Abstract
Infrared spectroscopy from one of NASA's Great Observatories, the Spitzer Space Telescope, is used to investigate highly energetic mass outflows from broad absorption line quasars (BALQSOs). We compare the infrared spectra of a sample of BALQSOs with a sample of control quasars to test if these outflows represent a special stage of evolution of a quasar. Specifically, we compare the infrared continuum emission in the two samples to test for differences in the dust temperature, quantity and distribution. These results have implications for understanding how quasars evolve and how they affect their environments.
