Abstract

We report x-ray observations of the first six sources observed with ROSAT in our study of low-power radio galaxies. Spatial and spectral measurements show that both resolved (thermal) and unresolved X-ray emission in a single source are typical, although the relative strength and size of the resolved component varies between objects. The unresolved X-ray component correlates well with the core radio emission and may be dominated by nonthermal emission associated with an inner radio jet.
