abstract
We present new cosmological parameter constraints for general Horndeski scalar-tensor theories, using CMB, redshift space distortion, matter power spectrum and BAO measurements from the Planck, SDSS/BOSS and 6dF surveys. We focus on theories with cosmological gravitational waves propagating at the speed of light, $c_{\rm GW} = c$, implementing and discussing several previously unaccounted for aspects in the constraint derivation for such theories, that qualitatively affect the resulting constraints. In order to ensure our conclusions are robust, we compare results for three different parametrisations of the free functions in Horndeski scalar-tensor theories, identifying several parametrisation-independent features of the constraints. We also consider models, where $c_{\rm GW} \neq c$ in cosmological settings (still allowed after GW170817 for frequency-dependent $c_{\rm GW}$) and show how this affects cosmological parameter constraints.

How deep can a cosmic void be? Voids-informed theoretical bounds in Galileon gravity
Galileon models must obey a void-depth limit tied to expansion history to avoid force breakdowns, excluding ~60% of a linear parameterization's space by z less than or equal to 10.

Radio sirens: inferring $H_0$ with binary black holes and neutral hydrogen in the era of the Einstein Telescope and the SKA Observatory
Using simulated binary black hole mergers and neutral hydrogen maps, the radio sirens method constrains H0 to 8% precision with 3000 high-SNR events, offering a 90% improvement over standard dark siren analyses.

Cosmological tensions in Proca-Nuevo theory
Fitting a one-parameter vector-tensor dark energy model to CMB, BAO, and supernova data reduces the Hubble tension to about 1.5–2σ, but the preference over ΛCDM is weak and disappears once full perturbations are included.

A Bright Future? Prospects for Cosmological Tests of GR with Multimessenger Gravitational Wave Events
Simulated bright siren events show LVK-era detections will not competitively constrain Horndeski gravity parameters, while one year of Einstein Telescope observations could detect αM ≠ 0 at over 3σ.

Constraining dark energy with complementary probes of large-scale structure
Adding DESI DR1 RSD, DES Y3 3x2pt, and ISW cross-correlations to CMB+BAO+SNe improves FoM for EFTofDE parameters {cB, cM} by 2.69x and for {mu(z), Sigma(z)} by 3.37x, with 2.9 sigma deviation from LambdaCDM similar to...
