Relativistic jets from supermassive black holes (SMBHs) are vital drivers of massive galaxy properties, and cosmic rays
(CRs) within SMBH jets have shown to be a key ingredient in the process. It is therefore crucial to model the effects of
CRs self-consistently in numerical simulations. In this talk, I will present how we could apply 3D CR-
magnetohydrodynamic (MHD) simulations to understand enigmatic phenomena in the Universe, including the Fermi
bubbles within the Milky Way Galaxy, as well as the newly discovered odd radio circles (ORCs). Our investigations
suggest that both phenomena could be explained by powerful jet activity of SMBHs.
