Mock LISA data challenge for the Galactic white dwarf binaries

Abstract: We present data analysis methods used in detection and the estimation of parameters of gravitational wave signals from the white dwarf binaries in the mock LISA data challenge. Our main focus is on the analysis of challenge 3.1, where the gravitational wave signals from more than 6 × 10 7Galactic binaries were added to the simulated Gaussian instrumental noise. Majority of the signals at low frequencies are not resolved individually. The confusion between the signals is strongly reduced at frequencies above 5 … Show more

“…Several studies have looked at parameter estimation for individual white dwarf binaries in the Milky Way [35][36][37]. We extend these studies to consider how the individual observations can be combined to infer the spatial and mass distributions of white dwarf binaries in the Galaxy.…”

“…The BAM codes themselves, which have been lost to the sands of time, did not model the evolution of a binary's orbital period (nor did Challenge 2). Other existing algorithms which have worn their teeth on the MLDC data sets include an F-statistic maximization scheme using a Nelder-Mead simplex algorithm [11], a hierarchical cleaning algorithm (also employing the Fstatistic) [12] and an MCMC search algorithm featuring a Markovian delayed rejection proposal distribution [13]. Beyond MLDC entries there have been numerous proof of principal studies including (but not limited to), Refs.…”
