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.
Tidal stripping fails to explain missing bright red giants near Sgr A* as loss-cone diffusion scales too weakly with stellar radius compared to the rapid drop in red-giant lifetimes.
