ENSEMBLE OF GALACTIC ROTATING NEUTRON STARS AS A SOURCE OF GRAVITATIONAL BACKGROUND FOR EINSTEIN TELESCOPE DETECTOR
Session: Poster session
A spinning neutron star is a source of continuous gravitational waves, if its mass distribution is non-axisymmetric. Such asymmetry can be caused by various instabilities and deformations (e.g. Andersson, 2003, Gondek-Rosi ́ska et al. 2003). We have performed calculations of the gravitational waves background produced by the ensemble of rotating neutron stars in the Milky Way. In our calculations we use a model of population of neutron stars which takes into account the distribution of birth places, kicks, and evolution of pulsars. We analyze the spatial shape and the spectrum of such background. We find that the signal is detectable above 20 Hz with a one year Einstein Telescope observations if the mean asymmetry is as high as 1/1000000
