4 Sep 1999 | | Journal: | Mon.Not.Roy.Astron.Soc. 319 (2000) 318 | | Subject: | astro-ph | | Abstract: | We have carried out targetted sub-mm observations as part of a programme to explore the connection between the rest-frame UV and far-IR properties of star-forming galaxies at high redshift, which is currently poorly understood. On the one hand the Lyman break technique is very effective at selecting z~3 galaxies. On the other hand `blank field’ imaging in the sub-mm seems to turn up sources routinely, amongst which some are star forming galaxies at similar redshifts. Already much work has been done searching for optical identifications of objects detected using the SCUBA instrument. Here we have taken the opposite approach, performing sub-mm photometry for a sample of Lyman break galaxies whose UV properties imply high star formation rates. The total signal from our Lyman break sample is undetected in the sub-mm, at an RMS level of 0.5 mJy, which implies that the population of Lyman break galaxies does not constitute a large part of the recently detected blank-field sub-mm sources. However, our one detection suggests that with reasonable SCUBA integrations we might expect to detect those few LBGs that are far-IR brightest. | | Source: | arXiv, astro-ph/9909092 | | Services: | Forum | Review | PDF | Favorites | |
