General purpose of the project: verification of the hypotheses that constitute the basis of the standard cosmological model which encountered a number of principal difficulties in recent years. Method: analysis of new observational data (mainly the data of spectral observations of objects with large redshifts) and their comparison with results of calculations allowing for additional factors which were not taken into account in frames of the standard model. The project implies solution of a number of problems:
Statistical analysis of fine-structure doublets in quasar spectra for determination of stronger upper limits (as well as parameters of functional dependences) of possible variations of fundamental physical constants.
Calculation of relative abundances of light nuclides with allowance for the possible variations of the fundamental constants at the nucleosynthesis epoch, assuming that the constants vary simultaneously, according to predictions of modern theories.
Statistical analysis of the space-time distribution of the absorption systems, in order to reveal specific features of the distribution of matter observed in causally disconnected regions of the Universe.
Construction of a model of the maser source in the nucleus of galaxy NGC 4258, in order to determine possible restrictions on physical parameters used for modelling of active galactic nuclei.
