IRAS 23532+2513: a compact group including a Seyfert 1 and a starburst galaxy.
Abstract
The very luminous infrared source IRAS 23532 coincides with a compact group of galaxies including MCG 04-01-002, MCG 04-01-003 and MCG 04-01-004. Spectroscopic observations show that the bright-nucleus galaxy MCG 04-01-002 is a Seyfert 1 and the disturbed spiral galaxy MCG 04-01-003 is a starburst galaxy. CCD images in V band reveal that clear tidal interaction exists between those two objects. This is another example of tidal interaction triggering starburst and Seyfert activity.
