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…
