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…
Peculiar motions of the gas at the centre of the barred galaxy UGC 4056
I. A. Zinchenko, L. S. Pilyugin, F. Sakhibov +6
We derive the circular velocity curves of the gaseous and stellar discs of UGC 4056, a giant barred galaxy with an active galactic nucleus (AGN). We analyse UGC 4056 using the 2D s…
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…
A spectral and photometric study of 102 star forming regions in seven spiral galaxies
A. S. Gusev, F. Sakhibov, A. E. Piskunov +7
We present a study of complexes of young massive star clusters (YMCs), embedded in extragalactic giant HII regions, based on the coupling of spectroscopic with photometric and spec…
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…
Parameters of the brightest star formation regions in the two principal spiral arms of NGC 628
Alexander S. Gusev, Oleg V. Egorov, Firouz Sakhibov
We study photometric properties, chemical abundances and sizes of star formation regions in the two principal arms of the galaxy NGC 628 (M74). The GALEX ultraviolet, optical UBVRI…
Spectroscopy of H II Regions in the Late-Type Spiral Galaxy NGC 6946
Alexander S. Gusev, Firouz Sakhibov, Sergey N. Dodonov
We present the results of spectroscopy of 39 H II regions in the spiral galaxy NGC 6946. The spectral observations were carried out at the 6-m BTA telescope of the SAO RAS with the…
Oxygen and nitrogen abundances of HII regions in six spiral galaxies
Alexander S. Gusev, Leonid S. Pilyugin, Firouz Sakhibov +3
Spectroscopic observations of 63 HII regions in six spiral galaxies (NGC 628, NGC 783, NGC 2336, NGC 6217, NGC 7331, and NGC 7678) were carried out with the 6-meter telescope (BTA)…
