On searches for gravitational waves from mini creation event by laser interferometric detectors

TL;DR

This paper investigates the potential detection of gravitational waves from mini creation events, as predicted by quasi-steady state cosmology, using laser interferometric detectors like LIGO and LISA.

Contribution

It models gravitational waveforms from mini creation events with linear jets and estimates detector responses, exploring an alternative cosmological source of gravitational waves.

Findings

Gravitational waves from mini creation events are theoretically detectable.

Response estimates for LIGO and LISA are provided.

Mini creation events could be a new source for gravitational wave astronomy.

Abstract

As an alternative view to the standard big bang cosmology the quasi-steady state cosmology(QSSC) argues that the universe was not created in a single great explosion; it neither had a beginning nor will it ever come to an end. The creation of new matter in the universe is a regular feature occurring through finite explosive events. Each creation event is called a mini-bang or, a mini creation event(MCE). Gravitational waves are expected to be generated due to any anisotropy present in this process of creation. Mini creation event ejecting matter in two oppositely directed jets is thus a source of gravitational waves which can in principle be detected by laser interferometric detectors. In the present work we consider the gravitational waveforms propagated by linear jets and then estimate the response of laser interferometric detectors like LIGO and LISA.
