The cold interstellar medium (ISM) plays a central role in the galaxy evolution process. It is
the reservoir that fuels galaxy growth via star formation, the repository of material formed by …

The redshifted 21 cm line is an emerging tool in cosmology, in principle permitting three-
dimensional surveys of our universe that reach unprecedentedly large volumes, previously …

One of the key open questions in extragalactic astronomy is what stops star formation in
galaxies. While it is clear that the cold gas reservoir, which fuels the formation of new stars …

Context. Measurement of the Galactic neutral atomic hydrogen (H i) column density, NH i,
and brightness temperatures, TB, is of high scientific value for a broad range of astrophysical …

Gravitational waves have been detected from a binary neutron star merger event,
GW170817. The detection of electromagnetic radiation from the same source has shown …

We present the catalog of∼ 31,500 extragalactic H i line sources detected by the completed
Arecibo Legacy Fast ALFA (ALFALFA) survey out to z< 0.06, including both high signal-to …

Abstract The Widefield ASKAP L-band Legacy All-sky Blind surveY (wallaby) is a next-
generation survey of neutral hydrogen (H i) in the Local Universe. It uses the widefield, high …

We present the extended GALEX Arecibo SDSS Survey (xGASS), a gas fraction-limited
census of the atomic hydrogen (H i) gas content of 1179 galaxies selected only by stellar …

We present the data and initial results from the first pilot survey of the Evolutionary Map of
the Universe (EMU), observed at 944 MHz with the Australian Square Kilometre Array …
