##### AUTHOR #### Itziar Aretxaga ##### TITLE #### Correlations between large-scale structure and high-z AzTEC galaxies ##### ABSTRACT #### AzTEC is a sensitive bolometer camera that, coupled with the 15m JCMT and the 10m ASTE telescopes, has mapped more than 3 sq. deg of the extragalactic sky to depths between 0.7 and 1.1 mJy at 1.1mm, prior to its installation on the 50m LMT. These extragalactic surveys have allowed our scientific team to generate catalogs of ~1000 robustly-detected powerful starbursts and AGN at high-redshifts. The main goal of these surveys is to derive an accurate estimation of the star formation history that takes place in obscured starbursts, and determine if the destinies of these galaxies are the massive spheroids that we detect in the nearby universe. We describe the large scale structure correlations that we have detected in large-area mm maps such as those of COSMOS and SSA22, indicating both amplification by lensing of lower-z structures and association in overdensities at high-z.
