The Multiwavelength Survey by Yale/Chile (MUSYC) covers 1.2 square degrees of sky to U,B,V,R = 26 and K = 22 (AB), and includes the Extended CDF-S field, home of the largest Chandra survey ever conducted at its depth (0.3 square degrees and 228 ks). The X-ray catalogs of this field (Virani et al. 2006, Lehmer et al. 2005) reveal more than 700 Active Galactic Nuclei (AGN). We used the deep optical catalogs to apply the Lyman-Break technique, which yielded a sample of 84 AGN at 2.7 < z < 3.7. We performed a cross-correlation clustering analysis on these AGN and a sample of 1240 Lyman Break Galaxies at z 3. Here we present results on the clustering amplitude, estimates of the dark matter halo masses and number densities of z 3 AGN, and a measurement of the duty cycle for accretion by the SMBH hosted by these AGN.
