1994ApJ...420L..13M NEAR-INFRARED IMAGING OF FSC 10214+4724 WITH THE W. M. KECK TELESCOPE K. MATTHEWS, B. T. SOIFER, J. NELSON, H. BOESGAARD, J. R. GRAHAM, W. HARRISON, W. IRACE, G. JERNIGAN, J. E. LARKIN, H. LEWIS, S. LIN, G. NEUGEBAUER, M. SIROTA, G. SMITH, AND C. ZIOMKOWSKI Received 1993 July 13; accepted 1993 October 12 ABSTRACT Near-infrared observations of the z = 2.286 IRAS source FSC 10214+4724, made with the near-infrared camera on the W. M. Keck Telescope, are reported. Deep broad-band images at 2.15 and 1.27 microns, and narrow-band images at 2.165 and 2.125 microns with 0.6" to 0.9" seeing show that FSC 10214+4724 consists of at least three distinct components in a compact group of galaxies. The source of the infrared luminosity appears to be in a strongly interacting galaxy that has a luminosity ~100 times that of a present-day L^*^ galaxy. The interaction suggests an "age" of this galaxy of ~10^9^ yr. The H{alpha} emission is resolved as a source of diameter ~5 kpc, suggesting that a starburst contributes to the observed H{alpha} emission. There is an excess of objects in the FSC 10214+4724 field that could represent galaxies in an associated cluster. Subject headings: galaxies: clustering - galaxies: individual (FSC 10214+4724) - galaxies: interactions - galaxies: peculiar - galaxies: starburst - infrared: galaxies
