Simba-c : An updated chemical enrichment model for galactic chemical evolution in the SIMBA simulation
(2023-10-30)
We introduce a new chemical enrichment and stellar feedback model into GIZMO, using the SIMBA sub-grid models as a base. Based on the state-of-the-art chemical evolution model of Kobayashi et al., SIMBA-C tracks 34 elements ...
Astraeus V: the emergence and evolution of metallicity scaling relations during the epoch of reionization
(2023-01-30)
In this work, we have implemented a detailed physical model of galaxy chemical enrichment into the ASTRAEUS (seminumerical rAdiative tranSfer coupling of galaxy formaTion and Reionization in N-body dark matter simUlationS) ...
The KLEVER survey: nitrogen abundances at z ∼ 2 and probing the existence of a fundamental nitrogen relation
(2022-05-30)
We present a comparison of the nitrogen-to-oxygen ratio (N/O) in 37 high-redshift galaxies at z ∼2 taken from the KMOS Lensed Emission Lines and VElocity Review (KLEVER) Survey with a comparison sample of local galaxies, ...
Galactic 26Al traces metal loss through hot chimneys
(2021-02-01)
Radioactive 26Al is an excellent tracer for metal ejection in the Milky Way, and can provide a direct constraint on the modelling of supernova feedback in galaxy evolution. Gamma-ray observations of the 26Al decay line ...
Galactic Simulations of r-process Elemental Abundances
(2019-03-01)
We present the distributions of elemental abundance ratios using chemodynamical simulations that include four different neutron capture processes: magnetorotational supernovae, neutron star mergers, neutrino-driven winds, ...
