Title: Observations of quasar feedback
Abstract: Quasars are now thought to have made critical impact on galaxy formation. Feedback
from accretion onto supermassive black holes is implicated in establishing the black hole mass vs
galaxy bulge correlations and in limiting the maximal mass of galaxies. In this talk, I will review
the indirect evidence for quasar feedback as required by galaxy formation models. I will then
present recent multi-wavelength observations of powerful quasar-driven winds and outflows on
galaxy-wide scales. These data may provide direct observational evidence for one of the longstanding
paradigms in galaxy formation.
