Detected: twin-jet-x-ray emission from an FRII source.
- Non-thermal X-ray emission from both jets of an FR II source has been detected for the FIRST TIME!
So it is worthwhile to search for new solutions like synchrotron radiaton produced by accelerating/decellerating electron jets between Galaxy anchor Black Holes (GABHs) in:

Radio galaxy 3C353 is a truly unique source, because its two jets - of the FRII type - are 4''-wide, and therefore can be well resolved by Chandra. Moreover,
We show that the detection of the X-ray emission associated with the
radio knots and counter knots, which is most likely non-thermal in origin, puts several crucial constraints on
the X-ray emission mechanisms in powerful large-scale jets of quasars and FR II sources. In particular, we
show that this detection is inconsistent with the inverse-Compton model proposed in the literature, and instead
implies a synchrotron origin of the X-ray jet photons.
However, A complete, self-consistent model for the X-ray emission of extragalactic jets still remains elusive

- We don’t know, whether kpc-scale jets’ knots are moving or
stationary features (or a combination of both?).
- Stationary features may be associated with reconfinement
shocks, but the most simple models don’t explain the positional
offsets between X-ray and radio knots.
- Moving features (internal shocks) would associate radio knots
with forward shocks and X-ray knots with reverse shocks. This is
the paper authors’ choice, but open questions remain.
- How these shocks produce much different electron populations?
- Why are knots so similar to the hotspots?
Twin
.- Non-thermal X-ray emission from both jets of an FR II source has
been detected for the first time.
- The X-ray knots are significantly narrower and closer to the core
than their radio counterparts, their X-ray-to-radio brightness ratio
decreases along the jets.
- Explaining the X-ray emission mechanism in the knots is quite a
challenge, but synchrotron models are favoured
