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…

Galactic disc warps from to modern epoch: ruling out observational effects

Ilia V. Chugunov, Vladimir P. Reshetnikov, Alexander A. Marchuk

A significant fraction of galaxies show warps in their discs, usually noticeable at its periphery. The exact origin of this phenomenon is not fully established, although multiple w…

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…

Foreground Extinction to Extended Celestial Objects -- I. New Extinction Maps

G. A. Gontcharov, A. A. Marchuk, S. S. Savchenko +5

We present a new two-dimensional (2D) map of total Galactic extinction, , across the entire dust half-layer from the Sun to extragalactic space for Galactic latitudes…

Galactic warps: from cosmic noon to the current epoch

Vladimir P. Reshetnikov, Ilia V. Chugunov, Alexander A. Marchuk +6

Approximately half of all disc galaxies exhibit appreciable warps in both their stellar and HI discs. The typical warp amplitude is small (a few degrees), and only becomes noticeab…

Examination of the functional form of the light and mass distribution in spiral arms

Ilia V. Chugunov, Alexander A. Marchuk, Sergey S. Savchenko

Spiral arms are a common feature of local galaxies, but the exact form of the distribution of mass and light in them is not well known. In this work, we aim to measure this distrib…

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…

Less Wound and More Asymmetric: JWST Confirms the Evolution of Spiral Structure in Galaxies at

Ilia V. Chugunov, Alexander A. Marchuk, Aleksandr V. Mosenkov

Spiral galaxies are ubiquitous in the local Universe. However the properties of spiral arms in them are still not well studied, and there is even less information concerning spiral…

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…

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…

A multiwavelength study of spiral structure in galaxies. II. Spiral arms in deep optical observations

Aleksandr V. Mosenkov, Andrey D. Panasyuk, Savanah Turner +7

In this paper, we look to analyse the spiral features of grand-design, multiarmed, and flocculent spiral galaxies using deep optical imaging from DESI Legacy Imaging Surveys. We ex…

The possible evolution of pitch angles of spiral galaxies

V. P. Reshetnikov, A. A. Marchuk, I. V. Chugunov +2

The origin and maintenance of spiral structure in galaxies, the correlation between different types of spiral structure and several proposed mechanisms for their generation, and th…

Galaxies decomposition with spiral arms -- II: 29 galaxies from SG

Ilia V. Chugunov, Aleksandr V. Mosenkov, Alexander A. Marchuk +7

Spiral structure can occupy a significant part of the galaxy, but properly accounting for it in photometric decomposition is rarely done. This may lead to significant errors in the…
