The Type II AGN-host galaxy connection

We present a study of optically-selected Type II AGN at 0.5 < z 0.9 from the VIPERS and VVDS surveys, to investigate connection between activity physical properties their host galaxies. The stellar mass is estimated through spectral energy distribution fitting with CIGALE code, star formation rates are derived [OII]$\lambda$3727 $\r{A}$ line luminosity. find that 49% galaxies on or above main sequence (MS), 40% lie in sub-MS locus, 11% quiescent locus. Using [OIII]$\lambda$5007 luminosity as proxy power, we fixed power show bimodal behaviour: systems galaxy <10$^{10}$ M$_{\odot}$, reside along MS starbursts locus (high-SF AGN), while residing massive host-galaxies (>10$^{10}$ M$_{\odot}$) lower level (low-SF AGN). At all masses, offset positively correlated power. interpret this correlation evidence co-evolution host, possibly due availability cold gas. In most powerful below hint, though weak, asymmetry [OIII] profile, likely outflowing gas, consistent scenario which feedback removes available gas halts hosts.
