One-dimensional linear analysis and numerical simulations of Alfven waves in a force-free magnetosphere around a Kerr black hole
Shinji Koide, Sousuke Noda, Masaaki Takahashi
We perform one-dimensional linear analysis and numerical simulations of the propagation of Alfven waves in a force-free magnetosphere along magnetic field lines around a spinning b…
Parametrized-Post-Newtonian Test of Black Hole Spacetime for Galactic Center Massive Black Hole Sgr A*: Formulation and Fitting
Hiromi Saida, Sena A. Matsui, Tsutomu T. Takeuchi +4
We have performed a parametrized post-Newtonian (PPN) test of a black hole spacetime using observational data of the star S0-2/S2 orbiting the massive black hole at our galactic ce…
Mapping the distribution of the magnetic field strength along the NGC 315 jet
Motoki Kino, Hyunwook Ro, Masaaki Takahashi +4
We study magnetic field strengths along the jet in NGC~315. First, we estimated the angular velocity of rotation in the jet magnetosphere by comparing the measured velocity profile…
Origin of an Orbiting Star Around the Galactic Supermassive Black Hole
Shogo Nishiyama, Tomohiro Kara, Brian Thorsbro +6
The tremendous tidal force that is linked to the supermassive black hole (SMBH) at the center of our galaxy is expected to strongly subdue star formation in its vicinity. Stars wit…
Radial Velocity Measurements of an Orbiting Star Around Sgr A*
Shogo Nishiyama, Hiromi Saida, Yohsuke Takamori +10
During the next closest approach of the orbiting star S2/S0-2 to the Galactic supermassive black hole (SMBH), it is estimated that RV uncertainties of ~ 10 km/s allow us to detect…
