Polarization images of accretion flow around supermassive black holes: imprints of toroidal field structure
Yuh Tsunetoe, Shin Mineshige, Ken Ohsuga +2
With unprecedented angular resolution, the Event Horizon Telescope (EHT) has opened a new era of black holes. We have previously calculated the expected polarization images of M87*…
Gravitational Test Beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole
Dimitrios Psaltis, Lia Medeiros, Pierre Christian +185
The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new…
A Jet-Bases Emission Model of the EHT 2017 Image of M87*
Tomohisa Kawashima, Kenji Toma, Motoki Kino +3
We carry out general relativistic ray-tracing radiative-transfer calculations to study whether a localized emission from plasma rings created at the stagnation surface in…
Super-resolution Imaging of the Protoplanetary Disk HD 142527 Using Sparse Modeling
Masayuki Yamaguchi, Kazunori Akiyama, Takashi Tsukagoshi +7
With an emphasis on improving the fidelity even in super-resolution regimes, new imaging techniques have been intensively developed over the last several years, which may provide s…
SYMBA: An end-to-end VLBI synthetic data generation pipeline
F. Roelofs, M. Janssen, I. Natarajan +203
Realistic synthetic observations of theoretical source models are essential for our understanding of real observational data. In using synthetic data, one can verify the extent to…
Polarization Imaging of M87 Jets by General Relativistic Radiative Transfer Calculation based on GRMHD Simulations
Yuh Tsunetoe, Shin Mineshige, Ken Ohsuga +2
The spectacular images of the M87 black hole taken by the Event Horizon Telescope (EHT) have opened a new era of black hole research. One of the next issues is to take polarization…
