  The Galaxy is suspected to contain hundreds of millions of binary white dwarf
systems, a large fraction of which will have sufficiently small orbital period
to emit gravitational radiation in band for space-based gravitational wave
detectors such as the Laser Interferometer Space Antenna (LISA). LISA's main
science goal is the detection of cosmological events (supermassive black hole
mergers, etc.) however the gravitational signal from the galaxy will be the
dominant contribution to the data -- including instrumental noise -- over
approximately two decades in frequency. The catalogue of detectable binary
systems will serve as an unparalleled means of studying the Galaxy.
Furthermore, to maximize the scientific return from the mission, the data must
be "cleansed" of the galactic foreground. We will present an algorithm that can
accurately resolve and subtract >10000 of these sources from simulated data
supplied by the Mock LISA Data Challenge Task Force. Using the time evolution
of the gravitational wave frequency, we will reconstruct the position of the
recovered binaries and show how LISA will sample the entire compact binary
population in the Galaxy.
