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…
