Abstract The Event Horizon Telescope (EHT) Collaboration recently published the first
images of the supermassive black holes in the cores of the Messier 87 and Milky Way …

We evolve two high-resolution general relativistic magnetohydrodynamic simulations of
advection-dominated accretion flows around nonspinning black holes (BHs), each over a …

In this article, we discuss the state of “AGN feedback” in radio-quiet (RQ) AGN. This study
involves heterogeneous samples of nearby Seyfert and LINER galaxies as well as quasi …

General relativistic magnetohydrodynamic (GRMHD) simulations have revolutionized our
understanding of black hole accretion. Here, we present a GPU-accelerated GRMHD code …

Feedback driven by jets from active galactic nuclei is believed to be responsible for reducing
cooling flows in cool-core galaxy clusters. We use simulations to model feedback from …

Spinning supermassive black holes (BHs) in active galactic nuclei magnetically launch
relativistic collimated outflows, or jets. Without angular momentum supply, such jets are …

Recent simulations find that hot gas accretion onto compact accretors is often highly
turbulent and diskless, and shows a power-law density profile with slope α ρ≈− 1. These …

Recent observations of galaxy clusters and groups with misalignments between their central
active galactic nucleus jets and X-ray cavities, or with multiple misaligned cavities, have …

Aims. The multifaceted central radio galaxy of the cluster RBS 797 shows several episodes
of jet activity in multiple directions. We wish to understand the causes behind these dramatic …

In this letter, we investigate Bondi-like accretion flows with zero or low specific angular
momentum by performing 3D general relativistic magnetohydrodynamic simulations. In …
