MIGHTEE-HI: The direct detection of neutral hydrogen in galaxies at
Matt J. Jarvis, Madalina N. Tudorache, I. Heywood +18
Atomic hydrogen constitutes the gas reservoir from which molecular gas and star formation in galaxies emerges. However, the weakness of the line means it has been difficult to dire…
