Star formation in the hosts of high-z QSOs: Evidence from Spitzer PAH detections
D. Lutz, E. Sturm, L. J. Tacconi +7
We present Spitzer rest-frame mid-infrared spectroscopy of twelve z~2 mm-bright type 1 QSOs, selected from unlensed and lensed QSO samples and covering a range of AGN optical lumin…

PAH emission and star formation in the host of the z~2.56 Cloverleaf QSO
D. Lutz, E. Sturm, L. J. Tacconi +7
We report the first detection of the 6.2micron and 7.7micron infrared `PAH' emission features in the spectrum of a high redshift QSO, from the Spitzer-IRS spectrum of the Cloverlea…
