摘要：

We present the measurement of the projected and redshift-space two-point correlation function (2pcf) of the new catalog of Chandra COSMOS-Legacy active galactic nucleus (AGN) at 2.9 <= z <= 5.5 (<L-bol> similar to 10(46) erg s(-1)) using the generalized clustering estimator based on phot-z probability distribution functions in addition to any available spec-z. We model the projected 2pcf, estimated using pi(max) = 200 h(-1) Mpc with the two-halo term and we derive a bias at z similar to 3.4 equal to b. =. 6.6(+0.60) -(0.55), which corresponds to a typical mass of the hosting halos of log M-h. =. 12.83(+0.12) -(0.11) h(-1)M circle dot. A similar bias is derived using the redshift-space 2pcf, modeled including the typical phot-z error sigma(z). =. 0.052 of our sample at z >= 2.9. Once we integrate the projected 2pcf up to pi(max). =. 200 h(-1) Mpc, the bias of XMM and Chandra COSMOS at z =. 2.8 used in Allevato et al. is consistent with our results at higher redshifts. The results suggest only a slight increase of the bias factor of COSMOS AGNs at z greater than or similar to 3 with the typical hosting halo mass of moderate-luminosity AGNs almost constant with redshift and equal to log M-h = 12.92(+0.-13) (0.18) at z - 2.8 and log M-h - 12.83(+0.11) (-0.12) at z similar to 3.4, respectively. The observed redshift evolution of the bias of COSMOS AGNs implies that moderate-luminosity AGNs. still inhabit group-sized halos at z greater than or similar to 3, but slightly less massive than observed in different independent studies using X-ray AGNs. at z less than or similar to 2.
