Extragalactic jets with helical magnetic fields

2009
Extragalactic jets harbor dynamically important, organized magnetic fields. We explore with grid-adaptive, high resolution numerical simulations the morphology of AGN jets pervaded by helical field and flow topologies. We concentrate on the long term evolution of kinetic energy dominated jets, penetrating denser clouds. The jets have near-equipartition

Extragalactic magnetic fields

Reports on Progress in Physics, 1994
The observational methods for detecting and measuring extragalactic magnetic fields are discussed, along with some new indirect methods which could be used for inferring field strengths at large redshifts which are otherwise beyond the reach of direct measurement.

Extragalactic background light and extragalactic magnetic fields

AIP Conference Proceedings, 2012
VHE γ-rays from distant blazars several hundred Mpc away are attenuated through pair production interactions on extragalactic background light (EBL). Subsequent to their generation, electron/positron pairs proceed to produce γ-rays through IC interactions leading to the development of an electromagnetic (EM) cascade.

Magnetic-field configurations in compact extragalactic jets

Canadian Journal of Physics, 1986
Multifrequency and multitime polarimetry of active, compact radio sources strongly suggest that the magnetic-field structures in these sources are largely disordered or turbulent. Some initial, detailed model calculations of relativistic jets with turbulent fields have been performed in an effort to better understand the relationships between the ...

Magnetic Fields in Very Light Extragalactic Jets

2009
We simulate the propagation of very light astrophysical jets with density contrasts between 10−1 and 10−4 including magnetic fields into the intracluster medium on the galaxy cluster scale, using the magnetohydrodynamic code NIRVANA on the NEC SX-6 and SX-8.
