摘要：

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.
