Gravitational Wave (GW) signature from anisotropy
of source distribution
general introduction of astronomical results will be given
first : coordinates, sidereal time, distance and distribution
of sources in the local universe (within 100 Mpc).
Then, the factors entering the detection of a GW event will
be explained: statistical production rate of events, distance
and orientationof the detector with respect to the source, sensitivity
of the detector. Tensor or scalar waves observed with interferometric
or bar detectors willbe considered.
Finally, we will show that the shape of the count rate of GW
events along the sidereal time directly reflects the actual
distribution of sources.
In return, this gives us the possibility to detect and
sources, simply from the cumulative count of events along
the sidereal time. This method should be very sensitive because
it authorizes very low S/N ratio.
