Extended broad-line emission in the obscured Seyfert 1 Nucleus of NGC 4388
Description
Spectroscopic observations of extended off-nuclear broad H-alpha emission (FWZI = about 4000 km/s) are reported for NGC 4388, a galaxy often classified as a type 2 Seyfert. These features are interpreted as scattered radiation from a Seyfert 1 nucleus that is obscured along the line of sight, possibly by the normal interstellar medium in this galaxy. NGC 4388 strongly resembles NGC 1068, another object with a hidden broad-line region, and may be useful for understanding the relationship between Seyfert 1 and Seyfert 2 galaxies. A scattering origin for the off-nuclear broad emission may be tested by spectropolarimetric observations. 18 references
