OPTIMus - a survey of massive star-forming regions at OPTical, Infrared, and Millimeter wavelengths
M. S. Kirsanova, A. V. Moiseev, A. M. Tatarnikov +3
This work presents a description of the scientific goals and objectives of OPTIMus (OPTical, Infrared, Millimeter survey of massive star-forming regions), a survey of massive star-…
Gravitational instability and spatial regularity of the gas clouds and young stellar population in spiral arms of NGC 628
V. S. Kostiuk, A. S. Gusev, A. A. Marchuk +1
Context. There is a contradiction between the characteristic spacings in observed regular chains of star-forming regions in the spiral arms of galaxies, ~500 pc, and the estimates…
On the nature of spiral arms in the interacting galaxy M51
F. K. Sakhibov, V. S. Kostiuk, A. S. Gusev +1
In this study, we investigated the radial variation of the azimuthal propagation of star formation across the spiral arms in the nearby galaxy NGC 5194 (M51a) by analysing the spat…
A Comprehensive Analysis on the Nature of the Spiral Arms in NGC 3686, NGC 4321, and NGC 2403
V. Kostiuk, A. Marchuk, A. Gusev +1
In theoretical investigations, various mechanisms have been put forward to explain the emergence of spiral patterns in galaxies. One of the few ways to find out the nature of spira…
Cross-method analysis of co-rotation radii dataset for spiral galaxies
Valeria S. Kostiuk, Alexander A. Marchuk, Alexander S. Gusev
A co-rotation radius is a key characteristic of disc galaxies that is essential to determine the angular speed of the spiral structure , and therefore understand its nature…
