Can theLaser Interferometer Space AntennaResolve the Distance to the Large Magellanic Cloud?

The Laser Interferometer Space Antenna (LISA) is expected to detect N ~ 22[x10^(+/- 1)] close white dwarf binaries in the Large Magellanic Cloud (LMC)through their gravitational radiation with signal-to-noise ratios greater than10 in observational durations of 3 years or more. In addition to chirp mass,location on the sky, and other binary parameters, the distance to each binaryis an independent parameter that can be extracted from an analysis ofgravitational waves from these binaries. Using a sample of binaries, one canestablish the mean distance to the LMC as well as the variance of thisdistance. Assuming no confusion noise at frequencies above 2 mHz, LISA mightdetermine the LMC distance to ~ 4.5 (N/22)^(1/2)% and the line of sight extentof LMC to ~ 15 (N/22)^(1/4)$%, relative to its distance, at the one-sigmaconfidence. These estimates are competitive to some of the proposed directgeometric techniques to measure LMC distance in future with missions such asSIM and GAIA.Comment: 4 pages, 1 figure panel. ApJL submitte
