- Title
Galactic wind in NGC 4460: New observations.
- Authors
Oparin, D.; Moiseev, A.
- Abstract
NGC 4460 is an isolated lenticular galaxy, in which galactic wind has been earlier discovered as a gas outflow associated with circumnuclear regions of star formation. Using the results of observations in the H α line with the scanning Fabry-Perot interferometer on the SAO RAS 6-m telescope, we studied the kinematics of the ionized gas in this galaxy. The parameters of gas outflow from the plane of the galactic disk were refined within a simple geometric model. We show that it is impossible to characterize the wind by a fixed velocity value. Characteristic outflow velocities are within 30-80 km s, and they are insufficient to make the swept-out matter ultimately leave the galaxy.
