Fractal dimension of optical cirrus in Stripe82
Alexander A. Marchuk, Anton A. Smirnov, Aleksandr V. Mosenkov +4
The geometric characteristics of dust clouds provide important information on the physical processes that structure such clouds. One of such characteristics is the fractal dim…
Isochrone fitting of Galactic globular clusters -- III. NGC\,288, NGC\,362, and NGC\,6218 (M12)
George A. Gontcharov, Maxim Yu. Khovritchev, Aleksandr V. Mosenkov +6
We present new isochrone fits to colour-magnitude diagrams of the Galactic globular clusters NGC\,288, NGC\,362, and NGC\,6218 (M12). We utilize a lot of photometric bands from the…
Investigation of the parameters of spiral pattern in galaxies: the arm width
Aleksandr Mosenkov, Sergey Savchenko, Alexander Marchuk
In this work we determine the parameters of spiral structure for a sample of face-on spiral galaxies. In practice, the solution of this problem is a hard task because of the divers…
A multi-wavelength study of spiral structure in galaxies. I. General characteristics in the optical
Sergey Savchenko, Alexander Marchuk, Aleksandr Mosenkov +1
Different spiral generation mechanisms are expected to produce different morphological and kinematic features. In this first paper in a series we carefully study the parameters of…
Gravitational instability and star formation in NGC 628
A. A. Marchuk
The gas-stars instability criterion for infinitesimally thin disc was applied to the galaxy NGC 628. Instead of using the azimuthally averaged profiles of data the maps of the gas…
Reconstructing the velocity dispersion profiles from the line-of-sight kinematic data in disc galaxies
A. A. Marchuk, N. Y. Sotnikova
We present a modification of the method for reconstructing the stellar velocity ellipsoid (SVE) in disc galaxies. Our version does not need any parametrization of the velocity disp…
