In this section we discuss the view of the GW sky above the critical
frequency of the transparency of the stochastic background. At these frequencies
only rapidly rotating NS can generate periodical GW signal (Thorne, 1988[191]),
whereas coalescence of binary NS and supernova
explosions produce burst-like GW. No reliable estimates
of the number of rapidly rotating NS can be obtained at the moment. However,
one can estimate the event rates of supernova explosions and binary NS
coalescence by using current observations and theoretical predictions and
the observed distribution of matter in the vicinity of our Galaxy. As the
closest GW sources are the strongest ones, we will consider Tully's Nearby
Galaxy Catalog (Tully, 1988[194])
comprising 2367 galaxies from a sphere of 50
Mpc in radius. The luminosities are unknown for 596 of these galaxies,
so they cannot be included in the analysis. This catalog is almost complete
up to distances of about 30 Mpc (Figure 43).
