Abstract / Description of output
The IRAM Interferometer has been used to detect the submillimeter source
HDF 850.1 found by Hughes et al. (1998) in the Hubble Deep Field. The
flux density measured at 1.3 mm (236 GHz) is 2.2+/- 0.3 (1sigma ) mJy,
in agreement with the flux density measured at the JCMT. The flux
densities and upper limits measured at 3.4, 2.8, 1.3, 0.85, and 0.45 mm
show that the emission comes from dust. We suggest that the 1.3 mm dust
source is associated with the optical arc-like feature, 3-593.0, that
has a photometric redshift z~ 1.7. If the HDF 850.1 is at this redshift
and unlensed, its spectral energy distribution, combined with that of
3-593.0, matches closely that of the ultraluminous galaxy VII Zw 31.
Another possibility is that the dust source may be gravitationally
lensed by the elliptical galaxy 3-586.0 at z~ 1. The position of the
dust source agrees within the errors with that of the tentative VLA
radio source 3651+1226.
