Isochrone fitting of Galactic globular clusters - IX. Tip of the red-giant branch for 27 clusters and constraints on new particle physics
G. A. Gontcharov, A. M. Kudashov, O. S. Ryutina +1
Red-giant evolution is sensitive to non-standard channels of energy loss in stellar cores and therefore provides a probe of new physics. Such losses increase the luminosity of the…
Features of the distribution of absorbing matter in the local system
V. I. Sorokina, V. V. Bobylev, G. A. Gontcharov +1
V. I. Sorokina\footnote [99]{e-mail: [email protected]}, V. V. Bobylev, G. A. Gontcharov, A. T. BajkovaA detailed study of the dust distribution in the Loc…
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…
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…
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…
