A new generation of radio telescopes will dramatically improve our view of the radio sky over the coming decade. Arrays with large numbers of wide bandwidth receivers - such as JVLA, LOFAR, the SKA, and precursors - promise to open up a range of exciting new scientific opportunities, from uncovering the detailed physics of radio emission in individual galaxies, to surveying cosmic structure on the very largest scales. This series covers a broad range of topics concerning the science that will be possible with new radio telescopes. It is divided into 3 sessions:

1. Uncovering the physics of extragalactic radio sources – This session focuses on understanding extragalactic radio sources through the detailed study of small samples and individual objects, with a particular emphasis on outstanding questions that can now be addressed using the new generation of radio interferometers. This includes (but is not limited to) galaxy evolution, galaxy clusters, radio galaxies, AGN feedback, cosmic magnetism, and extragalactic star formation. We also welcome abstracts relating to simulations, modelling and theory that can be tested with radio observations.

2. Current and future surveys - While the full SKA is still several years away, the precursor and pathfinder facilities are already in advanced stages. This session looks at the status of existing and ongoing radio surveys and planned surveys with SKA pathfinders, including, but not limited to, continuum and spectral line observations. We welcome abstracts focused on results extracted from existing large radio surveys, and the transformational science possible with upcoming observations with new radio facilities.

3. Cosmology with radio telescopes - This session focuses on the cosmological applications of current and future radio surveys, with a particular emphasis on precision cosmology and new tests of fundamental physics that will be enabled by "all-sky" surveys with the SKA and its contemporaries. We welcome cosmology-focused abstracts on a range of topics, including 21cm intensity mapping, HI and continuum galaxy surveys, cross-correlations and synergies with other probes, cosmology theory and simulations, and survey data analysis and statistical techniques.
