The 2MIG isolated AGNs -- 4. Linking hot-dust reverberation to spectroscopically predicted BLR scales in IC~5287 and Mrk~845
I. O. Izviekova, I. B. Vavilova, O. V. Kompaniiets +2
We investigate the relation between directly measured hot-dust reverberation scales and spectroscopically predicted broad-line region (BLR) scales in the isolated Seyfert galaxies…
Revealing a multi-zone circumnuclear dust response in UGC~11487 through phase-resolved WISE W1--W2 diagnostics
I. O. Izviekova, O. V. Kompaniiets, I. B. Vavilova
Mid-infrared (MIR) flares provide a direct probe of dust reprocessing in obscured tidal disruption event (TDE) candidates when the primary optical or ultraviolet flare is weak, mis…
Milky Way Near Twins (MWNeTs). I. A Hierarchical Framework for Identifying Candidate Evolutionary Counterparts of the Milky Way
I. B. Vavilova, A. M. Dmytrenko, D. V. Dobrycheva +8
Searches for Milky Way analogues traditionally rely on a limited set of present-day global properties. However, galaxies with similar morphology, stellar mass, star-formation rate,…
The 2MIG isolated AGNs. 3. Optical--IR variability and dust reverberation in the NLSy1 galaxies Mrk~42 and Mrk~493
I. O. Izviekova, I. B. Vavilova, O. V. Kompaniiets +2
This work presents the first dedicated optical--mid-infrared time-domain variability and dust-reverberation analysis of the isolated NLSy1 galaxies Mrk 42 and Mrk 493. We combine Z…
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…
NGC3521 as the Milky Way analogue: spectral energy distributon from UV to Radio and photometric variability
O. S. Pastoven, O. V. Kompaniiets, I. B. Vavilova +1
We studied the multiwavelength properties of NGC 3521, the Milky Way galaxy-twin, from UV- to radio, exploring the data from GALEX for UV-, SDSS for optical, 2MASS, WISE, MIPS (Spi…
An advanced approach for definition of the "Milky Way galaxies-analogues"
Iryna B. Vavilova, Petr M. Fedorov, Daria V. Dobrycheva +5
Our Galaxy - the Milky Way - has certain features of the structure and evolution. The morphological, photometric, kinematic, and chemodynamical properties are usually considered in…
Multiwavelength properties of the low-redshift isolated galaxies with active nuclei modelled with CIGALE
O. Kompaniiets
Using the CIGALE software, we present the preliminary results of a multiwavelength analysis of eighteen low-redshift isolated galaxies with active nuclei (isolated AGNs). This samp…
Nuclear obscuration structure in Mrk 417 based on NuSTAR and Swift/BAT data
O. V. Kompaniiets, A. A. Vasylenko
We present the results of X-ray spectral analysis of the Seyfert type 2 galaxy Mrk 417 observed by the NuSTAR (3-60 keV) and the Swift/BAT (14-150) observatories. The NuSTAR data s…
