Description
Among the various sources, the hot plasma in the early universe is quite interesting since it produces the Cosmic Gravitational Cosmic Microwave (CGMB) signal. Lambda CDM gives quite small value to be detected from the present technology based detectors. We show that the higher curvature term can enhance the signal. To be specific, the Einstein-dilaton-Gauss-Bonnet (EdGB) Gravity, one of the simplest extensions of Einstein's gravity with the higher curvature term, will be considered. We briefly mention, Unlike Einstein's gravity, there exists a minimum mass below which the black hole cannot be formed. EdGB cosmology will be shown to have the new phases at high temperature. Among many phenomena applicable we show the enhance the Cosmic Gravitational Cosmic Microwave (CGMB) signal, which can be used to constrain the theory.
