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…

Regular distribution of star formation regions along the spiral arms and rings of disk galaxies
A. S. Gusev, E. V. Shimanovskaya
Last years studies have shown that the spatial regularity in the distribution of young stellar population along the spiral arms and rings of galaxies, previously considered to be r…
