GW250114 data confirm the remnant is consistent with a Kerr black hole and bound the dominant quadrupolar mode frequency to within a few percent of the GR prediction, with constraints tighter than prior multi-event catalogs.

Thermal aberrations induce low-pass frequency dynamics for quadratic wavefront mismatches and high-pass dynamics for higher-order aberrations, degrading squeezed states differently in current versus future gravitational wave detectors.
Extends prior two-photon formalism to compute true motion and optimal cooling in multi-DOF GW detector test masses, finding sub-unity occupation numbers possible over the oscillator bandwidth for common definitions.
