Abstract:
Feedback from active galactic nuclei (AGN) is thought to be key in
shaping the life cycle of their host galaxies by regulating
star-formation activity. Therefore, to understand the impact of AGN on
star formation, it is essential to trace the molecular gas out of
which stars form. In this paper we present the first systematic study
of the CO properties of AGN hosts at z~=2 for a sample of 27 X-ray
selected AGN spanning two orders of magnitude in AGN bolometric
luminosity (logLbol/(erg/s)=44.7-46.9) by using ALMA Band 3
observations of the CO(3-2) transition (∼1" angular resolution). To
search for evidence of AGN feedback on the CO properties of the host
galaxies, we compared our AGN with a sample of inactive (i.e.,
non-AGN) galaxies from the PHIBSS survey with similar redshift,
stellar masses, and star-formation rates (SFRs). We used the same CO
transition as a consistent proxy for the gas mass for the two samples
in order to avoid systematics involved when assuming conversion
factors (e.g., excitation corrections and CO). By adopting a Bayesian
approach to take upper limits into account, we analyzed CO
luminosities as a function of stellar masses and SFRs, as well as the
ratio L'CO(3-2)-M* (a proxy for the gas fraction). The two samples
show statistically consistent trends in the L'CO(3-2)-LFIR and
L'CO(3-2)-M* planes. However, there are indications that AGN feature
lower CO(3-2) luminosities (0.4-0.7dex) than inactive galaxies at the
2-3 level when we focus on the subset of parameters where the results
are better constrained (i.e., LFIR~=1012.2L☉ and
M*>1011M☉) and on the distribution of the mean
log(L'CO(3-2)/M*). Therefore, even by conservatively assuming the
same excitation factor r31, we would find lower molecular gas masses
in AGN, and assuming higher r31 would exacerbate this difference. We
interpret our result as a hint of the potential effect of AGN activity
(such as radiation and outflows), which may be able to heat, excite,
dissociate, and/or deplete the gas reservoir of the host galaxies.
Better SFR measurements and deeper CO observations for AGN as well as
larger and more uniformly selected samples of both AGN and inactive
galaxies are required to confirm whether there is a true difference
between the two populations.
