Scientific problems addressed by the Spektr-UV space project (world space Observatory—Ultraviolet)

Werner, K.; Strassmeier, K. G.; Lammer, H. +29 more

The article presents a review of scientific problems and methods of ultraviolet astronomy, focusing on perspective scientific problems (directions) whose solution requires UV space observatories. These include reionization and the history of star formation in the Universe, searches for dark baryonic matter, physical and chemical processes in the i…

Large-scale fluctuations in the number density of galaxies in independent surveys of deep fields

Baryshev, Yu. V.; Shirokov, S. I.; Lovyagin, N. Yu. +1 more

New arguments supporting the reality of large-scale fluctuations in the density of the visible matter in deep galaxy surveys are presented. A statistical analysis of the radial distributions of galaxies in the COSMOS and HDF-N deep fields is presented. Independent spectral and photometric surveys exist for each field, carried out in different wave…
