Gravitational Wave Signatures of Superdense Objects in a Nonsingular Solution of Gravity Theory
J. W. Moffat
Abstract
A massive gravitationally bound object with a radius r ≤ 2GM/c2, which occurs in the non-singular version of the nonsymmetric gravitational theory (NGT), replaces the black hole in Einstein gravity theory. This object is kept stable by the attractive and repulsive forces generated by NGT, as well as standard matter pressures, and is called a superdense object (SDO). The luminosity of gravitational waves emitted by a SDO with a red-shift of order unity is calculated and it is found that it could be a strong source of gravitational radiation at low frequencies. The active galactic nucleus of M87 is identified with a SDO and the recent observational results obtained by the Hubble Space Telesope are used to estimate the amplitude of gravitational radiation.
