We explore the possibility of jet collisions with accreting tori orbitingaround SMBHs. The analysis provides constraints on formation and theobservational evidences of the host configurations. We use a GRHD model,investigating the light surfaces contraints in aggregates of misaligned toriorbiting a central static Schwarzschild black hole. Each (toroidal)configuration of the agglomeration is a geometrically thick, pressuresupported, perfect fluid torus. Aggregates include proto-jets, the open cuspedsolutions associated to the geometrically thick tori. Collision emergence andthe stability properties of the aggregates are considered at differentinclination angles relative to a fixed distant observer. We relate theconstraints to the relevant frequencies of the configurations and fluidspecific angular momentum, separating the constraints related to the fluidshydrodynamics and to the geometric backgrounds. We analyze existence ofaccreting tori supporting jet-emission. We discuss the existence oforbit-replicas that could host shadowing effects in replicas of the emissionsin two regions, close and far from the BH (horizon replicas in jet shells). Theinvestigation clarifies the role of the pressure gradients of the orbitingmatter and the essential role of the radial gradient of the pressure in thedetermination of the disk verticality. Finally we analyze the possibility thata toroidal magnetic field could be related to the collimation of proto-jets.
