Interface instabilities in hydrodynamic relativistic jets [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
Both the dynamics and the observational properties of relativistic jets are determined by their interaction with the ambient medium. A crucial role is played by the contact discontinuity at the jet boundary, which in the presence of jet collimation may

Espresso and Stochastic Acceleration of Ultra-high-energy Cosmic Rays in Relativistic Jets [PDF]

open access: yesAstrophysical Journal, 2021
In the espresso scenario, ultra-high-energy (UHE) cosmic rays (CRs) are produced via a one-shot reacceleration of galactic-like CRs in the relativistic jets of active galactic nuclei, independently of the scattering rate dictated by magnetic fluctuations.

The propagation of relativistic jets in expanding media [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
We present a comprehensive analytic model of relativistic jet propagation in expanding homologous media (ejecta). This model covers the entire jet evolution as well as a range of configurations that are relevant to binary neutron star mergers.

A Simulation Study of Ultra-relativistic Jets–I. A New Code for Relativistic Hydrodynamics [PDF]

open access: yesAstrophysical Journal, 2021
In an attempt to investigate the structures of ultra-relativistic jets injected into the intracluster medium (ICM) and the associated flow dynamics, such as shocks, velocity shear, and turbulence, we have developed a new special relativistic hydrodynamic

The Powers of Relativistic Jets Depend on the Spin of Accreting Supermassive Black Holes [PDF]

open access: yes, 2021
Theoretical models show that the power of relativistic jets of active galactic nuclei depends on the spin and mass of the central supermassive black holes, as well as the accretion.

GRMHD Simulations and Modeling for Jet Formation and Acceleration Region in AGNs

open access: yesUniverse, 2022
Relativistic jets are collimated plasma outflows with relativistic speeds. Astrophysical objects involving relativistic jets are a system comprising a compact object such as a black hole, surrounded by rotating accretion flows, with the relativistic jets

Particle-in-Cell Simulations of Astrophysical Relativistic Jets

open access: yesUniverse, 2021
Astrophysical relativistic jets in active galactic nuclei, gamma-ray bursts, and pulsars is the main key subject of study in the field of high-energy astrophysics, especially regarding the jet interaction with the interstellar or intergalactic ...

Absorbed relativistic jets in radio-quiet narrow-line Seyfert 1 galaxies [PDF]

open access: yesAstronomy & Astrophysics, 2020
Narrow-line Seyfert 1 (NLS1) galaxies are peculiar active galactic nuclei. Most of them do not show strong radio emission, but seven radio-quiet (or radio-silent) NLS1s have recently been detected flaring multiple times at 37 GHz by the Metsähovi Radio ...

Kink instabilities in relativistic jets can drive quasi-periodic radiation signatures [PDF]

open access: yes, 2020
Relativistic jets are highly collimated plasma outflows emerging from accreting black holes. They are launched with a significant amount of magnetic energy, which can be dissipated to accelerate nonthermal particles and give rise to electromagnetic ...
