The Non-Uniform Distribution of Galaxies from Data of the SDSS DR7 Survey

A. O. Verevkin, Yu. L. Bukhmastova, Yu. V. Baryshev

We have analyzed the spatial distribution of galaxies from the release of the Sloan Digital Sky Survey of galactic redshifts (SDSS DR7), applying the complete correlation function…

Constraining the nature of galaxy haloes with gravitational mesolensing of QSOs by halo substructure objects

Yu. L. Bukhmastova, Yu. V. Baryshev

Gravitational lensing of background compact objects like active galactic nuclei and quasars, by extended intermediate mass lenses such as globular clusters and and dark matter clum…

Quasars Lensed by Globular Clusters of Spiral and Elliptical Galaxies

Yu. L. Bukhmastova

Based on the SDSS catalog, we have found new close quasar-galaxy pairs. Quasars projected onto the halos of nearer galaxies are encountered among the multitude of quasars observed…

The Method of a Two-Point Conditional Column Density for Estimating the Fractal Dimension of the Galaxy Distribution

Yu. V. Baryshev, Yu. L. Bukhmastova

We suggest a new method for estimating the fractal dimension of the spatial distribution of galaxies, the method of selected cylinders. We show the capabilities of this method by c…

Globular Clusters as Candidates for Gravitational Lenses to Explain Quasar-Galaxy Associations

Yu. L. Bukhmastova

We argue that globular clusters (GCs) are good candidates for gravitational lenses in explaining quasar-galaxy associations. The catalog of associations (Bukhmastova 2001) compiled…

Influence of gravitational lensing on the determination of the luminosity function of background objects

Yu. L. Bukhmastova

The distribution function of quasars with respect to apparent brightness is given, found under the assumption that quasars are, at least partially, the gravitationally enhanced ima…

Properties of Quasar-Galaxy Associations and Gravitational Mesolensing by Halo Objects

Yu. L. Bukhmastova

A new catalog of 8382 close quasar-galaxy pairs is presented. The catalog was composed using published catalogs of quasars and active galactic nuclei containing 11358 objects, as w…

Gravitational mesolensing by King objects and quasar-galaxy associations

Yu. V. Baryshev, Yu. L. Bukhmastova

The probability of strong gravitational lensing of distant compact objects by transparent lenses with King mass distributions is calculated. Examples of such lenses are globular cl…
