AGN Jets from Formation to Dissipation

Anne-Kathrin Baczko, A. -K. Baczko, Eleni Vardoulaki +27

Active Galactic Nuclei (AGN) are among the most energetic phenomena in the Universe, capable of launching powerful relativistic jets that extend from sub-parsec to megaparsec scale…

Universal Radial Scaling of Large-Scale Black Hole Accretion for Magnetically Arrested And Rocking Accretion Disks

Aretaios Lalakos, Alexander Tchekhovskoy, Elias R. Most +3

Accretion onto supermassive black holes (BHs) can launch relativistic jets that inject energy and momentum into their surroundings. Understanding how such feedback shapes large-sca…

Galactic-scale Feeding Reveals Warped Hypermagnetized Multiphase Circumbinary Accretion Around Supermassive Black Hole Binaries

Hai-Yang Wang, Minghao Guo, Elias R. Most +2

Supermassive black hole (SMBH) binaries in gaseous and stellar environments are prime targets for next-generation space-based gravitational wave detectors. Yet, realistic accretion…

How to Turn Jets into Cylinders near Supermassive Black Holes in 3D GRMHD Simulations

Valeriia Rohoza, Aretaios Lalakos, Max Paik +4

Accreting supermassive black holes (SMBHs) produce highly magnetized relativistic jets that tend to collimate gradually as they propagate outward. However, recent radio interferome…

Jets with a Twist: Emergence of FR0 Jets in 3D GRMHD Simulation of Zero Angular Momentum Black Hole Accretion

Aretaios Lalakos, Alexander Tchekhovskoy, Omer Bromberg +4

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

Striped Jets in Post Neutron Star Merger Systems

Emma Kaufman, I. M. Christie, A. Lalakos +2

Models invoking magnetic reconnection as the particle acceleration mechanism within relativistic jets often adopt a gradual energy dissipation profile within the jet. However, such…

Black hole to photosphere: 3D GRMHD simulations of collapsars reveal wobbling and hybrid composition jets

Ore Gottlieb, Matthew Liska, Alexander Tchekhovskoy +4

Long-duration -ray bursts (GRBs) accompany the collapse of massive stars and carry information about the central engine. However, no 3D models have been able to follow these jet…

Bridging Bondi and Event Horizon Scales: 3D GRMHD Simulations Reveal X-Shaped Radio Galaxy Morphology

Aretaios Lalakos, Ore Gottlieb, Nick Kaaz +6

X-shaped radio galaxies (XRGs) produce misaligned X-shaped jet pairs and make up of radio galaxies. XRGs are thought to emerge in galaxies featuring a binary superma…

Black hole to breakout: 3D GRMHD simulations of collapsar jets reveal a wide range of transients

Ore Gottlieb, Aretaios Lalakos, Omer Bromberg +2

We present a suite of the first 3D GRMHD collapsar simulations, which extend from the self-consistent jet launching by an accreting Kerr black hole (BH) to the breakout from the st…

The Role of Magnetic Field Geometry in the Evolution of Neutron Star Merger Accretion Discs

I. M. Christie, A. Lalakos, A. Tchekhovskoy +4

Neutron star mergers are unique laboratories of accretion, ejection, and r-process nucleosynthesis. We used 3D general relativistic magnetohydrodynamic simulations to study the rol…
