We have been searching the southern hemisphere for hot DAs which can be used as part of the Dark Energy Survey (DES) calibration process. This involves photometric and spectroscopic efforts. We will describe the program and results to date; the overall DES calibration effort; and future plans to finalize our project.
We have been searching for southern hemisphere hot DA white dwarfs for roughly the past 10 years. We are using these stars to refine the absolute (color) calibration of the Dark Energy Survey (DES). Along the way however, we have run across an assortment of interesting (to someone) objects which include quasars, magnetic DAs, coolish DAs, a CV, and several non-DAs. We present some of them here; some with results of follow-up observations. Some we are still following ourselves.
