An HLLD Implementation for General Relativistic Magnetohydrodynamics in AthenaK

Jacob Fields, George N. Wong, James M. Stone

We present an implementation of an HLLD approximate Riemann solver for the AthenaK astrophysics code with support for full general relativistic magnetohydrodynamics via a tetrad fr…

Dynamics and geometry of the inner sub-parsec-scale jet in 3C 279 observed with the Event Horizon Telescope

Hendrik Mueller, Sebastiano D. von Fellenberg, Ai-Ling Zeng +275

The 2021 Event Horizon Telescope observations resolve the innermost jet region of the blazar 3C279 with unprecedented detail. The reconstructed images consistently reveal a compact…

The SANE, the MAD, and the Chimera

George N. Wong, James M. Stone

Non-radiative black hole accretion flows are commonly classified by their magnetic flux state, with standard and normal evolution (SANE) disks and magnetically arrested disks (MADs…

Prospects for Improving the Theoretical Uncertainty for Tests of General Relativity with the EHT

Lia Medeiros, George N. Wong, Feryal Ozel

We characterize the relationship between the size of the bright ring observed in simulated black hole images and the size of the analytic black hole shadow. Calibrating this relati…

Broadband multiwavelength properties of the archetypal blazar 3C 279 during the 2017 Event Horizon Telescope campaign

G. Principe, J. C. Algaba, E. Aviano +529

The archetypal blazar 3C 279 hosts a prominent relativistic jet and exhibits strong broadband variability across the electromagnetic spectrum. In April 2017, the Event Horizon Tele…

Is plasmoid-mediated reconnection really important in accretion flows to drive flares in AGNs?

Giovani H. Vicentin, Elisabete M. de Gouveia Dal Pino, George N. Wong +4

Based on very high-resolution resistive 2D and 3D magnetohydrodynamical (MHD) simulations of current sheets, our findings suggest that the answer to this question is likely no. In…
