Abstract:

The F-statistic is a detection statistic for continuous gravitational waves, i.e. long-duration (quasi-)monochromatic signals with slowly-varying intrinsic frequency. This method was originally developed in the context of ground-based detectors, but has also been applied to LISA data, in particular the search for galactic white-dwarf binaries (WDBs). We have generalized the open-source LALApps software suite developed by the LIGO Scientific Collaboration, and used it to perform searches for WDBs in the Mock LISA Data Challenges (MLDCs). We will present the results of this program as applied to the third MLDC, which for the first time includes WDB signals with frequency evolution.
