NGC 3521 as the Milky Way near twin: spectral energy distribution from UV to radio decameter ranges
O. V. Kompaniiets, I. B. Vavilova, Y. V. Vasylkivskyi +10
Milky Way analogues (MWAs) are usually selected from structural and kinematic properties, but robust SED-based similarity criteria are limited by heterogeneous photometry and incom…
Galaxy rotation curve based on RGB stars from the Gaia DR3 catalogue
P. N. Fedorov, A. M. Dmytrenko, V. S. Akhmetov +8
In this paper, we construct a detailed circular velocity curve of the Milky Way out to 20 kpc based on the radial component of the Jeans equation in cylindrical coordinates, assumi…
Milky Way galaxy-analogs and isolated galaxies with bars: environmental density in the Local Volume
O. V. Kompaniiets, I. B. Vavilova, O. M. Kukhar +6
The environmental density of galaxies within the cosmic web constrains their 3D locations in filaments, voids, groups, and clusters. It traces the distribution of baryons and the i…
Ukrainian Wartime Astronomy and its Prospects
Danilo Albergaria, Kateryna Frantseva, Pedro Russo +20
The Russian invasion of Ukraine damaged or compromised astronomical facilities and has prompted the displacement of researchers. A plan to restore Ukrainian astronomy, rooted in a…
The 2MIG isolated AGNs -- 2. X-ray general properties and peculiarities
O. V. Kompaniiets, A. A. Vasylenko, I. B. Vavilova
We have analysed a sample of 2MIG isolated galaxies hosting AGNs (isolated AGNs) to assess whether their nuclear activity differs from that in denser environments. The isolation cr…
Discovery of the Polar Ring Galaxies with deep learning
D. V. Dobrycheva, O. O. Hetmantsev, I. B. Vavilova +3
The aim of our research is to create a catalog of strong and good candidates for PRGs using existing catalogs of PRGs, develop an image-based approach with machine learning methods…
