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

open access: yesGalaxies
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

open access: yesThe 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

open access: yesThe 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.
