| Description |
Observations of different CO transitions in high-z quasars can help usto characterise the physical conditions of the star-forming gas, andimprove current models of the co-evolution of star formation and SMBHgrowth. However, emission of the mm/submm continuum and/or CO lineswith ground-based facilities has been observed only in a relativelysmall number of QSOs, limiting our current knowledge of the dust andmolecular gas properties of this important objects. We propose a lowcost, high-return 10 hour detection experiment that will deliver SPIREphotometry in 3 bands for 103 targets with 0.45 < z < 4.8 (allcurrently known optical/radio selected QSOs lensed by foregroundgalaxies) as first step towards building candidate list for follow up studies. |
