Observational prospects for phase transitions at LISA: Fisher matrix analysis

Chloe Gowling et al.

Summary: This study investigates LISA's sensitivity to the thermodynamic parameters encoded in the stochastic background produced by a phase transition using the sound shell model to characterize the gravitational wave power spectrum and the Fisher matrix to estimate uncertainties. The power spectrum in the sound shell model can be well approximated by a four-parameter double broken power law, and the peak power and frequency can be measured to approximately 10% accuracy for signal-to-noise ratios (SNRs) above 20. The phase boundary speed is found to be the best constrained parameter, with potential for good prospects in combinations of parameters.

Model-independent energy budget for LISA

Felix Giese et al.

Summary: The study presents a simple method to obtain the kinetic energy fraction in gravitational waves generated during a cosmological first-order phase transition based on wall velocity and quantities from the particle physics model at the nucleation temperature. The study compares results for deflagrations and hybrids, provides a Python code snippet for calculating the kinetic energy fraction, and evaluates realistic deviations in speed of sound close to the phase transition temperature in a specific model.

Improved reconstruction of a stochastic gravitational wave background with LISA

Raphael Flauger et al.

Summary: A data analysis methodology was proposed for model-independent reconstruction of the spectral shape of a stochastic gravitational wave background with LISA; The improved algorithm includes a complete set of TDI channels, reducing uncertainties, avoiding local extrema in likelihood maximization, and breaking degeneracies between signal and instrumental noise; Testing with case studies showed that additional channels are helpful in various ways for the reconstruction process.

A hybrid simulation of gravitational wave production in first-order phase transitions

Ryusuke Jinno et al.

Summary: The LISA telescope will provide the opportunity to explore a first-order phase transition near the electroweak scale. Current estimates of the gravitational wave spectrum are based on numerical simulations or analytical approximations. This work presents a novel method to calculate the GW spectra from sound waves, which does not require resolving the scale of bubble wall thickness, making the simulations more economical.
