Chemical Evolution of Bulges of Active Galactic Nuclei in the Early Universe: Roles of Accreting Stars

The Astrophysical Journal
JWST/NIRCam observations reveal dense stellar cores in high-redshift galactic bulges, indicative of sustained star formation and potential stellar accretion.

A 13 Billion Year View of Galaxy Growth: Metallicity Gradient Evolution from the Local Universe to z = 9 with JWST and Archival Surveys

The Astrophysical Journal Supplement Series
Galaxy gas-phase metallicity gradients have been extensively studied over the past four decades, both in the local and in the high-redshift Universe, as they trace the baryon cycle and growth of galaxies.

On the Significance of the Thick Disks of Disk Galaxies

The Astrophysical Journal Supplement Series
Thick disks are a prevalent feature observed in numerous disk galaxies, including our own Milky Way. Their significance has been reported to vary widely, ranging from a few percent to 100% of the disk mass, depending on the galaxy and the measurement ...

Local variations of the radial metallicity gradient in a simulated NIHAO-UHD Milky Way analogue and their implications for (extra-)galactic studies

The Open Journal of Astrophysics
Radial metallicity gradients are fundamental to understanding galaxy formation and evolution. In our high-resolution simulation of a NIHAO-UHD Milky Way analogue, we analyze the linearity, scatter, spatial coherence, and age-related variations of ...
