Gravitational waves from melting cosmic strings

William T. Emond et al.

Summary: The appearance of cosmic strings is a common phenomenon in the early Universe, usually associated with high energy scales. This paper discusses a different scenario where the formation of cosmic strings is approximately scale free. The dynamics of these melting strings in an expanding Universe is equivalent to that of constant tension strings in a Minkowski spacetime, and the resulting spectrum of gravitational waves from string loops is non-flat and exhibits a characteristic falloff at frequencies below the peak one.

Gravitational shine of dark domain walls

E. Babichev et al.

Summary: Cosmic domain walls are harmless if their tension decreases with the expansion of the Universe. The tension can be large in the early Universe without conflicting observations if it is induced dynamically through interaction with hot primordial plasma. These topological defects can serve as a powerful source of gravitational waves due to their large initial tension.

Primordial gravitational waves from excited states

Jacopo Fumagalli et al.

Summary: It has been shown that a scalar excited state with large occupation numbers during inflation can lead to an enhancement of tensor modes and a characteristic pattern of order-one oscillations in the associated stochastic gravitational wave background. Additionally, an effective excited state may emerge dynamically as a result of a transient non-adiabatic evolution, such as a sharp feature along the inflationary history.

Searching for a subpopulation of primordial black holes in LIGO-Virgo

Gabriele Franciolini et al.

Summary: This study performs a hierarchical Bayesian analysis using the GWTC-2 catalog to constrain the fraction of primordial black holes (PBHs) in the data. Different astrophysical models are taken into account, and it is found that the fraction of PBHs varies significantly depending on the assumed models. The contribution from the stable-mass-transfer isolated formation channel reduces the need for PBHs, except in explaining mass-gap events.

Beyond freeze-in: Dark matter via inverse phase transition and gravitational wave signal

S. Ramazanov et al.

Summary: This study proposes a novel scenario for the production of dark matter that is naturally connected with the generation of gravitational waves. The model describes dark matter as a real scalar that interacts with the hot primordial plasma through a coupling to another scalar field. The model predicts the formation of domain walls in the Universe, which emit gravitational waves with characteristics determined by those of dark matter.

Non-Gaussianity and the induced gravitational wave background

Peter Adshead et al.

Summary: We studied the impact of scalar metric fluctuations on the generation of gravitational waves, emphasizing the role of primordial non-Gaussianity, especially the disconnected and connected components of the primordial trispectrum.

Probing primordial features with the stochastic gravitational wave background

Matteo Braglia et al.

Summary: The stochastic gravitational wave background provides an opportunity to observe signals of primordial features from inflationary models. The study focuses on the detectability of these signals with future space-based gravitational waves experiments within the LISA mission's frequency range. Two approaches of signal reconstruction and template application for data analysis are discussed to connect with future experimental data.

Constraints on primordial black holes

Bernard Carr et al.

Summary: In this article, constraints on the fraction of the Universe that may have gone into primordial black holes (PBHs) over a range of masses are updated. The discussion covers the reasons why PBHs smaller than a certain mass threshold are constrained and the various constraints on PBHs larger than that threshold.

Scalar Induced Gravitational Waves Review

Guillem Domenech

Summary: This review provides an overview of gravitational waves induced by primordial fluctuations, focusing on the intuitive physics and general analytical formulation behind induced gravitational waves. It suggests the open possibility of a different expansion history in the primordial universe than the commonly assumed radiation dominated cosmology, and aims to raise awareness of current advances in the cosmology of induced gravitational waves.

Induced gravitational waves as a cosmological probe of the sound speed during the QCD phase transition

Katsuya T. Abe et al.

Summary: The paper investigates the measurement of the equation of state parameter w and the sound speed c(s) of the phase transition plasma using gravitational waves. The study reveals the predicted spectrum of induced gravitational waves and their potential in indirectly probing w and c(s) through the dynamics of primordial perturbations. The results show that the amplitude of primordial scalar power in a specific range can be consistent with current observational constraints and detectable in future observations.

Resonant features in the stochastic gravitational wave background

Jacopo Fumagalli et al.

Summary: This study examines the post-inflationary contribution of a resonant feature in the scalar power spectrum to the stochastic gravitational wave background, finding that oscillations lead to a modulation in the gravitational wave spectrum. The results can serve as templates for future data signal reconstruction and allow for extracting information about the small scale scalar power spectrum from measurements of the stochastic gravitational wave background.

Oscillations in the stochastic gravitational wave background from sharp features and particle production during inflation

Jacopo Fumagalli et al.

Summary: We have identified a characteristic pattern in the scalar-induced stochastic gravitational wave background generated during inflation, showing periodic oscillations in the scalar power spectrum and resulting in modulations in the gravitational wave energy density spectrum. By analyzing the induced spectrum of gravitational waves and presenting a concrete realization in the framework of multifield inflation, we propose that this stochastic background could potentially be detected in future gravitational wave observatories. This work motivates further research on linking primordial features to observable properties of the stochastic gravitational wave background and developing data analysis techniques for their detection.

Probing non-Gaussianities with the high frequency tail of induced gravitational waves

Vicente Atal et al.

Summary: In this study, we explore the spectrum of gravitational waves induced by a peaked primordial curvature power spectrum from single-field inflationary models. We suggest that the f(NL) parameter can be determined by measuring the high frequency spectral tilt of induced gravitational waves. It is found that the non-Gaussian impact of f(NL) on Omega(GW) is to broaden its peak, albeit at a negligible level to avoid overproducing primordial black holes. We also discuss potential degeneracies in the high frequency spectral tilt between f(NL) and the universe's general equation of state w. Finally, constraints on the amplitude, peak, and slope of the primordial power spectrum are discussed in relation to current and future gravitational wave experiments combined with limits on mu distortions from the cosmic microwave background.

A topic review on probing primordial black hole dark matter with scalar induced gravitational waves

Chen Yuan et al.

Summary: PBHs may be formed from the collapse of over-densities generated by large scalar curvature perturbations in the radiation dominated era. Interest in PBH DM has been aroused recently due to their potential role in explaining the merger events of binary black holes discovered by LIGO/VIRGO. The study mainly focuses on the physics of scalar induced gravitational waves accompanying the formation of PBH DM.

Spectrum oscillations from features in the potential of single-field inflation

I Dalianis et al.

Summary: The study investigates the impact of steep steplike features in the potential on the power spectrum of curvature perturbations in single-field inflationary models. It is found that these features can enhance the strength of curvature perturbations and generate distinct oscillatory patterns. The oscillatory characteristics are influenced by the number and position of features in the potential, which could potentially be detected by future space interferometers.

Summary: In this study, the spectral shapes of gravitational waves induced by scalar perturbations in the early Universe are explored, and their ability to constrain and discriminate among inflationary models is demonstrated. The production of gravitational waves during kination and radiation eras can be distinguished by their spectral shapes and amplitudes.
