| Description |
The nature of the connection between the growth of a black hole via accretion and that of its host galaxy bulge via star formation remains a fundamental question in galaxy evolution. SCUBA-850micron observations of matched samples of high redshift X-ray absorbed and unabsorbed QSOs demonstrated that the X-ray absorbed QSO were far more likely to be detected suggesting that their host galaxies had very high star formation rates. This result implies that the zvirgul2 X-ray absorbed QSO population are undergoing the transition from the main star forming phase and the QSO phase of a massive galaxy. Follow-up X-ray observations of the absorbed X-ray QSOs found that the X-ray absorption is due to an outflowing, ionized wind which is potentially the feedback invoked by theorists to terminate star formation in the host galaxy. However, no QSOs from the samples, X-ray absorbed or unabsorbed, were detected with SCUBA below z=1.5. We propose SPIRE and PACS observations of a sample of 10 X-ray absorbed QSOs in the 1
