We fit various colour-magnitude diagrams (CMDs) of the Galactic globular clusters NGC\,6397 and NGC\,6809 (M55) by isochrones from the Dartmouth Stellar Evolution Database (DSED) a…
A new, purely photometric method for determination of resonance locations in spiral galaxies
Alexander A. Marchuk, Aleksandr V. Mosenkov, Ilia V. Chugunov +3
The knowledge of the positions of the corotation resonance in spiral arms is a key way to estimate their pattern speed, which is a fundamental parameter determining the galaxy dyna…
The problem of dust attenuation in photometric decomposition of edge-on galaxies and possible solutions
Sergey Savchenko, Denis Poliakov, Aleksandr Mosenkov +6
The presence of dust in spiral galaxies affects the ability of photometric decompositions to retrieve the parameters of their main structural components. For galaxies in an edge-on…
The haloes and environments of nearby galaxies (HERON) -- III. A 45 kpc spiral structure in the GLSB galaxy UGC 4599
Aleksandr V. Mosenkov, R. Michael Rich, Michael Fusco +10
We use a 0.7-m telescope in the framework of the Halos and Environments of Nearby Galaxies (HERON) survey to probe low surface brightness structures in nearby galaxies. One of our…
A Three-Dimensional Analytical Model of the Interstellar Extinction within the Nearest Kiloparsec
G. A. Gontcharov, A. V. Mosenkov, S. S. Savchenko +6
We present a new version of our analytical model of the spatial interstellar extinction variations within the nearest kiloparsec. This model treats the 3D dust distribution as a su…
Evolution of the spiral structure of galaxies from the HST COSMOS field
V. P. Reshetnikov, A. A. Marchuk, I. V. Chugunov +2
We have investigated the pitch angle () of the spiral arms of galaxies in the Hubble Space Telescope COSMOS field. The sample consists of 102 face-on galaxies with a two-armed p…
Prospects for future studies using deep imaging: Analysis of individual Galactic cirrus filaments
Anton A. Smirnov, Sergey S. Savchenko, Denis M. Poliakov +6
The presence of Galactic cirrus is an obstacle for studying both faint objects in our Galaxy and low surface brightness extragalactic structures. With the aim of studying individua…
Interstellar Extinction in Galactic Cirri in SDSS Stripe 82
G. A. Gontcharov, A. V. Mosenkov, S. S. Savchenko +6
We have applied the method of star counts with Wolf diagrams to determine the interstellar extinction in five Galactic cirri in Sloan Digital Sky Survey (SDSS) Stripe 82. For this…
