The Heavy Metal Survey: Star Formation Constraints and Dynamical Masses of 21 Massive Quiescent Galaxies at z = 1.3–2.3

open access: yesThe Astrophysical Journal
In this paper, we present the Heavy Metal Survey, which obtained ultradeep medium-resolution spectra of 21 massive quiescent galaxies at 1.3 < z < 2.3 with Keck/LRIS and MOSFIRE.

Star Formation Rates, Metallicities, and Stellar Masses on Kiloparsec Scales in TNG50

open access: yesThe Astrophysical Journal
Integral field units have extended our knowledge of galactic properties to kiloparsec (or, sometimes, even smaller) patches of galaxies. These scales are where the physics driving galaxy evolution (feedback, chemical enrichment, etc.) take place ...

The parameter space of galaxy formation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2010
Semi-analytic models are a powerful tool for studying the formation of galaxies. However, these models inevitably involve a significant number of poorly constrained parameters that must be adjusted to provide an acceptable match to the observed universe. In this paper, we set out to quantify the degree to which observational data-sets can constrain the

A Full Active Galactic Nuclei Feedback Prescription for Numerical Models: Negative, Positive, and Hot Gas-ejection Modes

open access: yesThe Astrophysical Journal Supplement Series
We build upon the state-of-the-art semianalytic model FEGA24 for the formation and evolution of galaxies, which integrates the latest prescriptions relevant to galaxy formation and evolution, alongside a comprehensive active galactic nuclei (AGN ...

Observational Evidence for an Age Dependence of Halo Bias

open access: yes, 2006
We study the dependence of the cross-correlation between galaxies and galaxy groups on group properties. Confirming previous results, we find that the correlation strength is stronger for more massive groups, in good agreement with the expected mass ...

Formation Models of Galaxies [PDF]

open access: yesAstrophysics and Space Science, 1995
Unfortunately Dr. White was not able to finish a written version of his presentation at the Symposium in time for inclusion in these proceedings. He refers the interested readers to his lecture notes at the August 1993 Les Houches summer school (White, 1995).

Galaxy Quenching at the High Redshift Frontier: A Fundamental Test of Cosmological Models in the Early Universe with JWST-CEERS

open access: yesThe Astrophysical Journal
We present an analysis of the quenching of star formation in massive galaxies ( M _* > 10 ^9.5 M _⊙ ) within the first 0.5–3 Gyr of the Universe’s history utilizing JWST-CEERS data.

And the winner is: galaxy mass

open access: yes, 2011
The environment is known to affect the formation and evolution of galaxies considerably best visible through the well-known morphology-density relationship.
