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…

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…

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…

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…

Spatial orientation and shape of the velocity ellipsoids of the Gaia DR3 giants and subgiants in the Galactic plane

A. M. Dmytrenko, P. N. Fedorov, V. S. Akhmetov +8

We present the results of determining the parameters characterizing the shape and orientation of residual velocity ellipsoids from the Gaia DR3 red giants and subgiants. We show th…

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…
