The Astrocosmic Databases For Multi-Wavelength And Cosmological Properties Of Extragalactic Sources

The article briefly describes the new specially-oriented Astro Space databases obtained with ground-based telescopes and space observatories. As a result, multi-wavelength spectral and physical properties of galaxies and galaxy clusters were analyzed in more details, particularly 1) to study the spectral properties of quasars and the distribution of matter in intergalactic scales using Lyman-alpha forest; 2) to study galaxies (including with active nuclei), especially for the formation of large-scale structures in the Universe and influence of the environment on the internal parameters of galaxies; 3) to estimate a visible and dark matter content in galaxy clusters and to test cosmological parameters and the evolution of matter in a wide range of age of the Universe.
