Scientific paper

Mrk 273 is an ultraluminous IRAS galaxy undergoing a major merger. A unique soft X-ray source Mrk 273x, 1.3' to the northeast of Mrk 273, was discovered by us. The optical counterpart is a nucleated dwarf galaxy with strong emission lines, typical for Seyfert galaxies. The X-ray luminosity is more than two orders of magnitude higher than that from any other dwarf galaxy. We propose to observe the Mrk 273 system with a 50ksec exposure using the ACIS imaging array, centered on the dwarf Seyfert galaxy. The observation will be used to study the spatial distribution, spectral shape and time variability of Mrk 273x and Mrk 273. Understanding of this system has important implications for the formation of nucleated dwarf galaxies and, if such sources are common, the cosmic X-ray background.
