Source Finding, Modelling and 3D Visualisation of Galaxies

Here I briefly introduce WALLABY, the large-scale neutral hydrogen (H I) survey of the sky, made possible through the development of novel, wide-field Phased Array Feeds (PAFs) currently being deployed on the Australian Square Kilometre Array Pathfinder (ASKAP). I also describe our open-source software package SoFiA, a flexible and highly modular Source Finding Application developed by the WALLABY team, which will be used to find and characterise the 500 000+ galaxies expected to be individually detected in our survey. To model the gas kinematics of 5000 well-resolved WALLABY galaxies we created a pipeline that will facilitate this complex and time-consuming process. I will also briefly report on progress in 3D visualisation of stars and gas in galaxies with the open-source, ray-tracing software Splotch.
