eMERGE is an ambitious Legacy survey to exploit e-MERLIN's unique combination of sensitivity and spatial resolution to study the formation and evolution of star-forming galaxies and AGN out to redshifts of z > 5.

Principle Investigators: Tom Muxlow (JBCA), Ian Smail (Durham) and Ian McHardy (Southampton)
Time Allocation: 918 hours (e-MERLIN including Lovell Telescope).
Tier 1: 738 hours (360 hours at L-band, 378 hours at C-band). Tier 0: 180 hours (L-band)

These observations will provide a powerful, obscuration-independent tool for measuring the massive star formation and AGN activity in high-redshift galaxies, hence tracing the development of the stellar populations and the black hole growth in the first massive galaxies. With a resolution of 50-200 mas in C- and L-Bands, corresponding to < 0.5-1.5kpc at z > 1, e-MERLIN gives us our first truly reliable view of the distribution of star-formation within typical galaxies at the epoch where the bulk of the stars in the present-day Universe were being formed. e-MERLIN will disentangle the relative contributions of AGN and star-formation, an essential step given the apparently simultaneous growth of the black holes and stellar populations in galaxies. To achieve these goals, we have developed a strategy comprising of nested tiers, which together provide a single, coherent survey addressing fundamental questions about the formation and joint evolution of AGN and galaxies. The completed survey will provide a homogeneous data product with lasting legacy value for the whole astronomical community.
