Query: Evolution of AGN and Stellar Formation through Radio Surveys   The change in the slope of the radio source counts suggests the emergence of
a new population of radio galaxies at mJy and sub-mJy levels. Our understanding
of such faint radio sources has advanced over the last decade through
increasingly sensitive radio surveys and follow-up works at optical wavelength.
The sub-mJy population seems to include both star forming galaxies and
classical (AGN-powered) radio sources, but the relative importance of the two
classes is still debated. Recent results are reviewed and discussed.
