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 micrometers, and narrow-band images at 2.165 and 2.125 µm 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 of ~100 times that of a present-day L* galaxy. The interaction suggests and 'age' of this galaxy of ≃ 10^9 yr. The Hα emission is resolved as a source of diameter ≃ 5 kpc, suggesting that a starburst contributes to the observed Hα emission. There is an excess of objects in the FSC 10214+4724 field that could represent galaxies in an associated cluster.

Additional Information:© 1994 American Astronomical Society. Received 1993 July 13; accepted 1993 October 12. Based on observations obtained at the W. M. Keck Observatory, which is operated jointly by the California Institute of Technology and the University of California. The W. M. Keck Observatory is operated as a scientific partnership between the California Institute of Technology and the University of California. It was made possible by the generous gift of the W. M. Keck foundation, and the support of its president, Howard Keck. We are most grateful for their visionary endowment that has made possible the first of the next generation of telescopes. It is a pleasure to thank E. Stone, W. Frazier, W. Sargent, S. Faber, E. Romano, and W. Lupton and all of the many devoted people whose unflagging efforts have made possible the success of the W. M. Keck Observatory. We thank R. Blandford and S. Phinney for discussions and P. Eisenhardt for providing data in advance of publication. Infrared astronomy at Caltech is supported in part by grants from the NSF and NASA.
