A model for the image structure and spectral energy distribution of relativistic jets
Dominic W. Pesce, Ramesh Narayan, Yuh Tsunetoe
Upcoming advances in high-frequency VLBI promise to enable spatially resolved studies of astrophysical jets across an increasingly large source population. We present here a Python…
Spatially resolved spectral properties of M87* on event horizon scales
Shan-Shan Zhao, Ru-Sen Lu, Rocco Lico +2
The supermassive black hole at the center of the nearby radio galaxy M87 (M87*) is a prime target for studying black hole physics. Spatially resolved spectral measurements on event…
Black Hole Explorer Mission Development in Japan
Kazunori Akiyama, Mareki Honma, Akihiro Doi +21
The Black Hole Explorer (BHEX) is a next-generation space very-long-baseline interferometry (VLBI) mission concept that will extend existing ground-based millimeter/submillimeter V…
Multifrequency Synthesis via CHIBI: Colorful Hierarchical Interferometric Bayesian Imaging
Erandi Chavez, Paul Tiede, Sara Issaoun +4
From magnetized plasma of relativistic jets to dust grains within protoplanetary disks, we study the emission mechanisms of radio sources via their rich spectral structure. Multifr…
Slow-Light Effect in the Jet-Launching Region of M87
Yuh Tsunetoe, Dominic W. Pesce, Ramesh Narayan
We explore the impact of "slow-light" radiative transfer - i.e., general relativistic radiative transfer (GRRT) calculations in which the simulated fluid evolves while light rays a…
Limb-Brightened Jet in M87 from Anisotropic Nonthermal Electrons
Yuh Tsunetoe, Dominic W. Pesce, Ramesh Narayan +5
Very long baseline interferometry observations reveal that relativistic jets like the one in M87 have a limb-brightened, double-edged structure. Analytic and numerical models strug…
Jet Archaeology and Forecasting: Image Variability and Magnetic Field Configuration
Yuh Tsunetoe, Ramesh Narayan, Angelo Ricarte
We investigate how magnetic field variations around accreting black holes on event horizon scales affect the morphology of magnetically-driven jet on larger scales. By performing r…
Survey of Non-thermal Electron around Supermassive Black Holes through Polarization Flips
Yuh Tsunetoe, Tomohisa Kawashima, Ken Ohsuga +1
Optically thick non-thermal synchrotron sources notably produce linear polarization vectors being parallel to projected magnetic field lines on the observer's screen, although they…
Black Hole Spacetime and Properties of Accretion Flows and Jets Probed by Black Hole Explorer: Science Cases Proposed by BHEX Japan Team
Tomohisa Kawashima, Yuh Tsunetoe, Ken Ohsuga +7
Black Hole Explorer (BHEX) is a space VLBI mission concept, which can probe the black hole spacetime and the plasma properties including the magnetic fields of the accretion flows…
The Japanese Vision for the Black Hole Explorer Mission
Kazunori Akiyama, Kotaro Niinuma, Kazuhiro Hada +43
The Black Hole Explorer (BHEX) is a next-generation space very long baseline interferometry (VLBI) mission concept that will extend the ground-based millimeter/submillimeter arrays…
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…
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…
Polarization images of accretion flow around supermassive black holes: imprints of toroidal field structure
