The intrinsic structure of Sagittarius A* at 1.3 cm and 7 mm

Ilje Cho, Guang-Yao Zhao, Tomohisa Kawashima +63

Sagittarius A* (Sgr A*), the Galactic Center supermassive black hole (SMBH), is one of the best targets to resolve the innermost region of SMBH with very long baseline interferomet…

Collimation of the relativistic jet in the quasar 3C 273

Hiroki Okino, Kazunori Akiyama, Keiichi Asada +32

The collimation of relativistic jets launched from the vicinity of supermassive black holes (SMBHs) at the centers of active galactic nuclei (AGN) is one of the key questions to un…

Event Horizon Telescope observations of the jet launching and collimation in Centaurus A

Michael Janssen, Heino Falcke, Matthias Kadler +236

Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of e…

The Variability of the Black-Hole Image in M87 at the Dynamical Time Scale

Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel +235

The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center o…

Morphological transition of the compact radio lobe in 3C84 via the strong jet-cloud collision

Motoki Kino, Kotaro Niinuma, Nozomu Kawakatu +8

We report multi-epoch Very Long Baseline Interferometric (VLBI) observations of the compact radio lobe in the radio galaxy 3C84 (NGC1275) during 2016 - 2020. The image sequence of…

Relativistic jet acceleration region in a black hole magnetosphere

Masaaki Takahashi, Motoki Kino, Hung-Yi Pu

We discuss stationary and axisymmetric trans-magnetosonic outflows in the magnetosphere of a rotating black hole (BH). Ejected plasma from the plasma source located near the BH is…
