Parameters of Star Formation Regions in Galaxies NGC 3963 and NGC 7292

A. S. Gusev, F. Kh. Sakhibov, A. V. Moiseev +2

Results of a study of physical parameters of stellar population in star formation regions in galaxies with signs of peculiarity NGC 3963 and NGC 7292 are presented. The study was c…

Physical parameters of stellar population in star formation regions of galaxies

A. S. Gusev, F. Sakhibov, O. V. Egorov +2

We present the results of a study of young unresolved stellar groupings (clusters, OB associations, and their complexes) associated with HII regions, based on the coupling of spect…

Azimuthal propagation of star formation in nearby spiral galaxies: NGC 628, NGC 3726 and NGC 6946

F. Sakhibov, A. S. Gusev, C. Hemmerich

Star formation induced by a spiral shock wave, which in turn is generated by a spiral density wave, produces an azimuthal age gradient across the spiral arm, which has opposite sig…

Properties of galaxies with an offset between the position angles of the major kinematic and photometric axes

L. S. Pilyugin, E. K. Grebel, I. A. Zinchenko +4

We derive the photometric, kinematic, and abundance characteristics of 18 star-forming MaNGA galaxies with fairly regular velocity fields and surface brightness distributions and w…

Spiral arms in CALIFA galaxies traced by non-circular velocities, abundances, and extinctions

F. Sakhibov, I. A. Zinchenko, L. S. Pilyugin +3

We derive maps of the observed velocity of ionized gas, the oxygen abundance, and the extinction (Balmer decrement) across the area of the four spiral galaxies NGC36, NGC180, NGC60…

Star formation rates and the kinematics of gas in the spiral arms of NGC 628

Alexander S. Gusev, Firouz Sakhibov, Yury N. Efremov

Relations between star formation rates along the spiral arms and the velocities of gas inflow into the arms in grand-design galaxy NGC 628 were studied. We found that the radial di…
