The X-ray emission of a clumpy irregular galaxy from thousands of supernova remnants?
Abstract
The X-ray spectra of Mkn 325 (NGC 7673) were obtained using the Einstein Observatory Imaging Proportional Counter to obtain a 3200 sec exposure. The X-ray flux was aligned with previous radio data. Earlier UV data had indicated that extreme star formation activity was occurring. It is estimated that Mkn experienced a tidal interaction with the neighboring object, Mkn 326, 600 Myr ago, an order of magnitude longer than the present duration of star formation. It is concluded that the Mkn 325-326 interaction did not trigger the star bursts. The star formation processes do agree with a model for the behavior of clumpy galaxies like Mkn 325.
