A first test of a sine-Hough method for the detection of pulsars in binary systems using the E4 Virgo engineering run data

摘要

Most of the known pulsars with frequencies lying in the best sensitivity rang e of the Virgo/LIGO/TAMA interferometers belong to binary systems. Accordingly their frequencies are Doppler shifted in an unknown way. We investigate a new method to search for and extract the parameters of such pulsars. A first preliminary test of this method, performed on the Virgo data recorded during the E4 engineering run, is presented. [References: 13]
