The orientation parameters and rotation curves of 15 spiral galaxies
A. M. Fridman, V. L. Afanasiev, S. N. Dodonov +4
We analyzed ionized gas motion and disk orientation parameters for 15 spiral galaxies. Their velocity fields were measured with the H-alpha emission line by using the Fabry-Perot i…
Restoring the full velocity field in the gaseous disk ofthe spiral galaxy NGC 157
A. M. Fridman, O. V. Khoruzhii, V. V. Lyakhovich +5
We analyse the line-of-sight velocity field of ionized gas in the spiral galaxy NGC 157 which has been obtained in the Hαemission at the 6m telescope of SAO RAS. The existence of s…
Giant Cyclones in Gaseous Discs of Spiral Galaxies
A. M. Fridman, O. V. Khoruzhii, E. V. Polyachenko +5
We report detection of giant cyclonic vortices in the gaseous disc of the spiral galaxy NGC 3631 in the reference frame rotating with the spiral pattern. A presence of such structu…
