Molecular gas distribution in a protogalaxy candidate IRAS F10214 + 4724 - A dense compact nucleus and nondetected extra components

Abstract

Following the paper by Kawabe et al. the results of aperture synthesis observations of CO(J=3→2) emission in IRAS F10214+4724, with the Nobeyama Millimeter Array (NMA), are reported. CO(J=3→2) emission is detected only at the blueshifted half of the CO(J=3→2) velocity range reported in previous single-dish observations; the redshifted half is not detected in our observations. The detected CO(J=3→2) emission is located at a VLA and optical position and shows a compact shape
