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. |
