Introduction to the Analysis of Low-frequency Gravitational Wave Data *

The space-based gravitational wave detector LISA will observe in the low-frequency gravitational-wave band (0.1 mHz up to 1 Hz). LISA will search for a variety of expected signals, and when it detects a signal it will have to determine a number of parameters , such as the location of the source on the sky and the signal's polarisation. This requires pattern-matching, called matched filtering, w...

Gravitational Wave Signal identification and transformations in time-frequency domain

A gravitational wave signal carries information about an astrophysical source, a time varying quantity that has to be analyzed in the time frequency domain. There are varieties of transforms that can be applied to understand the complex evolution time-varying frequencies and chirps. This paper discusses various techniques of transforms that can be applied to various categories of this problem t...

Time-delay analysis of LISA gravitational wave data: Elimination of spacecraft motion effects

LISA ~Laser Interferometer Space Antenna! is a proposed mission which will use coherent laser beams exchanged between three remote spacecraft to detect and study low-frequency cosmic gravitational radiation. Modeling each spacecraft as moving almost inertially, rigidly carrying a laser, beam splitters and photodetectors, we previously showed how the measured time series of Doppler shifts of the...

Data Analysis of Gravitational Wave Signals from Coalescing Binaries

In this lecture I shall be dealing with the techniques of Data analysis which will be used to extract the gravitational wave signal from the noisy output of the gravitational wave detector. The inspiral of binary systems consisting of compact objects such as black-holes and neutron stars can be well modelled. The knowledge of the signal waveform enables us to design detection strategies which a...

Gravitational-wave astronomy: the high-frequency window

As several large scale interferometers are beginning to take data at sensitivities where astrophysical sources are predicted, the direct detection of gravitational waves may well be imminent. This would (finally) open the long anticipated gravitational-wave window to our Universe, and should lead to a much improved understanding of the most violent processes imaginable; the formation of black h...
