Direct constraints on a quasar wind from observations of the Sunyaev-Zeldovich Effect

A deep observation with ALMA has revealed a probable first direct detection of the Sunyaev-Zeldovich Effect (SZE) from a quasar wind. The low level of the signal suggests that the wind is much weaker than predicted by most theories, having a kinetic luminosity only ~0.01% of the bolometric output of the quasar. However, the bubble produced by the hot wind is comparable in total energy to those produced by radio jets in the intracluster medium of some nearby galaxy clusters, so it is plausible that feedback effects could be associated with this bubble. We only see the SZE on one side of the quasar, as expected from a simple wind model where the contribution of the kinetic and thermal SZEs are comparable. We also discuss other possible origins for the SZE, including a wind from a starburst.
