RX J0136.9-3510 is an unusual narrow-line Seyfert 1 galaxy (NLS1). We have detected extended (∼12" or ∼54 kpc at the source frame) soft X-ray emission in the ROSAT High Resolution Imager image, accounting for 20% of the total emission. We have also detected a highly blueshifted (7.6 keV in the source frame) Fe K α line in the ASCA Solid-State Imaging Spectrometer spectrum. This is the first detection of such a highly blueshifted emission line in a NLS1. Near-IR and far-IR studies indicate the presence of a possible starburst component in this NLS1. Physical models of the accretion and/or outflow and of the evolution of this NLS1 are discussed in the context of these results.
