Abstract
New observations and theoretical models for the continuous UV-to-radio
spectrum of the ultraluminous protogalaxy candidate IRAS F10214 + 4724
are presented. The radio spectrum at 1.49-8.44 GHz and the resolved
nature of the radio source are compatible with a synchrotron origin of
the radio radiation associated with a luminous starburst. The
submillimeter and FIR spectrum is modeled in terms of emission from both
spherically symmetric dust clouds and an axially symmetric flared disk.
The observed optical to near-IR continuum derived from WHT-FOS
spectroscopy and from UKIRT observations is interpreted in terms of
reddened QSO and starburst models. The continuum is broadly consistent
with emission from a QSO reddened by 1.5 mag of dust. The radio,
submillimeter, FIR, and CO observations of IRAS F10214 + 4724 are
consistent with a powerful starburst early in the life of a massive
galaxy.
