Dust covering factor, silicate emission and star formation in luminous QSOs
We present Spitzer IRS low resolution, mid-IR spectra of a sample of 25 high luminosity QSOs at 2<z<3.5. When combined with archival IRS observations of local, low luminosity type-I active galactic nuclei (AGNs), the sample spans five orders of magnitude in luminosity. We find that the continuum dust thermal emission at λrest = 6.7μm is correlated with the optical luminosity, following the non-...

متن کاملStar formation and selective dust extinction in luminous starburst galaxies
We investigate the star formation and dust extinction properties of very luminous infrared galaxies whose spectra display a strong Hδ line in absorption and a moderate [Oii] emission (e[a] spectrum). This spectral combination has been suggested to be a useful method to identify dusty starburst galaxies at any redshift on the basis of optical data alone. We compare the average e(a) optical spect...
متن کاملStar Formation Rate from Dust Infrared Emission
We examine what types of galaxies the conversion formula from dust infrared (IR) luminosity into the star formation rate (SFR) derived by Kennicutt (1998) is applicable to. The ratio of the observed IR luminosity, LIR, to the intrinsic bolometric luminosity of the newly (. 10 Myr) formed stars, LSF, of a galaxy can be determined by a mean dust opacity in the interstellar medium and the activity...
متن کاملSTAR FORMATION IN THE HOSTS OF HIGH-z QSOs: EVIDENCE FROM SPITZER PAH DETECTIONS
We present Spitzer rest frame mid-infrared spectroscopy of 12 z 2 millimeter-bright type 1 QSOs, selected from unlensed and lensed QSO samples and covering a range of AGN optical luminosities L5100 1⁄4 1045Y10 erg s . On top of the AGN continuum, we detect PAH emission from luminous star formation in nine objects individually, as well as in the composite spectrum for the full sample. PAH lumino...
