Using an Assumption about the Monotony of Spiral Arms to Determine the Orientation Angles of Galaxies
S. G. Poltorak, A. M. Fridman
A method is proposed for the determination of the position and inclination angles of the plane of a spiral galaxy based on the assumption that every spiral arm is a monotonic funct…

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…
