摘要：

Aims. Radio loud narrow line type 1 galaxies provide us with a fresh look at the blazar phenomenon, the causes of radio loudness, said the physics of jet formation. We present a rnulti-wavelength study of the radio mud narrow line type 1 quasar RX J2314.9+2243, which exhibits some remarkable multi-wavelength properties. It is among the few radio-loud narrow -line type 1 galaxies, with a tentative y-ray detection, is luminous in the infrared, and shows an exceptionally broad and blueshifted 0111] 15007 emission-line component. Methods. In order to understand the nature of this source, we have obtained optical, UV, X-ray, and radio observations of RX J2314.9+2243. Results. Its spectral energy distribution (SED) shows a broad hump extending between the IR and far4 N, a steep radio spectrum and flat X-ray spectrum. Its IR to far UV SED is consistent with a scenario, in which synchrotron emission from a jet dominates the broadband emission, even though an absorption scenario cannot yet be fully excluded. The high blueshift of its very broad [OIII] component, 1260 krn s(-1). is consistent with a face-on view, with the jet (and outflow) pointing towards us. RX J2314.9+2243 likely represents an extreme case of AGN induced feedback in the local universe.
