Near infrared imaging spectroscopy of IRAS FSC 10214+4724: Evidence for a starburst region around an AGN at z=2.3

We report 1'' imaging spectroscopy of the 1.95 to 2.4#mu#m wavelength region in the z=2.284 galaxy IRAS FSC10214+4724. We find that the rest-frame H#alpha# and [NII] emission have different spatial extents. We also detect broad (#DELTA##upsilon#_F_W_Z_P #approx# 3500 km/s) H#alpha# emission. F10214 is a very luminous gravitationally lensed galaxy which intrinsically contains both a type 1 active galactic nucleus, as well as a more extended star forming disk. The AGN and circum-nuclear star formation both contribute significantly to the total luminosity of #approx# 10"1"3L_sun.
