Gravitational Wave Astronomy: in Anticipation of First
Sources to be Detected

The first generation of long-baseline laser interferometric detectors of gravitational
waves will start collecting data in 2001-2003. We carefully analyse their planned
performance and compare it with the expected strengths of astrophysical sources.
The scientific importance of the anticipated discovery of various gravitatinal wave
signals and the reliability of theoretical predictions are taken into account in our
analysis. We try to be conservative both in evaluating the theoretical uncertainties
about a source and the prospects of its detection. After having considered many
possible sources, we place our emphasis on (1) inspiraling binaries consisting of
stellar mass black holes and (2) relic gravitational waves. We draw the conclusion
that inspiraling binary black holes are likely to be detected first by the initial
ground-based interferometers. We estimate that the initial interferometers will see
2-3 events per year from black hole binaries with component masses
10-15M_\odot, with a signal-to-noise ratio of around 2-3, in each of a network of
detectors consisting of GEO, VIRGO and the two LIGOs. It appears that other
possible sources, including coalescing neutron stars, are unlikely to be detected by
the initial instruments. We also argue that relic gravitational waves may be
discovered by the space-based interferometers in the frequency interval
2x10^{-3}-10^{-2} Hz, at the signal-to-noise ratio level around 3.
