  "abstract": "Relativistic jets launched by active galactic nuclei are fundamental for understanding the physics of accreting supermassive black holes and their immediate environments, but the origin of these jets remains an open question. The relativistic jet of blazar NRAO 150 has complex morphology that evolves on short timescales because the projection effects are strong. This enabled us to perform a detailed kinematic analysis. We used data by the Very Long Baseline Array and the European Very Long Baseline Interferometry Network from 2010 until 2019 at 43 GHz to understand the formation and launching processes of the jet in NRAO 150. We studied the γ -ray and radio light curves together with total intensity and linear polarisation information to probe the connection between flaring events, γ -ray emission, and the ejection of new jet features. Furthermore, we investigated the magnetic field configuration in the innermost jet region as captured in polarised light to gain insights about its configuration before, during, and after a γ -ray flare. Our results indicate a close temporal link between the γ -ray flaring activity and the ejection of new very long baseline interferometry ( VLBI) jet components, suggesting that the high-energy emission is produced downstream of the VLBI core. The combined kinematic and polarimetric evidence further indicates a toroidal magnetic field in the inner jet. This highlights the key role of magnetic fields in governing the jet dynamics and high-energy emission in NRAO 150.",
