  Quasar feedback has most likely a substantial but only partially understood
impact on the formation of structure in the universe. A potential direct probe
of this feedback mechanism is the Sunyaev-Zeldovich effect: energy emitted from
quasar heats the surrounding intergalactic medium and induce a distortion in
the microwave background radiation passing through the region. Here we examine
the formation of such hot quasar bubbles using a cosmological hydrodynamic
simulation which includes a self-consistent treatment of black hole growth and
associated feedback, along with radiative gas cooling and star formation. From
this simulation, we construct microwave maps of the resulting Sunyaev-Zeldovich
effect around black holes with a range of masses and redshifts. The size of the
temperature distortion scales approximately with black hole mass and accretion
rate, with a typical amplitude up to a few micro-Kelvin on angular scales
around 10 arcseconds. We discuss prospects for the direct detection of this
signal with current and future single-dish and interferometric observations,
including ALMA and CCAT. These measurements will be challenging, but will allow
us to characterize the evolution and growth of supermassive black holes and the
role of their energy feedback on galaxy formation.
