Star formation in QSOs. Obscured vs unobscured AGN. Star formation around lower luminosity AGN. Many AGN ( 20% of optical/X ray/radio AGN) are detected at 250 m at redshifts > 1. Detection rate doesnt appear to depend on AGN luminosity. The far-IR emission appears to be star-formation powered. AGN lived in vigorously star forming galaxies in the past. Both optical obscuration (i.e. type 2 objects) and X-ray absorption appear to be associated with the bright sub-mm population and to be a common feature of star forming AGN. Support to the hypothesis that AGN have an obscured growth phase while their host spheroid is forming Alternatively: the host galaxy ISM contributed to the obscuration Herschel Multi-Tiered Extragalactic Survey - HERMES PI: S. Oliver (Sussex) Conclusions HerMES brings a huge range of AGN into view at far IR/submm wavelengths. Many AGN ( 20% of optical/X ray/radio AGN) are detected at 250 m at redshifts > 1. The far-IR emission appears to be star-formation powered. AGN lived in vigorously star forming galaxies in the past. Detection rate doesnt appear to depend very strong trend on the AGN luminosity. Optical and X ray obscuration/absorption appears to be a common feature of star forming AGN. Conclusions HerMES brings a huge range of AGN into view at far IR/submm wavelengths.
