Abstract

We searched for evidence of the presence of AGN in LINERs using X-ray images and spectra up to 10 keV obtained with ASCA. We detected hard point-like nuclear sources with X-ray luminosities of 1040 - 1041 ergs s-1 from LINER 1s. Their Hα luminosities are positively correlated with the X-ray luminosities. These facts strongly support that these LINER 1s are ionized by low luminosity AGN. LINER 2s in the present sample have systematically lower X-ray to Hα luminosity ratio (LX/LHα) suggesting that there exist other ionizing source or that the AGN is heavily obscured even at energies above 2 keV. X-ray properties of low luminosity AGNs are also discussed.
