The role of deep radio imaging in a multi-wavelength Universe - Edo Ibar Colloquium

We have employed the Giant Metrewave Radio Telescope (GMRT) and the Very Large Array (VLA) to image a few legacy fields such as GOODS, Lockman, and SXDF, reaching noise levels of 5-15 uJy/beam. These images in combination with deep multi-wavelength observations have allowed us to describe the very faint radio population -- found to be mainly composed by star-forming galaxies and radio-faint AGNs extending up to z~3. These deep radio observations play an important role in characterising sub-millimetre galaxies; ­ to pinpoint the galaxy and to provide a proxy for the FIR/radio correlation - therefore to best exploit and drive the present Herschel science. In this talk I will show how our data have allowed us to pursue a wide variety of research projects; the far-infrared/radio correlation as proved by Herschel, the radio spectral index of submm galaxies and the nature of the faint sub-mJy radio population. These new findings are providing an important information for what will be observed and the limitations for the upcoming EMU survey.
