Galaxies decomposition with spiral arms -- II: A multiwavelength case study of M 51
Alexander A. Marchuk, Ilia V. Chugunov, George A. Gontcharov +7
Spiral structure can contribute significantly to a galaxy's luminosity. However, only rarely are proper photometric models of spiral arms used in decompositions. As we show in the…
Isochrone fitting of Galactic globular clusters -- V. NGC6397 and NGC6809 (M55)
George A. Gontcharov, Charles J. Bonatto, Olga S. Ryutina +8
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…
New Interstellar Extinction Maps Based on Gaia and Other Sky Surveys
G. A. Gontcharov, A. A. Marchuk, M. Yu. Khovrichev +5
We present new three-dimensional (3D) interstellar extinction maps in the and Gaia filters within 2 kpc of the Sun, a 3D differential extinction (dust spatial distribution…
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…
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…
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…
Isochrone fitting of Galactic globular clusters -- IV. NGC6362 and NGC6723
George A. Gontcharov, Maxim Yu. Khovritchev, Aleksandr V. Mosenkov +10
We present new isochrone fits to the colour-magnitude diagrams of the Galactic globular clusters NGC\,6362 and NGC\,6723. We utilize 22 and 26 photometric filters for NGC\,6362 and…
The distribution of dust in edge-on galaxies: I. The global structure
Aleksandr V. Mosenkov, Pavel A. Usachev, Zacory Shakespear +9
In this first paper in a series we present a study of the global dust emission distribution in nearby edge-on spiral galaxies. Our sample consists of 16 angularly large and 13 less…
Evolution of dust grain size distribution and grain porosity in galaxies
Hiroyuki Hirashita, Vladimir B. Il'in
The radiative properties of interstellar dust are affected not only by the grain size distribution but also by the grain porosity. We develop a model for the evolution of size-depe…
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…
Evolution of dust porosity through coagulation and shattering in the interstellar medium
Hiroyuki Hirashita, Vladimir B. Il'in, Laurent Pagani +1
The properties of interstellar grains, such as grain size distribution and grain porosity, are affected by interstellar processing, in particular, coagulation and shattering, which…
Mid-infrared extinction and fresh silicate dust towards the Galactic Center
Nikolai V. Voshchinnikov, Thomas Henning, Vladimir B. Il'in
We interpret the interstellar extinction observed towards the Galactic Center (GC) in the wavelength range $λ= 1 - 20\,\mkm$. Its main feature is the flat extinction at $3 - 8\,\mk…
Polarizing efficiency as a guide of grain growth and interstellar magnetic field properties
N. V. Voshchinnikov, V. B. Il'in, H. K. Das
We interpret the relation between the polarizing efficiency and the wavelength of the maximum polarization observed for 17 objects (including 243 stars…
Imaging polarimetry of the rotating Bok globule CB67
M. S. Prokopjeva, A. K. Sen, V. B. Il'in +2
Polarimetric observations of about 50 stars located in a close vicinity of the Bok globule CB67 having significantly nonspherical shape and rapid rotation are performed. The data o…
Systematic variations of interstellar linear polarization and growth of dust grains
N. V. Voshchinnikov, H. K. Das, I. S. Yakovlev +1
A quantitative interpretation of the observed relation between the interstellar linear polarization curve parameters and characterizing the width and the wavelength…
