H I galaxy morphometricsGalaxy morphology in atomic hydrogen (H I) and in the ultraviolet (UV) are closely linked. This has motivated their combined use to quantify morphology over the full H I disc for both H I and UV imaging. We apply galaxy morphometrics: concentration, asymmetry, gini, M20 and multimode-intensity-deviation statistics to the first moment-0 maps of the WALLABY Survey of galaxies in the hydra cluster centre. Taking advantage of this new H I survey, we apply the same morphometrics over the full H I extent on archival GALEX FUV and NUV data to explore how well H I truncated, extended ultraviolet disc (XUV) and other morphological phenomena can be captured using pipeline WALLABY data products. Extended H I and UV discs can be identified relatively straightforward from their respective concentration. Combined with WALLABY H I, even the shallowest GALEX data are sufficient to identify XUV discs. Our second goal is to isolate galaxies undergoing ram-pressure stripping in the H I morphometric space. We employ four different machine learning techniques, a decision tree, a k-nearest neighbour, a support-vector machine, and a random forest. Up to 80 per cent precision and recall are possible with the random forest giving the most robust results.galaxy-clustersgalaxy-groupsgalaxiesintergalactic-mediumvisible-astronomynarrow-band-photometryh-i-line-emissiongalaxy-classification-systemsastrometrygalaxy-kinematicsgalaxy-radiigalactic-and-extragalactic-astronomyinterstellar-mediumobservational-astronomyhttps://dc.g-vo.org/rr/q/lp/custom/CDS.VizieR/J/MNRAS/521/1502https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/521/15022023MNRAS.521.1502Hhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/521/1502Cone search capability for table J/MNRAS/521/1502/table (Astrometric informations and morphometric parameters of our HI WALLABY galaxies)Holwerda B.W.Bigiel F.Bosma A.Courtois H.M.Deg N.Denes H.,Elagali A.For B.-Q.Koribalski B.Leahy D.A.Lee-Waddell K.,Lopez-Sanchez A.R.Oh S.-H.Reynolds T.N.Rhee J.Spekkens K.Wang J.,Westmeier T.Wong O.I.CDS2026https://cds.unistra.fr/vizier-org/licences_vizier.htmlCDS support team <cds-question@unistra.fr>DatasetAstroObjectsastronomy
