... Figure: Massive binary evolutionary track. ... A short glance to this track is sufficient to understand that there are a lot of evolutionary scenario parameters, which affect different stages of the binary evolution. Fortunately, a very limited number of parameters has effect on the compact binary merging rate. ... The most important (and practically unique) parameter changing the galactic binary NS merging rate is the distribution of an additional (kick) velocity imparted to NS at birth. ...

... What are their star formation histories? How does this relate to galaxy populations at higher redshift? What, if anything, do we know about the star formation histories of galaxies at high-z? Do low mass and high mass galaxies evolve differently? Can we find a population of galaxies at low redshift which might correspond to a higher redshift population, i.e. the faint blue galaxies? ... What roles do bursts of star formation have in the evolution of dwarf galaxies? ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...
