Diverse Polarimetric Features of AGN Jets from Various Viewing Angles: Towards a Unified View
Yuh Tsunetoe, Shin Mineshige, Tomohisa Kawashima +3
Here, we demonstrate that polarization properties show a wide diversity depending on viewing angles. To simulate images of a supermassive black hole and surrounding plasma, we perf…
Implications from the velocity profile of the M87 jet: a possibility of a slowly rotating black hole magnetosphere
Motoki Kino, Masaaki Takahashi, Tomohisa Kawashima +4
Motivated by the measured velocity profile of the M87 jet using the KVN and VERA Array (KaVA) by Park et al. indicating that the starting position of the jet acceleration is farthe…
Large-scale outflow structure and radiation properties of super-Eddington flow: Dependence on the accretion rates
Shogo Yoshioka, Shin Mineshige, Ken Ohsuga +2
In order to precisely evaluate the impacts by super-Eddington accretors to their environments, it is essential to assure a large enough simulation box and long computational time t…
Resolving the inner parsec of the blazar J1924-2914 with the Event Horizon Telescope
Sara Issaoun, Maciek Wielgus, Svetlana Jorstad +27
The blazar J1924-2914 is a primary Event Horizon Telescope (EHT) calibrator for the Galactic Center's black hole Sagittarius A*. Here we present the first total and linearly polari…
Millimeter light curves of Sagittarius A* observed during the 2017 Event Horizon Telescope campaign
Maciek Wielgus, Nicola Marchili, Ivan Marti-Vidal +28
The Event Horizon Telescope (EHT) observed the compact radio source, Sagittarius A* (Sgr A*), in the Galactic Center on 2017 April 5-11 in the 1.3 millimeter wavelength band. At th…
Structure of the super-Eddington outflow and itsimpact on the cosmological scale
Ignacio Botella, Shin Mineshige, Takaaki Kitaki +2
It is one of the biggest issues in black hole (BH) astrophysics how to precisely evaluate BH feedback to its environments. Aiming at studying the unique gas dynamics of super-Eddin…
Mushroom-instability-driven Magnetic Reconnections in Collisionless Relativistic Jets
Tomohisa Kawashima, Seiji Ishiguro, Toseo Moritaka +2
We study the kinetic plasma dynamics in collisionless relativistic jets with velocity shear, by carrying out particle-in-cell simulations in the transverse plane of a jet. It is di…
Investigating the Disk-Jet Structure in M87 through Flux Separation in the Linear and Circular Polarization Images
Yuh Tsunetoe, Shin Mineshige, Tomohisa Kawashima +3
For testing different electron temperature () prescriptions in general relativistic magnetohydrodynamics (GRMHD) simulations through observations, we propose to utilize…
