| Description |
Observations of different CO transitions in high-z quasars can help us
to characterise the physical conditions of the star-forming gas, and
improve current models of the co-evolution of star formation and SMBH
growth. However, emission of the mm/submm continuum and/or CO lines
with ground-based facilities has been observed only in a relatively
small number of QSOs, limiting our current knowledge of the dust and
molecular gas properties of this important objects. We propose a low
cost, high-return 10 hour detection experiment that will deliver SPIRE
photometry in 3 bands for 103 targets with 0.45 < z < 4.8 (all
currently known optical/radio selected QSOs lensed by foreground
galaxies) as first step towards building candidate list for follow up studies. |
