چکیده
The production of primordial black hole (PBH) dark matter (DM) and the generation scalar induced secondary gravitational waves by using enhancement mechanism with a peak function in non-canonical kinetic term S-dual inflation is discussed. We show explicitly that power spectrum for curvature perturbation can be enhanced at 10<sup>12</sup>Mpc<sup>-1</sup>, 10<sup>8</sup>Mpc<sup>-1</sup> 10<sup>5</sup>Mpc<sup>-1</sup>, masses around 10<sup>-13</sup> solar mass, Earth's mass stellar frequencies mHz, μHz nHz, respectively. holes scale make up almost all associated testable spaced based wave observatory. amplitude perturbations small scales become large term. apply to produce abundant PBHs observable (SIGWs). consistent observational constraint order 0.01. Either sharp or broad possible different shapes choosing values q. By adjusting position <i>ϕ<sub>p</sub></i> function, scales, henceforth SIGWs frequencies, are produced. choose three get PBH DM Earth’s µHz nHz. may explain observed LIGO/Virgo collaboration, earth-mass planet 9. matter. frequency nHz PTA observations, mHz space GW results works inflation.

Primordial Gravitational Waves From Open Inflation
We calculate the spectrum of gravitational waves generated during inflation in open (Ω0 < 1) inflationary models. In such models an initial epoch of old inflation solves the horizon and flatness problems, and during this first epoch of inflation the quantum state of the graviton field rapidly approaches the Bunch-Davies vacuum. Then old inflation ends by the nucleation of a single bubble, insid...
متن کاملGravitational waves from inspiraling binary black holes
Binary black holes are the most promising candidate sources for the first generation of earth-based interferometric gravitational-wave detectors. We summarize and discuss the state-of-the-art analytic techniques developed during the last years to better describe the late dynamical evolution of binary black holes of comparable masses.

متن کاملMassive Primordial Black Holes in Hybrid Inflation
It is well known that energy density fluctuations at the early Universe give rise primordial black holes (BH) formation [1]. Widespread opinion is that these BHs are small enough with masses somewhere in the range MBH ∼ 10−5 − 10gram depending on specific model. What could be said about BHs with masses in the range 10 − 10gram? There exist a few number of inflationary models that predict BH pro...
متن کاملGravitational waves versus black holes
It is argued that, in order for the gravitational field to be propagated as a wave, it is necessary for it to satisfy a further set of field equations, in addition to those of Einstein and Hilbert, and these equations mean there is a preferred coordinate frame, called the Global Inertial Frame, giving rise to a unique metric . The implication is that a true gravitational field is not compatible...
متن کاملGravitational Waves from Inflation
Gravitational waves (GW) are tensor perturbations of the metric of curved spacetime that propagate. The metric g is a matrix (or differential 2-form, to be specific) that fully describes the 4-dimensional manifold of a spacetime in general relativity. The components of the full metric gμν are the sum of an unperturbed metric and the perturbation hμν , which varies on a smaller scale (separated ...
