Session 89 - Starburst Galaxies.
Oral session, Wednesday, January 15
I report 1" imaging spectroscopy of the 1.95 to 2.4\mum wavelength region in the z=2.284 galaxy IRAS F10214+4724. I find that the rest-frame H\alpha and [NII] emission have different spatial extents. Furthermore, broad (\Delta v_\mbox\scriptsize FWZP\approx 3500\,\mboxkm/s) H\alpha emission is detected. I conclude that F10214+4724 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 \sim10^13 L_ødot.
