A spectroscopic study of IRAS F10214+4724
The z 1⁄4 2:286 IRAS galaxy F10214 þ 4724 remains one of the most luminous galaxies in the Universe, despite its gravitational lens magnification. We present optical and near-infrared spectra of F10214 þ 4724, with clear evidence for three distinct components: lines of width ,1000 km s from a Seyfert 2 nucleus; & 200 km s lines which are likely to be associated with star formation; and a broad ...
متن کاملIRAS F10214+4724: the inner 100pc
We use new high resolution near-infrared spectroscopy and our previouslypublished optical spectroscopy of the gravitationally-lensed Seyfert-2 galaxy F10214+4724 to study both the links between the starburst and AGN in this object and the properties of the line-emitting clouds in the inner narrow-line region. Close inspection of the rest-frame UV spectrum reveals interstellar or stellar absorpt...

متن کاملSpectroscopic Evidence That the Extreme Properties of Iras F 10214+4724 Are Due to Gravitational Lensing
The extreme bolometric luminosity of IRAS F 10214+4724, and in particular the huge mass in molecular gas inferred from the CO line uxes have led to suggestions that this is a giant galaxy in the process of formation. An arc-like structure and the closeness of a second object suggest, however, that gravitational lensing may be responsible for its anomalously high luminosity and mass. In this pap...
متن کاملHST Observations of the Luminous IRAS Source FSC10214+4724: A Gravitationally Lensed Infrared Quasar
With a redshift of 2.3, the IRAS source FSC 10214+4724 is apparently one of the most luminous objects known in the Universe. We present an image of FSC10214+4724 at 0.8μm obtained with the Hubble Space Telescope WFPC2 Planetary Camera. The source appears as an unresolved (< 0.06) arc 0.7 long, with significant substructure along its length. The center of curvature of the arc is located near an ...
