sc…
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…
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…
Spin-filament alignments to unravel galaxy evolution and model intrinsic alignments
Stefania Barsanti, Clotilde Laigle, Nicolas Bouché +7
By the 2040s, several all-sky surveys will have transformed our view of the large-scale structure. However, one of the major outstanding questions in astrophysics will remain: unde…
