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…
SPARCS -- combining radiation hydrodynamics with non-equilibrium metal chemistry in the SWIFT astrophysical code
Tsang Keung Chan, Alexander J. Richings, Tom Theuns +3
We present SPARCS, which combines the moment-based radiative transfer method SPH-M1RT with the non-equilibrium metal chemistry solver CHIMES in the modern highly-parallel astrophys…
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…
KURVS: chemical properties from multiple strong line calibrations for star-forming galaxies at
Zefeng Li, UgnÄ DudzeviÄiÅ«tÄ, 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…
Scatter in the star formation rate-halo mass relation: secondary bias and its impact on line-intensity mapping
Rui Lan Jun, Tom Theuns, Kana Moriwaki +1
We use the IllustrisTNG cosmological hydrodynamical simulations to study the impact of secondary bias -- specifically, the correlation between star formation rate (SFR) and halo bi…
