ABSTRACT
Low-ionization nuclear emission regions (LINERs) are quite common, occuring in at least 1/3 of all galaxies, and more frequently in specific galaxy types. The nature of the undrlying power source remains controversial since photionization from a low-luminosity AGN, photoionization by hot stars, and shock ionization are all plausible excitation mechanisms of the line-emitting gas. LINERs may well be a heterogeneous population. We propose to observe a small sample of 4 such objects with ACIS-I to address the question of their power source. We will exploit the ability of AXAF to deliver high-resolution X-ray images as well as spatially resolved spectra up to 10 keV to test the competing scenarios.
