Abstract (from CDS):
To compare the 850-µm flux distribution of BALQs with that of the non-BAL quasar benchmark sample, we employ a suite of statistical methods, including survival analysis and a novel Bayesian derivation of the underlying flux distribution. Although there are no strong grounds for rejecting the null hypothesis that BALQs on the whole have the same submm properties as non-BAL quasars, we do find tentative evidence (1-4 per cent significance from a Kolmogorov-Smirnov test and survival analysis) for a dependence of submm flux on the equivalent width of the characteristic Civ BAL. If this effect is real - submm activity is linked to the absorption strength of the outflow - it has implications either for the evolution of active galactic nuclei (AGNs) and their connection with star formation in their host galaxies, or for unification models of AGNs.
