Searching for cross-correlation between stochastic gravitational-wave background and galaxy number counts

Kate Z. Yang et al.

Summary: The study investigated the correlation between the SGWB map and electromagnetic tracers in the Universe to improve sensitivity in detecting anisotropy in the SGWB. Results showed that the coherence between the SGWB and galaxy number count maps is mainly due to null measurement noise in the SGWB maps, and therefore not statistically significant. Future analysis using more sensitive upcoming SGWB measurements is expected to provide improved results.

Stochastic gravitational-wave background in quantum gravity

Gianluca Calcagni et al.

Summary: Among the five cosmological quantum-gravity or quantum-gravity-inspired scenarios explored, only the non-local quantum gravity model is found to be unobservable, while the other models can achieve the strain sensitivity of DECIGO but not that of LIGO-Virgo-KAGRA, LISA or Einstein Telescope. Models with red-tilted spectra or exceptionally tiny quantum corrections are also found to be non-detectable.

Cross-Correlating Astrophysical and Cosmological Gravitational Wave Backgrounds with the Cosmic Microwave Background

A. Ricciardone et al.

Summary: General relativity offers a powerful tool to extract both astrophysical and cosmological information from stochastic gravitational-wave backgrounds by cross-correlation with other cosmological tracers. Future GW detectors like LISA or BBO are capable of measuring such cross-correlation signals. Additionally, constrained realization maps of SGWBs extracted from high-resolution CMB Planck maps provide a new tool for faithfully reconstructing the expected SGWB map in the low-noise regime.

Cross-correlations as a diagnostic tool for primordial gravitational waves

Ameek Malhotra et al.

Summary: The study explores and confirms the effectiveness of cross-correlating stochastic gravitational wave background anisotropies with CMB temperature fluctuations to establish the primordial nature of a given gravitational wave signal. It considers gravitational wave anisotropies induced by scalar-tensor-tensor primordial non-Gaussianity and calculates the expected uncertainty on the non-linearity parameter F-NL for various proposed experiments. Additionally, it calculates the theoretical, cosmic-variance-limited, error on the non-linearity parameter as a benchmark for future survey planning.

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.

Spectral separation of the stochastic gravitational-wave background for LISA: Observing both cosmological and astrophysical backgrounds

Guillaume Boileau et al.

Summary: This study aims to observe a stochastic gravitational-wave background with LISA, emphasizing the importance of spectral separability between cosmological and astrophysical backgrounds. Using adaptive Markov chain Monte Carlo methods, the detectable limits for future LISA measurements of SGWB are estimated, along with calculating the Cramer-Rao lower bound. Based on the expected astrophysical background level, LISA can detect a specific cosmological SGWB energy density after 4 years of observation.

Detecting dark energy fluctuations with gravitational waves

Alice Garoffolo et al.

Summary: In models of dynamical dark energy and gravity beyond the standard cosmological scenario, estimates of luminosity distance from electromagnetic and gravitational wave sources differ, leaving a unique imprint on the angular power-spectrum of fluctuations. By exploiting the synergy in supernovae and gravitational wave distance measurements, a joint estimator has been constructed to directly probe dark energy fluctuations, providing conclusive evidence for their existence. Additionally, this measurement can also allow for probing the running of the Planck mass, with experimental requirements discussed for detecting these signals.

Early modified gravity in light of the H0 tension and LSS data

Matteo Braglia et al.

Summary: The early modified gravity model proposed involves a scalar field with nonminimal coupling to the Ricci curvature, showing potential in alleviating the H-0 tension while fitting well with CMB anisotropies and BAO data. The scalar field in the model remains frozen in the radiation era, growing near matter-radiation equality and dampening into coherent oscillations due to a small effective mass induced by a quartic potential, ultimately leading to weaker gravitational strength at early times. Comparative analysis with other models suggests that this EMG model can significantly alleviate the H-0 tension when considering the full shape of the matter power spectrum in addition to CMB and SN data.
