(maximum 200 words) Direct detection of a stochastic gravitational wave background (SGWB) of primordial origin would be a profound discovery, providing deep insight into new physics. A variety of early Universe scenarios – including inflation, phase transitions, and topological defects – predict the production of a SGWB. Many of these scenarios are within reach of current and/or planned GW detectors. Measurement of the spectrum, polarization, and anisotropies can help identify the energy scale… Expand


Using a Primordial Gravitational Wave Background to Illuminate New Physics
A primordial spectrum of gravitational waves serves as a backlight to the relativistic degrees of freedom of the cosmological fluid. Any change in the particle physics content, due to a change ofExpand

Probing the pre-BBN universe with gravitational waves from cosmic strings
A bstractMany motivated extensions of the Standard Model predict the existence of cosmic strings. Gravitational waves originating from the dynamics of the resulting cosmic string network have theExpand
Gravitational-wave cosmology across 29 decades in frequency
Quantum fluctuations of the gravitational field in the early Universe, amplified by inflation, produce a primordial gravitational-wave background across a broad frequency band. We derive constraintsExpand
Cosmic archaeology with gravitational waves from cosmic strings
Cosmic strings are generic cosmological predictions of many extensions of the Standard Model of particle physics, such as a $U(1)^\prime$ symmetry breaking phase transition in the early universe orExpand
Stochastic background of gravitational waves from hybrid preheating.
The power spectrum of the stochastic background of gravitational waves produced at reheating after hybrid inflation is studied and it is found that the amplitude could be significant for high-scale models, although the typical frequencies are well beyond what could be reached by planned gravitational wave observatories.

Gravitational waves from the fragmentation of a supersymmetric condensate
We discuss the production of gravity waves from the fragmentation of a supersymmetric condensate in the early universe. Supersymmetry predicts the existence of flat directions in the potential. AtExpand
Primordial Anisotropies in the Gravitational Wave Background from Cosmological Phase Transitions.
Correlations within the gravitational wave anisotropies and their cross-correlations with the CMB can provide new insights into the mechanism underlying primordial fluctuations, such as multifield inflation, as well as reveal the existence of nonstandard "hidden sectors" of particle physics in earlier eras.

Astrophysics and cosmology with a decihertz gravitational-wave detector: TianGO
We present the astrophysical science case for a space-based, decihertz gravitational-wave (GW) detector. We particularly highlight an ability to infer a source’s sky location, both when combined withExpand
