Radiative barriers in SUSY flat directions enable supercooled PTs yielding Ω_GW h² up to ~3e-10 for M_λ̃/v_X in 0.05-0.23, with the hidden sector also reproducing Ω_CDM h²=0.12 for m_q ~30-800 keV.
Horizon-AGN shows galaxy and black hole merger rates both rise with stellar mass and fall with redshift, peaking near z=2-3, establishing a direct evolutionary link from galaxy interactions to black hole coalescences.
A statistically significant positive correlation (r ~ 0.12-0.13) exists between the absolute velocity offset of broad Hβ lines and dust reddening in quasars, consistent with a population of recoiling black holes.
Next-generation IFU instruments could detect core scouring and tangential anisotropy from MBH binaries up to z~0.14 for ~150 pc cores and higher redshifts for larger cores, expanding searchable volume by 30-40 times including lower-mass systems.
Bayesian fitting of an eccentric Keplerian orbit to the radio light curve of PKS 2131-021 gives e = 0.053 ± 0.015 without red noise but favors a circular orbit plus DRW noise with e < 0.15.
The shadow of a Kerr-Newman-like black hole in Bumblebee gravity with plasma is analyzed via observables and constrained by M87* EHT data, with spin and Lorentz violation mainly distorting the shape while charge and plasma shrink the size.
Weak lensing surveys cannot detect nanohertz-microhertz gravitational waves from supermassive black hole binaries under realistic conditions; only unattainable idealized surveys could probe this band.
