JADES Imaging of GN-z11: Revealing the Morphology and Environment of a Luminous Galaxy 430 Myr after the Big Bang

The Astrophysical Journal, 2023
We present JWST NIRCam nine-band near-infrared imaging of the luminous z = 10.6 galaxy GN-z11 from the JWST Advanced Deep Extragalactic Survey of the GOODS-N field.

Disk Galaxy Formation in a LambdaCDM Universe

, 2004
We describe hydrodynamical simulations of galaxy formation in a Lambda cold dark matter (CDM) cosmology performed using a subresolution model for star formation and feedback in a multiphase interstellar medium (ISM).

A fundamental test for stellar feedback recipes in galaxy simulations [PDF]

, 2019
Direct comparisons between galaxy simulations and observations that both reach scales < 100 pc are strong tools to investigate the cloud-scale physics of star formation and feedback in nearby galaxies.

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

The 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.

Collision‐induced Galaxy Formation

The Astrophysical Journal, 1998
We present a semi-analytical model in which galaxy collisions and strong tidal interactions, both in the field and during the collapse phase of groups and clusters help determine galaxy morphology. From a semi-analytical analysis based on simulation results of tidal collisions (Aguilar & White 1985), we propose simple rules for energy exchanges ...

Multiwavelength Study of Massive Galaxies at z~2. I. Star Formation and Galaxy Growth [PDF]

, 2007
Examining a sample of massive galaxies at 1.4 < z < 2.5 with KVega < 22 from GOODS, we compare photometry from Spitzer at mid- and far-IR to submillimeter, radio, and rest-frame UV wavelengths, to test the agreement between different tracers of star ...

The star-formation history of the Milky Way Galaxy

, 2009
The star-formation histories of the main stellar components of the Milky Way constrain critical aspects of galaxy formation and evolution. I discuss recent determinations of such histories, together with their interpretation in terms of theories of disk ...

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

The 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 ...
