DESCRIPTION:Speakers: DEBBRECHT\, Lena ()\nNRAO 150 is a prominent radio t
 o millimetre emitting quasar at redshift $z=1.52$. \nThis source exhibits 
 a particularly intriguing structure\, as the jet is seen at an extremely s
 mall angle to the line of sight. \nPrevious Very Long Baseline Interferome
 try (VLBI) observations have revealed a fast counter-clockwise rotation of
  its innermost jet region. \nOwing to the high angular resolution provided
  by VLBI\, we can probe relativistic jets at such small scales\, in the vi
 cinity of the central engine. \nIn this work\, we aim to study the morphol
 ogy and kinematic behaviour of the jet of NRAO 150.\nThe source was observ
 ed by the Global Millimeter VLBI Array (GMVA) at 86 GHz\, and by the Europ
 ean VLBI Network (EVN) at 43 GHz and 22 GHz. The data was imaged in total 
 intensity and geometric model fitting was applied\, in order to perform a 
 comprehensive analysis of the jet structure. \nWe report a counter-clockwi
 se jet rotation for one emission feature\, which is consistent with previo
 us VLBI studies. \nWe also present a new kinematic model for this source a
 nd fit a helical model to the component's trajectory. The fit supports the
  assumption of a counter-clockwise jet rotation. \nGeometric projection ef
 fects also need to be taken into account\, as the source points at a small
  angle to our line of sight. \nIn this talk we will examine and discuss po
 ssible scenarios for these projection effects and interpret how they relat
 e to the observed jet features.\n\nhttps://events.mpifr-bonn.mpg.de/indico
