Data pubblicazione: | 2018 | Rivista: | THE ASTROPHYSICAL JOURNAL | Numero: | 864 | Fascicolo: | 2 | Da pagina:: | 118 | Abstract: | Radio jets in active galaxies have been expected to interact with circumnuclear environments in their early phase evolutions. By performing the multi-epoch monitoring observation with the KVN and VERA Array at 43 GHz, we investigate the kinematics of the notable newborn bright component C3 located at the tip of the recurrent jet of 3C 84. During 2015 August-September, we discover the flip of C3 and the amount of the flip is about 0.4 mas in angular scale, which corresponds to 0.14 parsec in physical scale. After the flip of C3, it wobbled at the same location for a few months and then it restarted to propagate toward the southern direction. The flux density of C3 coherently showed the monotonic increase during the observation period. The flip is in good agreement with hydrodynamical simulations of jets in clumpy ambient medium. We estimate the number density of the putative clump based on the momentum balance between the jet thrust and the ram pressure from the clump and it is about 10<SUP>3-5</SUP> cm<SUP>-3</SUP>. We briefly discuss possible origins of the clump. | URI: | http://hdl.handle.net/20.500.12386/28041 | URL: | https://iopscience.iop.org/article/10.3847/1538-4357/aad6e3 | ISSN: | 0004-637X | DOI: | 10.3847/1538-4357/aad6e3 | Bibcode ADS: | 2018ApJ...864..118K | Fulltext: | open |
