Gravitational wave signature of a mini creation event (MCE)

Abstract

In light of the recent discoveries of binary black hole events by the LIGO detectors, we propose a new astrophysical source, namely, the mini creation event (MCE) as a possible source of gravitational waves (GW) to be detected by LIGO. The MCE is at the heart of the quasi steady state cosmology (QSSC) and is not expected to occur in standard cosmology. Generically, the MCE is anisotropic and we assume a Bianchi Tpye I model for its description. We compute its signature waveform and assume masses, distances analogous to the events detected by LIGO. By matched filtering the signal we find that, for a broad range of model parameters, the signal to noise ratio of the randomly oriented MCE is sufficiently high for a confident detection by advanced LIGO (aLIGO).We therefore propose the MCE as a viable astrophyical source of GW.
