Title: Galactic Wind in NGC 4460: New Observations
Author: D. V. Oparin, A. V. Moiseev

NGC4460 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 Halpha 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.

NGC 4460 (also MCG 8-23-41, UGC 7611 and PGC 41069) is a magnitude +11.3 edge-on spiral, or lenticular galaxy located 23 million light-years away in the constellation Canes Venatici.
The galaxy is near to the magnitude +8.0 star HD108574.

The galaxy was discovered by German-British astronomer William Herschel using a 47.5 cm (18.7 inch) f/13 speculum reflector at Windsor Road in Slough, Berkshire, on the 10th April 1788. 

RA 12 28 45.557, Dec +44 51 51.25
