  2. COSMOS AGN SurveyScience Goals • Deep, wide-field AGN survey, down to Seyfert luminosities at z ~ 3 • Bolometric measures of activity from X-ray, optical, radio and IR data • Proxy for measure of supermassive black hole mass from broad lines • Statistical sensitivity to rare populations (obscured, BAL, etc) • New measure of AGN clustering relative to galaxy large scale structure • Environmental dependence of AGN luminosity and energy distributions • Host galaxies morphologies measured out to z ~ 1 with ACS data • Populations of high redshift (z > 4) quasars with superior statistics • 3D tomography of the IGM using COS spectroscopy of brightest quasars

  3. IMACS limit IMACS limit AGN locus 0.1 < Fx/Fopt < 10 X-Ray Selection Most efficient way to select AGN with x-ray… follow up all objects of iAB < 23.5 with IMACS Secondary targets and objects with iAB > 23.5 picked up by V-COSMOS

  4. z~2.1 QSO z~3.6 QSO z~1.8 QSO ~30 counts/pixel z~0.5 QSO + SF? First Results

  5. Redshift Yields and Projections • Redshifts for targets of 20 counts/pixel or more • > Limited to i’<23.5 • Estimates from pointing 11 projected to 2 deg2
