Query: Luminosity Density Evolution in the Universe and Cosmological Parameters   Star formation history in galaxies is strongly correlated to their
present-day colors and the Hubble sequence can be considered as a sequence of
different star formation history. Therefore we can model the cosmic star
formation history based on the colors of local galaxies, and comparison to
direct observations of luminosity density evolution at high redshift gives a
new test for the cosmological parameters which is insensitive to merger history
of galaxies. The luminosity density evolution in $0<z<1$ observed by the
Canada-France Redshift Survey in three wavebands of 2800{\AA}, 4400{\AA}, and
1$\mu$m indicates that the $\Lambda$-dominated flat universe with
$\lambda_0\sim0.8$ ($>$ 0.53 at 95%CL) is strongly favored. The cosmic star
formation rate (SFR) at $z>2$ is also compared to the latest data of the Hubble
Deep Field including new data which were not incorporated in the previous work
of Totani, Yoshii, & Sato (1997), and our model of the luminosity density of
spiral galaxies taking account of gas infall is consistent with the
observations. Starbursts in elliptical galaxies, which are expected from the
galactic wind model, however overproduce SFRs and hence they should be formed
at $z \gtilde 5$ or their UV emission has to be hidden by dust extinction. The
amound of metals in galactic winds and escaping ionizing photons are enough to
contaminate the Ly$\alpha$ forests or to reionize the universe.
