abstract
It is suggested, by using a covariant lagrangian formalism to estimate the equation of state $w = p/\rho$, that stringy dark energy predicts $w < -1$, a negative pressure larger in magnitude than that for a cosmological constant or quintessence. This would lead to a later transition from decelerating to accelerating cosmological expansion; $w = - 4/3$ is briefly considered as one illustrative example.

Multi-Messenger Cosmology: A Route to Accurate Inference of Dark Energy Beyond CPL Parametrization from XG Detectors
A simulation forecast claims CE+ET bright standard sirens can measure dark energy EoS parameters with sigma(w0)=0.010, sigma(wa)=0.049, sigma(wb)=0.072, better than other planned probes.

Quintom Model Perturbations
A two-field quintom model reproduces w0waCDM perturbation features and is mildly favored over it in Bayesian fits to BAO, CMB, and SNIa data.
