Karazin popup.description2 Objects of examinations are the cosmological periodicity in spectrums of quasars, jets of quasars and radio galaxies, the toroidal vortexes of degenerated gas, gravitational lenses, a second derivative of a gravitational potential. Goal of the work is a finding of plane waves of a denseness in space distribution of quasars. Research technique - searching of cosmological periodicity is carried out by a method of spectrum analysis, searching of trajectories of the test particles moved in a gravitational field of a toroidal curl is carried out theoretical and numerical modeling, at examination of effect of a diffraction on color of images of builders of a quasar uses a numerical integration and methods Fourier-opticians. At examination of sensitivity of a gradiometer numeral processing methods of a signal have been used. Searching plane waves of a denseness in space distribution of quasars with phases over the range (230 - 700) h-1 Mpc, the most approaching for their detection is lead. Verona - Seti, Verona and sampling of quasars 2QZ 10k used sampling radioloud and sampling of the radiosilent quasars uniformly distributed on the sky, derivated under observational data of the catalogue. The analysis of their selective spectrums of a power is carried out. It is retrieved four plane waves on a significance level 5o10-4. These periodicity with the phases conterminous within the framework of a spectral solution and the close phase, are present at different not intersected samplings. The spectral estimation at allocation of sampling to 5 and 10 segments has confirmed high enough dependability of the detected periodicity. On each of periodicity estimations of parameter of a denseness have been made. Were considered similitude and a discrepancy between images of jets of extragalaxy sources in a wireless and a X-ray band at the expense of synchrotron (a wireless area) or an inverse Compton scattering (X-ray area) which are derivated by the same allocation of relativistic electrons. It is shown, that the heterogeneityof a magnetic field can reduce in the reference differences in the shape and a place of the arrangement of a wireless and X-ray an isophot which depend on that, decreases or the magnetic field on a rim of a radiant grows. Examples of the relevant images are reduced. It has been explored changes of evolution of a self-gravitating toroidal curl, the attraction of test particles to a torus surveyed, three-dimensional mechanical trajectories of test particles in the given gravitational field of a ring built. The carried out examination of effect diffraction at gravitational microlensing on the image of builders of quasar Q2237+0305 has shown a possibility of a modification of color of images. The simplified models of a quasar with narrow enough spatial spectrum have been used some and the obtained values of an index of color appeared poor for an explanation of an index of color which is observed for quasar СQ2237+0305. In case of intersection a quasar of a caustic, with usage of a model with broader spatial spectrum, the obtained index of color is a little bit more, but indicates reddening of the image that contradicts available observational data. A reason of it is, probably, not successful enough choice of a model of a quasar. On the basis of the obtained outcomes still it is impossible to give the unique answer to a problem on a possibility of an explanation of a modification of color in images of a quasar under effect of diffraction and the further examination of this appearance is required. Operation on measuring sensitivity and stability of the laboratory compact gravity gradiometer on a magnetic suspension is carried out, effect of possible disturbances on the observation of a gradiometer is investigated. For improving parameters of this device its some design knots, namely the plan of filing of a legitimate signal have been altered. Product Description popup.authors popup.nrat_date 2020-04-02 Close
