Science from the Pathfinders and the Route to the SKA
I will present an overview of the long baseline science for the SKA and translate the science goals into proposed technical requirements. I will also make comments regarding the possible implementation of the long baseline SKA, with a focus on gradual deployment of resources in alignment with existing infrastructure.

Science from the Pathfinders and the Route to the SKA
The IR/radio properties of galaxies at successively higher redshift have been probed in the past decade using either statistical samples from cosmological survey fields or dedicated samples of specific objects (e.g. sub-mm galaxies). I will mention how the galaxy populations targeted by current radio surveys compare with those that the SKA could detect and briefly discuss -- following the...

Science from the Pathfinders and the Route to the SKA
We present a study that uses very long baseline interferometry to search for binary supermassive black holes at galaxy centres. Such searches are important in experimentally addressing the possibility that supermassive binaries may ``stall'', and never coalesce after the merger of their host galaxies; this would have dramatic (and likely detrimental) consequences for predicted gravitational...

Science from the Pathfinders and the Route to the SKA
The distribution of cold gas in dark matter haloes is driven by key processes in galaxy formation: gas cooling, galaxy mergers, star formation and reheating of gas by supernovae. We compare the predictions of four different galaxy formation models for the spatial distribution of cold gas. We find that satellite galaxies make little contribution to the abundance or clustering strength of cold...

Science from the Pathfinders and the Route to the SKA
New kinds of feed design and signal processing are opening new domains in wide-bandwidth polarimetry. Wide, continuous bandwidths are particularly powerful when applied to the study of rotation measure. Mixed emitting and Faraday-rotating media can create complex frequency structure in the polarization properties of radio sources; such complexities can confuse narrow-bandwidth observations....
