Abstract

Some open problems in extragalactic astrophysics like: the nature of central massive objects, asymmetric K emission lines from AGNs and quasar-galaxy associations are reviewed.
It is proposed that these facts can be understood within the classical self-consistent multidimensional field theory with dilaton. Dilatonic balls in the centers of galaxies can be responsible for kinematical effects usually attributable to hypothethical massive central black hole. Moreover, peculiarities of emission lines from active galactic nuclei can be explained in a natural way assuming that dilatonic configurations are placed in central parts of AGNs. When we imagine that the large scale structure in the universe could have been built upon dilatonic condensates we are also able to understand qualitatively the existence of associations of high and low reshift objects as well as their main features.
