Systematically Asymmetric: A comparison of \hi\ profile asymmetries in real and simulated galaxies
N. Deg, S. Blyth, N. Hank +2
We examine different measures of asymmetry for galaxy HI velocity profiles. We introduce the channel-by-channel asymmetry and the velocity-of-equality statistics to quantify profil…

Measuring Galaxy Asymmetries in 3D
N. Deg, M. Perron-Cormier, K. Spekkens +3
One of the commonly used non-parametric morphometric statistics for galaxy profiles and images is the asymmetry statistic. With an eye to current and upcoming large neutral hydroge…

ASymba: HI global profile asymmetries in the Simba simulation
M. Glowacki, N. Deg, S. L. Blyth +4
Asymmetry in the spatially integrated, 1D HI global profiles of galaxies can inform us on both internal (e.g. outflows) and external (e.g. mergers, tidal interactions, ram pressure…
