Astrophysical Sources of Stochastic Gravitational Radiation in the Universe

Stochastic gravitational waves (GW) associated with unresolved astrophysical sources at frequency bands of the ongoing GW interferometers LIGO/VIRGO and LISA are studied. We show that GW noise from rotating galactic neutron stars with low magnetic fields may reach the advanced LIGO sensitivity level at frequency f 100 Hz. Within LISA frequency band (10⁻⁴-10⁻¹ Hz), the GW background from galactic binary stars is shown to mainly contribute up to a frequency of 3.10⁻² Hz, depending on the galactic rate of binary white dwarf mergers. To be detectable by LISA, relic GW backgrounds should be as high as ΩGWh₁₀₀²>10⁻⁸ at 10⁻² Hz.
