DESCRIPTION:While several promising candidate supermassive black hole bina
 ries have been identified\, more realistic physical modeling of these syst
 ems will be necessary to confirm their identity and perform robust searche
 s in the era of big-data astronomy. Unfortunately\, the large range of tem
 poral and physical scales and wide parameter space have historically made 
 their modeling prohibitive when performed via full 3D general relativistic
  magnetohydrodynamic simulations (3D-GRMHD). I will first demonstrate the 
 necessity of this type of modeling\, despite its complexity and computatio
 nal expense\, and then briefly describe a new tool we have built to aid in
  the effort. I will present our recent 3D-GRMHD simulations which extend l
 onger in duration than comparable prior models and achieve higher resoluti
 on and global realism\, made possible by using our new multi-domain/multi-
 physics code\, PatchworkMHD. With these improvements we have found unexpec
 ted 3D hydrodynamical and magnetic behavior that is guiding us towards uni
 que binary observational signatures. In upcoming surveys like Vera Rubin O
 bservatory’s LSST these unique signatures will be key to confirming the 
 identity of binary black hole systems and secure them as a corner-stone of
  multi-messenger astrophysics.
