Query: X-ray luminous star-forming galaxies   We present results from the cross-correlation of the spectroscopic atlas of
Ho etal (1995) with the ROSAT All-Sky Survey Bright Source Catalogue, in an
attempt to understand the X-ray emission mechanisms in nearby galaxies.
  The resulting sample of 45 galaxies consists predominantly of AGN. However,
there are several starforming galaxies spanning a wide range of X-ray
luminosities (~10^{38} - 10^{42} erg s^{-1}). We have analyzed ROSAT and ASCA
data for the two most luminous star-forming galaxies, namely NGC3310 and
NGC3690. We find that their 0.1-10 keV X-ray spectra can be fitted by a soft
thermal plasma of kT$\sim0.8$ keV and a harder component with kT~10-15 keV or a
power-law with Gamma~1.6. These are very similar to the spectra of the
archetypal star-forming galaxies NGC253 and M82.
