| dc.description | Using the 100-m Green Bank Telescope, we have conducted a cm-wavelength
search for CO J=1-0 line emission towards the high-redshift, far-infrared luminous
object, HDF850.1 over the redshift interval 3.3 ∼< z∼ < 5.4. Despite the wealth of existing
multi-wavelength observations, and the recent identification of a galaxy counterpart
in deep K′ band (2.2 μm) imaging, an unambiguous spectroscopic redshift has not yet
been obtained for this object. A far-infrared-to-radio wavelength photometric redshift
technique however, predicts a ∼90% probability that the redshift is in the range,
3.3∼ < z∼ < 5.4 (equivalent to an observed redshifted CO J=1-0 emission line frequency,
26.5 >∼ ʋobs >∼ 18.0 GHz), making HDF850.1 a potential occupent of the ‘high-redshift
tail’ of submm selected galaxies. We have also conducted a search for CO J=2-1 line
emission over the narrower redshift range, 3.9 ∼< z∼ < 4.3. Although we do not detect
any CO line emission in this object, our limits to the CO line luminosity are in broad
agreement with the median value measured in the current sample of high-redshift,
submm selected objects detected in high-J CO line emission, but not sufficient to fully
test the validity of the photometric redshift technique. | |
