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 & ASymba: Comparing HI Detection Asymmetries to the SIMBA Simulation
Mathieu Perron-Cormier, Nathan Deg, Kristine Spekkens +15
An avenue for understanding cosmological galaxy formation is to compare morphometric parameters in observations and simulations of galaxy assembly. In this second paper of the ASym…
Photometry and kinematics of dwarf galaxies from the Apertif HI survey
Barbara Å iljeg, Elizabeth A. K. Adams, Filippo Fraternali +13
Context. Understanding the dwarf galaxy population in low density environments is crucial for testing the LCDM cosmological model. The increase in diversity towards low mass galaxi…
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…
