Forged in Quenching: Morphological Transformation across Star-forming and Quiescent Galaxies in EAGLE
Kai Wang, Carlton Baugh, Sownak Bose +15
The connection between morphology and quenching in central galaxies is well established, but its physical origin remains widely debated. We address this by tracing the main progeni…
Ruffled Feathers: Merger-driven galaxy size growth and structural transformation in EAGLE
Kai Wang, Carlton Baugh, Sownak Bose +9
Galaxy mergers drive both the size growth and the transformation from discs to spheroids, yet the prescriptions used to model these processes in semi-analytic frameworks have not b…
Inflow-driven galaxy evolution - I. Revealing the physics of the fundamental metallicity relation
Kai Wang, Carlton Baugh, N. F. Boardman +11
We present a unified physical framework for the fundamental metallicity relation (FMR), based on the mass-continuity equations. The FMR is not merely the anti-correlation between s…
KURVS: chemical properties from multiple strong line calibrations for star-forming galaxies at
Zefeng Li, Ugnė Dudzevičiūtė, Annagrazia Puglisi +13
Gas-phase oxygen abundance (metallicity) properties can be constrained through emission line analyses, and are of great importance to investigate galaxy evolution histories. We pre…
Emission line tracers of galactic outflows driven by stellar feedback in simulations of isolated disk galaxies
Elliot L. Howatson, Alexander J. Richings, Elke Roediger +7
Hydrodynamic simulations can connect outflow observables to the physical conditions of outflowing gas. Here, we use simulations of isolated disk galaxies ranging from dwarf mass ($…
The HyLight model for hydrogen emission lines in simulated nebulae
Yuankang Liu, Tom Theuns, Tsang Keung Chan +2
Hydrogen recombination lines provide key diagnostics of ionized gas in galaxies, yet most hydrodynamical simulations estimate hydrogen level populations using interpolated emissivi…
