Description
The nature of the faint (< 1 mJy) radio source population has been a long
standing problem of modern astrophysics and has crucial implications for
the relation between the cosmic history of star formation and black hole evolution in the
Universe. While it appears that in many of these faint sources radio emission might be
associated with massive star formation, the relevance of active galactic nuclei, which
dominate at higher flux densities, is not clear. After a review of the main constituents
of the radio sky, I will present some very recent results on the sub-mJy source population
obtained by using a wealth of deep radio, IR, optical, and X-ray data.
I will also report on some preliminary results on the evolution of this population,
which have implications for future deep surveys.
