A Distinctive Disk-Jet Coupling in the Seyfert-1 Active Galactic Nucleus NGC 4051

摘要: We report on the results of a simultaneous monitoring campaign employing eight Chandra X-ray (0.5–10 keV) and six Very Large Array/Extended Array (8.4 GHz) radio observations NGC 4051 over seven months. Evidence for compact jets is observed in 8.4 GHz band; this builds mounting evidence that jet production may be prevalent even radio-quiet Seyferts. Assuming comparatively negligible local diffuse emission nucleus, also demonstrate an inverse correlation Lradio ∝ L −0.72±0.04 . If A configuration excluded case where plays significant role, relation still −0.12±0.05 Current research linking mass supermassive black holes stellar-mass “low/hard” state to luminosities suggests “fundamental plane accretion onto holes” has positive 0.67±0.12 Our differ from by more than 11σ (6σ excluding configuration), indicating separate mode ejection operate system. review literature shows seen three other hole systems, all which accrete at near 10% their Eddington luminosity, perhaps suggesting distinct disk–jet coupling high fractions. discuss our context disks across scale.
