The $e$MERLIN Galaxy Evolution Survey ($e$MERGE) is an ambitious,multi-tiered extragalactic radio continuum survey being carried out with$e$MERLIN and the VLA at 1.4GHz and 6GHz. Exploiting the unique combination ofhigh sensitivity and high angular resolution provided by radio interferometry,these observations will provide a powerful, obscuration-independent tool fortracing intense star-formation and AGN activity in galaxies out to $z\sim5$. Inour first data release (DR1) we present $e$MERGE Tier 1, a 15-arcmin pointingcentred on the GOODS-N field, imaged at 1.4GHz with the VLA and $e$MERLIN at$\sim 0.28''$ resolution down to an rms sensitivity of $\sim 1.2\,\mu$Jybeam$^{-1}$. This unique radio survey -- unrivaled at 1.4GHz in its combinationof depth, areal coverage and angular resolution in the pre-SKA era -- allows usto localise and separate extended star-forming regions, nuclear starbursts andcompact AGN core/jet systems in galaxies over the past two-thirds of cosmichistory, a crucial step in tracing the apparently simultaneous growths of thestellar populations and central black holes in massive galaxies. In theseproceedings we highlight some early science results from $e$MERGE DR1,including some examples of the sub-arcsecond morphologies and cold dustproperties of 1.4GHz-selected galaxies. $e$MERGE Tier 1 will eventually reachsub-$\mu$Jy beam$^{-1}$ sensitivity at $0.28''$ resolution over a 30-arcminfield, providing crucial benchmarks for deep extragalactic surveys which willbe undertaken with SKA in the next decade.
