Do Circumnuclear Dense Gas Disks Drive Mass Accretion onto Supermassive Black Holes?
Takuma Izumi, Nozomu Kawakatu, Kotaro Kohno
We present a positive correlation between the mass of dense molecular gas () of pc scale circumnuclear disks (CNDs) and the black hole mass accretion rate…

AGN Jet Power, Formation of X-ray Cavities, and FR I/II Dichotomy in Galaxy Clusters
Yutaka Fujita, Nozomu Kawakatu, Isaac Shlosman
We investigate the ability of jets in active galactic nuclei (AGNs) to break out of the ambient gas with sufficiently large advance velocities. Using observationally estimated jet…

Evidence for a significant mixture of electron/positron pairs in FRII jets constrained by cocoon dynamics
Nozomu Kawakatu, Motoki Kino, Fumio Takahara
We examine the plasma composition of relativistic jets in four FRII radio galaxies by analyzing the total cocoon pressure in terms of partial pressures of thermal and non-thermal e…
