The KAGG survey: KCWI Analysis of Gas around Galaxies at z~3-5

Grecco A. Oyarzún, Marc Rafelski, J. Xavier Prochaska +5

We present the KCWI Analysis of Gas around Galaxies (KAGG) survey of Ly emission around Damped Ly Absorbers (DLAs) at z~3-5 with the Keck Cosmic Web Imager (KCWI) integral-fi…

Impact of Cosmic Filaments on Galaxy Morphological Evolution and Predictions of Early Cosmic Web Structure for Roman

Farhanul Hasan, Haowen Zhang, Viraj Pandya +10

We leverage the IllustrisTNG cosmological simulations to test how the large-scale cosmic web shapes galaxy morphology and to forecast the early cosmic web structure that the Nancy…

The Qz5 Survey (I): How the HI Mass Density of the Universe Evolves With Cosmic Time

Grecco A. Oyarzún, Marc Rafelski, Lise Christensen +9

We report that the neutral hydrogen (HI) mass density of the Universe () increases with cosmic time since , peaks at , and then decreases toward $z \sim…

Galaxy assembly bias in the stellar-to-halo mass relation for red central galaxies from SDSS

Grecco A. Oyarzún, Jeremy L. Tinker, Kevin Bundy +2

We report evidence of galaxy assembly bias - the correlation between galaxy properties and biased secondary halo properties at fixed halo mass (M) - in the stellar-to-halo mass…

UVCANDELS: The role of dust on the stellar mass-size relation of disk galaxies at 0.5 3.0

Kalina V. Nedkova, Marc Rafelski, Harry I. Teplitz +30

We use the Ultraviolet Imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey fields (UVCANDELS) to measure half-light radii in the rest-frame far-UV for $\s…

The Contribution of In-situ and Ex-situ Star Formation in Early-Type Galaxies: MaNGA versus IllustrisTNG

Carlo Cannarozzo, Alexie Leauthaud, Grecco A. Oyarzún +6

We compare stellar mass surface density, metallicity, age, and line-of-sight velocity dispersion profiles in massive () present-day early-type g…
