In agreement with previous studies, we find that most of Lyman Limit systems are ionized by the cosmological background, while higher column density systems seem to be illuminated by the local sources of radiation. In addition, we find that most of Lyman limit systems in our simulations are located within the virial radii of galaxies with a wide range of masses, and are physically associated with them (``bits and pieces'' of galaxy formation).
