Primordial gravitational waves are expected to create a stochastic background encoding information about the early Universe that may not be accessible by other means. However, the primordial background is obscured by an astrophysical foreground consisting of gravitational waves from compact binaries. We demonstrate a Bayesian method for estimating the primordial background in the presence of an astrophysical foreground. Since the background and foreground signal parameters are estimated…

Simultaneous estimation of astrophysical and cosmological stochastic gravitational-wave backgrounds with terrestrial detectors
The recent Advanced LIGO and Advanced Virgo joint observing runs have not claimed a stochastic gravitational-wave background detection, but one expects this to change as the sensitivity of the
Spectral separation of the stochastic gravitational-wave background for LISA: Observing both cosmological and astrophysical backgrounds
With the goal of attempting to observe a stochastic gravitational wave background (SGWB) with LISA, the spectral separability of the cosmological and astrophysical backgrounds is important to
Cross-correlations as a diagnostic tool for primordial gravitational waves
We explore and corroborate, by working out explicit examples, the effectiveness of cross-correlating stochastic gravitational wave background anisotropies with CMB temperature fluctuations as a way
Multifrequency Gravitational Wave Background From Continuous Sources
Gravitational waves have been detected in the past few years from several transient events such as merging stellar mass black holes, binary neutron stars, etc. These waves have frequencies in a band
Frequentist versus Bayesian analyses: Cross-correlation as an approximate sufficient statistic for LIGO-Virgo stochastic background searches
This work shows that the frequency integrand of the cross-correlation statistic and its variance are approximate sufficient statistics for ground-based searches for stochastic gravitational-wave backgrounds and closes a gap in the LIGO-Virgo literature.
Probing parity-odd bispectra with anisotropies of GW $V$ modes
It is well known that non-trivial squeezed tensor bispectra can lead to anisotropies in the inflationary stochastic gravitational wave (GW) background, providing us with an alternative and

Stochastic Gravitational-Wave Backgrounds: Current Detection Efforts and Future Prospects
The collection of individually resolvable gravitational wave (GW) events makes up a tiny fraction of all GW signals that reach our detectors, while most lie below the confusion limit and are
Testing the early universe with anisotropies of the gravitational wave background
In this work we analyse in detail the possibility of using small and intermediate-scale gravitational wave anisotropies to constrain the inflationary particle content. First, we develop a
Gravitational Waves from the Cosmological Quark-Hadron Phase Transition Revisited
The recent claim by the NANOGrav collaboration of a possible detection of an isotropic gravitational wave background stimulated a series of investigations searching for the origin of such a signal.

Digging Deeper: Observing Primordial Gravitational Waves below the Binary-Black-Hole-Produced Stochastic Background.
It is demonstrated that the next generation of ground-based detectors will be able to observe binary black hole mergers throughout the Universe with sufficient efficiency that the confusion background can potentially be subtracted to observe the primordial background at the level of Ω_{GW}≃10^{-13} after 5 years of observation.

Parameter estimation in searches for the stochastic gravitational-wave background.
A Bayesian framework is presented for estimating the parameters associated with different SGWB models using data from gravitational-wave detectors and this technique is applied to recent results from LIGO to produce the first simultaneous 95% confidence level limits on multiple parameters in generic power-law SG WB models and inSGWB models of compact binary coalescences.
