Metallicity Gradients in Modern Cosmological Simulations. I. Tension between Smooth Stellar Feedback Models and Observations

The Astrophysical Journal
The metallicity of galaxies, and its variation with galactocentric radius, provides key insights into the formation histories of galaxies and the physical processes driving their evolution.

Contribution of AGN to the Morphological Parameters of Their Host Galaxies up to Intermediate Redshifts of z ∼ 2

Galaxies
The presence of Active Galaxy Nuclei (AGN) can affect the morphological classification of galaxies. This work aims to determine how the contribution of AGN affects the most-used morphological parameters down to the redshift of z ∼ 2 in COSMOS-like ...

Halo mass functions at high redshift

The Open Journal of Astrophysics
Recent JWST observations of very early galaxies, at $z \geq 10$, has led to claims that tension exists between the sizes and luminosities of high-redshift galaxies and what is predicted by standard ${\Lambda}$CMD models.

The Average Stellar Population Age and Metallicity of Intermediate-redshift Quiescent Galaxies

The Astrophysical Journal
The HectoMAP spectroscopic survey provides a unique mass-limited sample of more than 35,000 quiescent galaxies ( D _n 4000 > 1.5) covering the redshift range 0.2  10 ^11 M _⊙ ) assemble the bulk of their stars at earlier epochs.
