Abstract:
    We report on the measurement of the physical properties (rest-frame
    K-band luminosity and total stellar mass) of the hosts of 89
    broad-line (type-1) active galactic nuclei (AGNs) detected in the
    zCOSMOS survey in the redshift range 1<z<2.2. The unprecedented
    multi-wavelength coverage of the survey field allows us to disentangle
    the emission of the host galaxy from that of the nuclear black hole in
    their spectral energy distributions (SEDs). We derive an estimate of
    black hole masses through the analysis of the broad MgII emission
    lines observed in the medium-resolution spectra taken with VIMOS/VLT
    as part of the zCOSMOS project.

Description:
    Our AGN sample consists of the subsample of objects in the zCOSMOS
    bright spectroscopic catalog (Lilly et al. 2007, Cat. J/ApJS/172/70)
    for which one or more broad emission lines have been identified in the
    spectrum. The zCOSMOS bright sample consists, at the times of writing,
    of 10644 (medium resolution, MR) spectra observed with the VIMOS
    multi-object spectrograph on ESO-VLT in the COSMOS field.
