Descripción
We perform a wide parameter-space search for continuous gravitational
waves over the whole sky and over a large range of values of the
frequency and the first spin-down parameter. Our search method is based
on the Hough transform, which is a semicoherent, computationally
efficient, and robust pattern recognition technique. We apply this
technique to data from the second science run of the LIGO detectors and
our final results are all-sky upper limits on the strength of
gravitational waves emitted by unknown isolated spinning neutron stars
on a set of narrow frequency bands in the range 200-400Hz. The best
upper limit on the gravitational-wave strain amplitude that we obtain in
this frequency range is 4.43×10-23.
