F-statistic search for white-dwarf binaries in the first Mock LISA Data Challenge‡

چکیده
The F-statistic is an optimal detection statistic for continuous gravitational waves, i.e. long-duration (quasi-)monochromatic signals with slowlyvarying intrinsic frequency. This method was originally developed in the context of ground-based detectors, but it is equally applicable to LISA where many signals fall into this class of signals. We report on the application of a LIGO/GEO Fstatistic code to LISA data-analysis using the long-wavelength limit (LWL), and we present results of our search for white-dwarf binary signals in the first Mock LISA Data Challenge. Somewhat surprisingly, the LWL is found to be sufficient – even at high frequencies – for detection of signals and their accurate localization on the sky and in frequency, while a more accurate modelling of the TDI response only seems necessary to correctly estimate the four amplitude parameters.

Mock LISA Data Challenge 2 : F - statistic Search for white - dwarf binaries
We use the F -statistic, a coherent matched-filtering detection statistic first introduced by Jaranowski et al. [6] in the context of the search for continuouswave signals in ground based detectors. This method has been implemented by the LIGO Scientific collaboration in LAL/LALApps [8], and is currently used in the search for quasi-periodic GW signals from spinning neutron stars (e.g. see [1])...

متن کاملDetecting white dwarf binaries in Mock LISA Data Challenge 3
We present a strategy for detecting gravitational wave signals from the Galactic white dwarf binaries in the Mock LISA Data Challenge 3 (MLDC3) and estimate their parameters. Our method is based on the matched filtering in the form of the F-statistic. We perform the search on three-dimensional space (sky coordinate and frequency of gravitational wave) below 3 mHz and include the fourth paramete...

We report on our F-statistic search for white-dwarf binary signals in the Mock LISA Data Challenge 1B (MLDC1B) . We focus in particular on the improvements in our search pipeline since MLDC1, namely refinements in the search pipeline and the use of a more accurate detector response (rigid adiabatic approximation). The search method employs a hierarchical template-grid based exploration of the p...
