Continuous spin gravity yields GW time-delay deviations of order ρ_g/ω from GR predictions for frequencies above ρ_g, with damping below, enabling sensitivity to spin scales ~10^{-14} eV at ground interferometers and ~10^{-24} eV at PTAs.
FABLE simulation predictions for the nanohertz gravitational wave background are statistically consistent with NANOGrav 15-year data at 1–2.5σ tension, with physically motivated population modifications further improving agreement.
SKAO timing of a handful of binary pulsars can reach unprecedented sensitivity to microhertz gravitational waves from inspiralling massive black hole binaries via resonant perturbations.
Proposes and simulates the use of space-based atomic clock networks for one-way Doppler tracking of gravitational waves in concert with LISA, including noise analysis and preliminary parameter estimation on binary sources.
A perturbative analytical model of gravitational waves on an exact Bianchi IV background is derived via the proper-time method and shown to be stable.
Reports timing solutions and basic properties for 49 pulsars (18 new) from the AO327 survey, with emission feature notes and model comparisons for distances.
VLBI astrometry of nearby MSPs can supply the distance priors needed to localize individual continuous-wave nanohertz GW sources to ~10^{-3} deg².
Simulations forecast 21-51% probability of resolving individual SMBH binaries with PTAs in 0-10 years, with localization areas containing ~190k early-type galaxies on average and a ranking method that excludes roughly half the candidates when galaxy properties are available.
SKAO forecasts show that planned observations will improve SGWB anisotropy constraints but remain insufficient to detect the kinematic dipole even in joint PTA-astrometry analyses.
A review summarizing detection methods, population statistics, and coevolution of supermassive black holes with host galaxies from early universe observations and simulations.
