Abstract

We present deep Chandra X-ray observations of NGC 5005, a LINER-dominated galaxy previously reported to host a broad Hα emission line. The diffuse soft X-ray emission (<3 keV) extends out to ∼800 pc, while harder emission (>3 keV) is confined to the central ∼400 pc. Spatially resolved spectroscopy of the nuclear (r<150 pc) and extended (150
