Abstract
We report 1 '' imaging spectroscopy of the 1.95-2.4 mu m wavelength re gion in the z = 2.284 galaxy IRAS FSC 10214+4724. We find that the res t-frame H alpha and [N II] emission have different spatial extents. We also detect broad (Delta(FWZP) approximate to 3500 km s(-1)) H alpha emission. FSC 10214 is a very luminous gravitationally lensed galaxy, which intrinsically contains both a type 1 active galactic nucleus and a more extended star-forming disk. The AGN and circumnuclear star for mation both contribute significantly to the total luminosity of simila r to 10(13) L..
