Abstract.

We use images of the Hubble Deep Fields (HDFs) to estimate the universal star formation density (SFD) and its evolution. We find that it increases with z to the highest redshifts explored, and that cosmological dimming must be taken into account to measure this quantity. A direct comparison with the properties of high-z DLAs shows perfect agreement with our analysis, providing encouraging evidence to its validity.
