Abstract:

In this poster we outline an ongoing broadband all-sky search for periodic signals from isolated spinning neutron stars using data taken from LIGO's fifth science run. This search is based on the Hough transform, which accounts for Doppler and amplitude modulations, and for source spindown, over long time intervals, starting from short Fourier transforms of the data. The pipeline performs a multi-interferometer search using the full first and second year of S5 data, together with a coincident step among the candidates produced in the search on the two years and it also includes a Chi2-Veto.
