SUMMARY:Conference / Symposium:The Astrophysics of Quasars Probed using Broad Absorption Line Quasars
DESCRIPTION:All massive galaxies host a supermassive black hole at their centers. Sufficient gas falling onto the\nblack hole creates a quasar that is dramatically brighter than its host galaxy\; in fact\, quasars are the\nmost luminous persistently emitting objects in the Universe. While the infalling gas powers the\nquasar\, the light it emits can\, in turn\, power an outflow that can be observed in the rest-frame UV\nspectra. However\, despite more than 50 years of study\, the physical properties of quasar winds\,\nincluding fundamentals like the location of the outflow and the wind's potential for influencing\ngalaxy evolution\, are largely unmeasured.\n\nWe pioneered the novel spectral synthesis software SimBAL\, which uses forward modeling and a\nBayesian calibration to extract the physical conditions of the BALQ wind. Using SimBAL\, we are\nlearning about the properties of winds\, and the demographics of the winds is revealing aspects of the\nquasar central engine. In this talk\, I will highlight what we have learned\, and describe some of our\nfuture investigations.
