WALLABY pilot survey: The diversity of HI structural parameters in nearby galaxies
Abstract We investigate the diversity in the sizes and average surface densities of the neutral atomic hydrogen (H i ) gas discs in $\sim$ 280 nearby galaxies detected by the Widefield ASKAP L-band Legacy All-sky Blind Survey (WALLABY). We combine the uniformly observed, interferometric H i data from pilot observations …
