Gravitational wave signals from ensemble of rotating neutron stars in Galaxy |
|
Abstract |
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., due to magnetic field. 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 analyse 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 and above 40 Hz with Advanced Virgo/Ligo observation if the mean asymmetry is as high as $10^{-6}$. |
