Gravitational wave signature of a mini creation event (MCE)

TL;DR

This paper proposes the mini creation event (MCE) as a new astrophysical source of gravitational waves, potentially detectable by advanced LIGO, especially within the quasi steady state cosmology framework.

Contribution

It introduces the MCE as a novel gravitational wave source and computes its waveform, demonstrating its detectability with current gravitational wave detectors.

Findings

MCE signals can produce high enough SNR for detection by aLIGO.

MCE waveform signatures are distinct and detectable with matched filtering.

Supports MCE as a viable gravitational wave source in non-standard cosmology.

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.
