Not so-dark: High resolution HI imaging of J0139+4328 and identification of an optical counterpart

Barbara Å iljeg, Elizabeth A. K. Adams, Tom A. Oosterloo +4

Dark galaxies - systems rich in neutral hydrogen (HI) gas but with no stars - are a common prediction of numerous theoretical models and cosmological simulations. However, the uneq…

CHILES XI: Resolved HI morphologies and the evolution of the H2/HI ratio over the last five billion years

J. Blue Bird, N. Luber, H. B. Gim +8

We present the neutral gas morphology of four galaxies from z = 0.22 to 0.47 obtained with the COSMOS HI Large Extragalactic Survey (CHILES). The HI is resolved at the highest reds…

The CHILES Continuum & Polarization Survey-II: Radio Continuum Source Catalog and Radio Properties

Hansung B. Gim, Min S. Yun, Nicholas M. Luber +5

The COSMOS HI Large Extragalactic Survey (CHILES) Continuum & Polarization (CHILES Con Pol) survey is an ultra-deep continuum imaging study of the COSMOS field conducted using the…

CHILES IX: Observational and Simulated HI Content and Star Formation of Blue Galaxies in Different Cosmic Web Environments

Nicholas Luber, Farhanul Hasan, J. H. van Gorkom +15

We examine the redshift evolution of the relationship between the neutral atomic hydrogen ({\HI}) content and star-formation properties of blue galaxies, along with their location…

CHILES VIII: Probing Evolution of Average HI Content in Star Forming Galaxies over the Past 5 Billion Years

Nicholas Luber, D. J. Pisano, J. H. van Gorkom +9

Utilizing the COSMOS HI Large Extragalactic Survey (CHILES) dataset, we investigate the evolution of the average atomic neutral hydrogen (HI) properties of galaxies over the contin…

New constraints on the evolution of the MHI-M* scaling relation combining CHILES and MIGHTEE-HI data

Alessandro Bianchetti, Francesco Sinigaglia, Giulia Rodighiero +23

The improved sensitivity of interferometric facilities to the 21-cm line of atomic hydrogen (HI) enables studies of its properties in galaxies beyond the local Universe. In this wo…
