Relativistic jets from Active Galactic Nuclei (AGN) are suggested to originate from supermassive black holes at the center of galaxies, surrounded by their accretion disks. The properties of the disks are intrinsically linked to the characteristics of the launched jets, in what is known as disk-jet connection. When considering their magnetization, accretion disks fall into two main categories: the low-magnetized Standard and Normal Evolution (SANE) disks, and the highly-magnetized Magnetically Arrested Disks (MAD). These distinct disk classes result in different magnetic fields within the jets, impacting observational signatures such as their acceleration, collimation, and polarization. These phenomena can be probed by means of cm-/mm-Very Long Baseline Interferometry (VLBI) observations. Through the characterization of the mentioned observational jet properties, we can employ theoretical models to constrain the magnetization of the jets and, correspondingly, their accretion disks. This poster will present our recent results on the disk-jet connection with a focus on the nearby jetted radio galaxy NGC315. For the latter, we are able to suggest the presence of a MAD starting from the physical properties of its sub-parsec, parsec scales jet inferred from a multi-frequency VLBI dataset.
