Analysis of Galactic cirrus filaments in HSC-SSP high-resolution deep images using artificial neural networks
Denis M. Poliakov, Anton A. Smirnov, Sergey S. Savchenko +6
The existence of Galactic optical cirrus poses a challenge for observing faint objects within our Galaxy and dim extragalactic structures. To investigate individual cirrus filament…
Isochrone Fitting of Galactic Globular Clusters -- VII. NGC1904 (M79), NGC4372, and revision of NGC288, NGC362, NGC5904 (M5), NGC6205 (M13), and NGC6218 (M12)
George A. Gontcharov, Sergey S. Savchenko, Olga S. Ryutina +8
We estimate key parameters for the Galactic globular clusters NGC1904 and NGC4372 and update the parameters for NGC288, NGC362, NGC5904, NGC6205, and NGC6218, which were analysed i…
Accurate Decomposition of Galaxies with Spiral Arms: Dust Properties and Distribution
A. A. Marchuk, I. V. Chugunov, F. Galliano +8
We analyze three nearby spiral galaxies - NGC 1097, NGC 1566, and NGC 3627 - using images from the DustPedia database in seven infrared bands (3.6, 8, 24, 70, 100, 160, and 250 mic…
Isochrone Fitting of Galactic Globular Clusters -- VI. High-latitude Clusters NGC5024 (M53), NGC5053, NGC5272 (M3), NGC5466, and NGC7099 (M30)
G. A. Gontcharov, S. S. Savchenko, A. A. Marchuk +7
We fit various colour-magnitude diagrams (CMDs) of the high-latitude Galactic globular clusters NGC\,5024 (M53), NGC\,5053, NGC\,5272 (M3), NGC\,5466, and NGC\,7099 (M30) by isochr…
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…
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…
