A number of applications of High-Frequency Relic Gravitational Wave (HFRGW) detection to astrophysics are identified and a means for detecting them is presented that is sensitive enough to provide useful data. Observation of relic gravitational waves will provide vital information about the birth of the Universe and its early dynamical evolution as well as enable significant direct inferences to be drawn about the value of the Hubble parameter of the early universe and the cosmological scale factor. Other astrophysical applications involve the entropy growth of the early Universe, an ability to rule out alternatives to inflation, to pinpoint the energy scale at which inflation took place and to provide clues about the symmetries underlying new physics at the highest energies. Several alternative HFRGW detectors are described and the proposed Li-Baker HFRGW detector, which is theoretically sensitive to GW amplitudes, A, as small as 10-32, is discussed in detail. It is recommended that plans and specifications for the Li-Baker HFRGW detector be prepared in order to expedite its fabrication.
Comments: 13 pages, possible submission to SPESIF, 2010 as a paper, and talk, and also a source for open discussion of hard ware requirements for a HFGW detector, with applications to detection of astrophysical GW. Inputs to this document await commentary and feed back from the Gravwave team. (I.e. this document may undergo many revisions)
