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 the Evolutionary Counterparts of the Milky Way

I. B. Vavilova, A. M. Dmytrenko, D. V. Dobrycheva +8

The search for Milky Way (MW) analogues has traditionally relied on similarity in a limited set of present-day global properties, including morphology. However, galaxies with simil…

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…
