Synchrotron Emission on the Largest Scales: Radio Detection of the   Cosmic-Web
  Shocks and turbulence generated during large-scale structure formation are predicted to produce large-scale, low surface-brightness synchrotron emission. On the largest scales, this emission is globally correlated with the thermal baryon distribution, and constitutes the "Synchrotron Cosmic- Web". I present the observational prospects and challenges for detecting this faint emission with upcoming SKA pathfinders.
