FEASTS and MHONGOOSE: HI Column Density Distribution at for
Jing Wang, Xuchen Lin, Ze-Zhong Liang +24
We present the first HI column density distribution function, , extending down to . This was derived from high-s…
MeerKAT view of Hickson Compact Groups: II. HI deficiency in the core and surrounding regions
A. Sorgho, L. Verdes-Montenegro, R. Ianjamasimanana +25
Hickson compact groups (HCGs) offer an ideal environment for investigating galaxy transformation as a result of interactions. It has been established that the evolutionary sequence…
FEASTS Combined with Interferometry (IV): Mapping HI Emission to a limit of in Seven Edge-on Galaxies
Dong Yang, Jing Wang, Zhijie Qu +17
We present a statistical study of the neutral atomic hydrogen (HI) gas extending into the circumgalactic medium perpendicular to the disk for 7 edge-on galaxies with inclinations a…
FEASTS: The Fate of Gas and Star Formation in Interacting Galaxies
Shun Wang, Jing Wang, Karen Lee-Waddell +3
We use HI data from the FAST Extended Atlas of Selected Targets Survey (FEASTS) to study the interplay between gas and star formation of galaxies in interacting systems. We build c…
WALLABY Pilot Survey: kNN identification of perturbed galaxies through HI morphometrics
B. W. Holwerda, Helga Dénes, J. Rhee +11
Galaxy morphology in stellar light can be described by a series of "non-parametric" or "morphometric" parameters, such as concentration-asymmetry-smoothness, Gini, , and Se…
WALLABY Pilot Survey: Star Formation Enhancement and Suppression in Gas-rich Galaxy Pairs
Qifeng Huang, Jing Wang, Xuchen Lin +16
Galaxy interactions can significantly affect the star formation in galaxies, but it remains a challenge to achieve a consensus on the star formation rate (SFR) enhancement in galax…
