Title: Reverberation Mapping of Black Hole X-ray Transients

Abstract: Reverberation mapping has been widely used to explore the broad-line region of AGN, but has only recently been effectively applied to X-ray binaries. This reflects the shorter delay timescales involved, of order seconds, which require demanding time resolutions. We will use the large collecting area of Gemini-South together with the rapid readout of the Acquisition Camera to build on our existing progress in this field. We will perform Quick Response X-ray to optical reverberation mapping on a black hole X-ray transient in outburst with X-ray flux >1 Crab and/or V<14. We will probe the structure of the accretion flow, identifying reprocessing sites (the accretion disk, the heated companion star or both) and exploring the structure of the irradiated disk. These observations will form part of our existing, successful multiwavelength program, and will be coordinated with our approved RXTE observations.
