Abstract:
Radio-loud narrow-line type 1 galaxies provide us with a fresh look at
the blazar phenomenon, the causes of radio loudness, and the physics
of jet formation. We present a multi-wavelength study of the
radio-loud 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 γ-ray
detection, is luminous in the infrared, and shows an exceptionally
broad and blueshifted [OIII]λ5007 emission-line component.
In order to understand the nature of this source, we have obtained
optical, UV, X-ray, and radio observations of RX J2314.9+2243.
Description:
We took spectra of RX J2314.9+2243 with the Opto-Mechanics Research
(OMR) spectrograph attached to the Xinglong 2.16m telescope twice.
The low-resolution spectrum was taken on 1998 September 21 with a slit
width of 2.3", using a Tektronix 1024x1024 CCD as detector. A
300line/mm (200Å/mm) grating was employed to obtain the
broadband optical spectrum. The exposure time was 2100s, at an
airmass of 1.089.
