The jet and resolved features of the central supermassive black hole of M 87 observed with EHT
Makoto Miyoshi, Yoshiaki Kato, Junichiro Makino
We report our independent image reconstruction of the M 87 from the public data of the Event Horizon Telescope Collaborators (EHTC). Our result is different from the image publishe…
Radiation Magnetohydrodynamic Simulations of Sub-Eddington accretion Flows in AGN: Origin of Soft X-ray Excess and Rapid Time Variabilities
Taichi Igarashi, Yoshiaki Kato, Hiroyuki R. Takahashi +3
We investigate the origin of the soft X-ray excess component in Seyfert galaxies observed when their luminosity exceeds 0.1% of the Eddington luminosity (). The e…
Vortex Flows in the Solar Chromosphere -- I. Automatic detection method
Yoshiaki Kato, Sven Wedemeyer
Solar "magnetic tornadoes" are produced by rotating magnetic field structures that extend from the upper convection zone and the photosphere to the corona of the Sun. Recent studie…
Chromospheric and Coronal Wave Generation in a Magnetic Flux Sheath
Yoshiaki Kato, Osker Steiner, Viggo Hansteen +3
Using radiation magnetohydrodynamic simulations of the solar atmospheric layers from the upper convection zone to the lower corona, we investigate the self-consistent excitation of…
Solar science with the Atacama Large Millimeter/submillimeter Array - A new view of our Sun
S. Wedemeyer, T. Bastian, R. Brajsa +35
The Atacama Large Millimeter/submillimeter Array (ALMA) is a new powerful tool for observing the Sun at high spatial, temporal, and spectral resolution. These capabilities can addr…
SSALMON - The Solar Simulations for the Atacama Large Millimeter Observatory Network
S. Wedemeyer, T. Bastian, R. Brajsa +27
The Solar Simulations for the Atacama Large Millimeter Observatory Network (SSALMON) was initiated in 2014 in connection with two ALMA development studies. The Atacama Large Millim…
