Our current understanding of galaxy evolution still has many uncertainties associated with the details of the accretion, processing, and removal of gas across cosmic time. The next generation of radio telescopes will image the neutral hydrogen (H i) in galaxies over large volumes at high redshifts, which will provide key insights into these processes. We are conducting the COSMOS H i Large Extragalactic Survey (CHILES) with the Karl G. Jansky Very Large Array, which is the first survey to…

CHILES VI: H i and H α observations for z < 0.1 galaxies; probing H i spin alignment with filaments in the cosmic web
We present neutral hydrogen (H i) and ionized hydrogen (H α) observations of 10 galaxies out to a redshift of 0.1. The H i observations are from the first epoch (178 h) of the COSMOS H i Large
Atomic Hydrogen in Star-forming Galaxies at Intermediate Redshifts
We have used the upgraded Giant Metrewave Radio Telescope to carry out a deep (117 on-source hours) L-band observation of the Extended Groth Strip, to measure the average neutral hydrogen (H i) mass
H I 21-centimetre emission from an ensemble of galaxies at an average redshift of one.
TLDR
It is found that the H I mass can fuel the observed star-formation rates for only 1 to 2 billion years in the absence of fresh gas infall, which suggests that gas accretion onto galaxies at redshifts of less than one may have been insufficient to sustain high star- formation rates in star-forming galaxies.
Disc galaxy resolved in H I absorption against the radio lobe of 3C 433: Case study for future surveys
The neutral atomic gas content of galaxies is usually studied in the H I 21 cm emission line of hydrogen. However, as we go to higher redshifts, owing to the weak strength of the transition, we need

Determining the spatial distribution and intrinsic physical properties of neutral hydrogen on cosmological scales is one of the key goals of next-generation radio surveys. We use the EAGLE galaxy
H i 21-cm absorption survey of quasar-galaxy pairs: Distribution of cold gas around z < 0.4 galaxies
We present the results from our survey of HI 21-cm absorption, using GMRT, VLA and WSRT, in a sample of 55 z<0.4 galaxies towards radio sources with impact parameters (b) in the range ~0-35 kpc. In
A study of the H I gas fractions of galaxies at z ∼ 1
