Scientific paper

ROSAT/PSPC observations of the violently merging FIR galaxies NGC 6240 and Mkn 316 are presented. NGC 6240 showing signs of a strong galactic wind also shows extended X-ray and radio emission. The total X-ray luminosity is 3.8×1042erg s-1 amounting to ≡0.2% of the FIR luminosity of NGC 6240. By contrast, the poorly known compact system Mkn 316 is an unresolved nuclear source with the extreme soft X-ray luminosity of 1.3×1043erg s-1 corresponding to ≡4% of its FIR luminosity, while radio emission is virtually absent. Various models are discussed.
