Parallel sessions

Next-generation radio surveys with unprecedented sky coverage and depth are now starting to arrive, capitalising on the commissioning of a number of SKA pathfinder instruments like ASKAP, MeerKAT, Apertif, LOFAR, and MWA. In order to make sense of these data, more precise models of the radio sky and its constituent source populations are being developed through a combination of observations and simulations. This session is split into two parts:
(i) Sky models: Recent developments in modelling and simulating source populations and distributions at radio wavelengths, including galactic diffuse emission and extragalactic sources, and accounting for instrumental and observational effects.
(ii) HI science: Cosmic evolution of HI, HI as a function of environment, and mass and dynamics of HI in galaxies, including discussion on what observational properties such as HI mass, morphology, and kinematics are telling us about these key topics, and how state-of-the-art statistical methods can be used to extract this information and apply it to current and upcoming surveys.
