Feedback from AGN is thought to be key in shaping the life cycle of their host galaxies by regulating star-formation activity. Therefore, understand impact on star formation, it essential trace molecular gas out which stars form. In this paper we present first systematic study CO properties hosts at z~2 for a sample 27 X-ray selected spanning two orders magnitude bolometric luminosity (Lbol= 10^44.7-10^46.9 erg/s) using ALMA Band 3 observations CO(3-2) transition (~1" angular resolution). To search evidence feedback galaxies, compared our with inactive (i.e., non-AGN) PHIBSS survey similar redshift, stellar masses, and SFRs. We used same as consistent proxy mass samples order avoid systematics involved when assuming conversion factors. By adopting Bayesian approach take upper limits into account, analyzed luminosities function masses SFRs, well ratio LCO(3-2)/M* (proxy fraction). The show statistically trends LCO(3-2)-Lfir LCO(3-2)-M* planes. However, there are indications that feature lower (0.4-0.7 dex) than 2-3sigma level focus subset parameters where results better constrained distribution mean LCO(3-2)/M*. even conservatively excitation factor r31, would find AGN, higher r31 exacerbate difference. interpret result hint potential effect activity (e.g., radiation outflows), may able heat, excite, dissociate, and/or deplete reservoir galaxies.
