The ALPINE-CRISTAL-JWST Survey: Investigating the role of interstellar dust, gas and stars in high-z galaxies at kpc-scales

F. Lopez, M. Relano, I. De Looze +37

A comprehensive understanding of galaxy evolution requires a detailed analysis of gas and dust, their distribution, and evolution within galaxies. We analyse spatially resolved (~k…

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…

The Qz5 Survey (II): Metallicity Evolution of Damped Lyα Systems Out to z5

Marie Wisz, Marc Rafelski, Grecco Oyarzun +10

Damped Ly absorbers (DLAs) are the highest \HI\ column density (\NHI) absorption line systems detected in the spectra of background quasars. DLAs dominate the neutral gas conten…

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…

The Environments of Fast Radio Bursts Viewed Using Adaptive Optics

Michele N. Woodland, Alexandra G. Mannings, J. Xavier Prochaska +10

We present GeMS/GSAOI observations of five fast radio burst (FRB) host galaxies with sub-arcsecond localizations. We examine and quantify their spatial distributions and locations…
