Karazin popup.description2 Research object is gravitational lensing quasars, displays of which are received by action of gravitational areas of more close galaxies in cases, when the last are located near the beam of the sight between quasar and observer. The purpose of work is development of method of detection of dark fabric from analysis of displays gravitational of lensing quasars. Methods of research are photometry with use of different algorithms of processing of display, Fourier-optics, numerical simulation of events microlensing, theoretical analysis and numerical calculations. New approach to analysis of formation of displays gravitational of lensing quasars is developed, which takes into account statistics of gravitational galaxy area induced by plenty of isolated masses located on all thickness of the galaxy. It is shown that distribution of brightness in display of dot source, light of which passed through galaxy, depends on length of the wave and she can be connected with density and distribution of masses in the galaxy. Analysis of observable effects of occurrence of colour connected with passing of the light through “thick” galaxy, can serve by promising tool for the evaluation of the amount of dot masses in the direction of each of the components квазара. Results of work will be used for further researches of the phenomena of gravitational lensing. Product Description popup.authors Вакулік В. Дудінов В. Железняк О. Конічек В.
