Description:
The X-ray source MS 0129.2 - 2237 is positionally coincident with an interacting system of galaxies. This paper presents the results of a spectroscopic and photometric investigation of the system, which show that a Seyfert 1.5, a Seyfert 2 nucleus or H II region, or a starburst galaxy, a normal galaxy plus possibly another galaxy where star-forming activity is taking place are strongly interacting. The redshift of the system is z = 0.11. The maximum projected diameter of the envelope common to the four spectroscopically distinct objects is about 98 kpc (H0 = 50 km/s M/pc and q0 = 0.5). The isolated environment in which the system lies suggests that these results present evidence of the final stage of the life of a compact group of galaxies where members are merging into an elliptical galaxy.
