I review recent results from galaxy simulations that particularly focus on the epoch of reionization. In this talk, I pay special attention to the transition from metal-free Population III stars to the formation of the first galaxies and what type of chemical imprint they might have on these small galaxies. We have investigated the variations in galaxy properties when changing various...

H-ingestion events in low metallicity and Pop III stars have been reported previously, but have not yet been investigated in any detail. In order to explain the most iron-poor star found to date, the Keller star (SMSS J031300.362670839.3), we propose a scenario based on stellar evolution simulations in which a 45Msun Pop III star experiences H-ingestion into the convective He-shell burning...

I will present new results of our numerical simulations of i-process nucleosynthesis
on both single white dwarfs and rapidly accreting white dwarfs in close binary systems.
The i process occurs when convection driven by a He-shell flash ingests H from its
surrounding H-rich layer. Contrary to the case of H-ingestion in single stars (such
as the post-AGB star Sakurai's object or low-Z AGB...

HECTOR is a NaI(Tl) segmented total absorption spectrometer at the University of Notre Dame for measurements of proton and alpha capture reactions relevant for p-process nucleosynthesis. In this talk the commissioning of HECTOR using standard gamma-ray sources and known resonances in 27Al(p,g)28Si reaction will be presented. As a proof-of-principle, the cross section measurements of...

Talk [Main Conference]
Galactic chemical evolution (GCE) is a multidisciplinary topic that involves nuclear physics, stellar evolution, galaxy evolution, and cosmology. Observations, experiments, and theories need to work together in order to build a comprehensive understanding of how the chemical elements synthesized in astronomical events are spread inside and around galaxies and recycled into new generations of...
