The intrisic brightness of active galactic nuclei (AGN) make them useful probe of the large scale structure of universe at high redshifts. Studies of optically selected AGN have shown these sources may have similar clustering strength as local galaxies. However, as shown by recent Chandra and XMM observations, the optically selected AGN only comprises of ~1/10 of the AGN population probed in hard X-ray at the same optical limits, which means that the optically selected AGN do not represent the whole AGN population. The much higher spatial density of X-ray selected also allow us to probe clustering on scales close to the correlation length, which can hardly be done with optically selected samples. We present the preliminary analysis of the clustering properties of X-ray selected AGN from the Chandra Large Area Synoptic X-ray Survey (CLASXS).
