Three-dimensional Relativistic MHD Simulations of Active Galactic Nuclei Jets: Magnetic Kink Instability and Fanaroff-Riley Dichotomy
Alexander Tchekhovskoy, Omer Bromberg
Energy deposition by active galactic nuclei jets into the ambient medium can affect galaxy formation and evolution, the cooling of gas flows at the centres of galaxy clusters, and…
Electron Thermodynamics in GRMHD Simulations of Low-Luminosity Black Hole Accretion
Sean M. Ressler, Alexander Tchekhovskoy, Eliot Quataert +2
Simple assumptions made regarding electron thermodynamics often limit the extent to which general relativistic magnetohydrodynamic (GRMHD) simulations can be applied to observation…
Ab-initio pulsar magnetosphere: the role of general relativity
Alexander A. Philippov, Benoît Cerutti, Alexander Tchekhovskoy +1
It has recently been demonstrated that self-consistent particle-in-cell simulations of low-obliquity pulsar magnetospheres in flat spacetime show weak particle acceleration and no…
Relativistic MHD simulations of core-collapse GRB jets: 3D instabilities and magnetic dissipation
Omer Bromberg, Alexander Tchekhovskoy
Relativistic jets naturally occur in astrophysical systems that involve accretion onto compact objects, such as core collapse of massive stars in gamma-ray bursts (GRBs) and accret…
Radio Pulsars
V. S. Beskin, S. V. Chernov, C. R. Gwinn +1
Almost 50 years after radio pulsars were discovered in 1967, our understanding of these objects remains incomplete. On the one hand, within a few years it became clear that neutron…
Horizon-Scale Lepton Acceleration in Jets: Explaining the Compact Radio Emission in M87
Avery E Broderick, Alexander Tchekhovskoy
It has now become clear that the radio jet in the giant elliptical galaxy M87 must turn on very close to the black hole. This implies the efficient acceleration of leptons within t…
