Zero net flux MRI-turbulence in disks sustenance scheme and magnetic Prandtl number dependence
George Mamatsashvili, George Chagelishvili, Martin E. Pessah +2
We investigate sustenance and dependence on magnetic Prandtl number () for magnetorotational instability (MRI)-driven turbulence in astrophysical Keplerian disks with zer…
Simulating the dynamics and non-thermal emission of relativistic magnetised jets I. Dynamics
Dipanjan Mukherjee, Gianluigi Bodo, Andrea Mignone +2
We have performed magneto-hydrodynamic simulations of relativistic jets from supermassive blackholes over a few tens of kpc for a range of jet parameters. One of the primary aims w…
Numerical study of Kelvin-Helmholtz instability and its impact on synthetic emission from magnetized jets
Nikhil Borse, Sriyasriti Acharya, Bhargav Vaidya +4
Non-thermal emission from Active Galactic Nuclei (AGN) jets extends up-to large scales in-spite of them being prone to a slew of magneto-hydrodynamic instabilities. The main focus…
The different flavors of extragalactic jets: the role of relativistic flow deceleration
P. Rossi, G. Bodo, S. Massaglia +1
We perform three-dimensional numerical simulations of relativistic (with a Lorentz factor of 10), non magnetized jets propagating in a uniform density environment, in order to stud…
Kink-driven magnetic reconnection in relativistic jets: consequences for X-ray polarimetry of BL Lacs
Gianluigi Bodo, Fabrizo Tavecchio, Lorenzo Sironi
We investigate with relativistic MHD simulations the dissipation physics of BL Lac jets, by studying the synchrotron polarization signatures of particles accelerated by the kink in…
