BeppoSAX observations of LINER-2 galaxies
  We present BeppoSAX observations of 6 ``type-2'' LINER and ``transition'' galaxies (NGC3379, NGC3627, NGC4125, NGC4374, NGC5195 and NGC5879)from the   Ho et al. (1997) spectroscopic sample of nearby galaxies. All objects are detected in the 2-10 keV band, having luminosities in the range L(2-10 keV)   ~ 1x10^{39}- 1x10^{40} erg s-1. The PDS upper limits above 10 keV place constraints on the presence of a heavily obscured AGN in the case of NGC3379 and NGC4125. No significant variability is detected in any of the objects.   The spectra are described in most cases by a simple power-law model with a spectral slope of 1.7-2.5 while there is evidence neither for a significant absorption above the Galactic nor for an FeK emission line. Therefore, based on the spectral properties alone, it is difficult to differentiate between a low-luminosity AGN or a star-forming galaxy scenario.   However, imaging observations of NGC3627 and NGC5195 with   Chandra ACIS-S reveal very weak nuclear sources while most of the X-ray flux originates either in off-nuclear point sources or in diffuse emission. The above clearly argue in favour of a star-forming origin for the bulk of the X-ray emission, at least in the above two sources.
