Description

Rotating neutron stars are likely sources of gravitational radiation for Advanced Virgo and Ligo detectors. We calculated the gravitational waves background produced by the neutron stars in the Milky Way. To determine the signal we adopt a realistic model of the population of neutron stars taking into account the evolution of the rotation period and the magnetic field of each star. The position and velocity of each pulsar is obtained by calculating its motion in the gravitational potential of the Galaxy. We analyse the intensity in the sky and the spectrum of gravitational background. The background will cause a daily variation of the noise level. We found that close and rapidly rotating neutron stars would dominate the total signal. We discuss the detectability of such signal.
