... The obtained results lead to the following conclusions: a) the heavy element enrichment had taken place in the Galaxy in a few bursts of its activity rether than in a continuons manner; b) these bursts occured during the callapse of the early Galaxy; c) the star formation had been inhibited in the time of the bursts; d) the metal enrichment did not proceed in the periods of star formation, between these bursts of activity. ...

. The relation between ellipticity and size. Red data points are the observed data; most of them have elongated shapes, and larger galaxies tend to have larger ellipticities. Gray-colored regions represent the probability distributions calculated with the computer simulations, in which two galaxies are located at so close distance that they are blended as an elongated galaxy, as shown in the right pictures schematically.

... Searches for Star Formation in Damped Systems . ... The objective was to measure the star-formation rates in these systems. However, no H emission was detected above our limits of Wm -2 , corresponding to star formation rates ( q 0 =0.5). ... For q 0 =0.5 our limits are in conflict with the star formation rates predicted under the assumption that the high- z DLAs are the fully-formed galactic-disk counterparts of today's massive spiral galaxies. ...

... Let us assume to begin with that there is no source at a given location, only background. Let us calculate the probability that the observed counts at that location are due solely to background. ... The routines described in the present section are designed to take as arguments the probability cutoff (actually a cutoff in likelihood is used) and the background, or expectation value for the counts, and use them to calculate the minimum value of source counts which is detectable at those levels. ...
