An MHD-informed model with self-consistent radial profiles applied to ten z >= 2.5 quasar jets yields higher jet powers than one-zone models, favors electron distributions tied to gas pressure, and finds low magnetization with no clear redshift trend in Lorentz factor.

abstract
We describe our program to search for and study the kilo-parsec scale radio jets in a sample of high-redshift (greater than 3.4), flat spectrum quasars using new and archival VLA data. Two of these radio jets have been imaged with Chandra, and have X-ray counterparts and are briefly discussed. These high-redshift sources are important targets for testing current X-ray jet emission models for kpc-scale jets and follow-up multi-wavelength observations will shed light on this problem.

Broad-band Spectral Modeling of Large-Scale X-ray Jets in High-Redshift Quasars: An MHD-Informed Approach
An MHD-informed model with self-consistent radial profiles applied to ten z >= 2.5 quasar jets yields higher jet powers than one-zone models, favors electron distributions tied to gas pressure, and finds low magnetization with no clear redshift trend in Lorentz factor.
