Someone want to explain what this means and why it's important?

I just can’t not think “basic color scheme” when I see these graphs you gotta change it imo

Correct, just read it in his voice, from the article: “Pulsar wind nebulae are formed when outflows of relativistic electrons and positrons hit the surrounding supernova remnant or interstellar medium at a shock front.”

I’ll take a stab at this.

  • I think it is saying that there is a pulsar called Vela.
  • This pulsar shoots out photons which are really high energy (X-rays).
  • These photos are extremely polarized (aligned).
  • There is a limit to how highly aligned photons can become in a natural process (in this case an environment with extremely strong magnetic forces at work)
  • Given how highly aligned these photons are, they are able to make some educated guesses about the environment the X-rays are passing through (a nebula surrounding the pulsar), and possibly about the nature of the pulsar itself.

Abstract:

Pulsar wind nebulae are formed when outflows of relativistic electrons and positrons hit the surrounding supernova remnant or interstellar medium at a shock front. The Vela pulsar wind nebula is powered by a young pulsar (B0833-45, aged 11,000 years)1 and located inside an extended structure called Vela X, which is itself inside the supernova remnant2. Previous X-ray observations revealed two prominent arcs that are bisected by a jet and counter jet3,4. Radio maps have shown high linear polarization of 60% in the outer regions of the nebula5. Here we report an X-ray observation of the inner part of the nebula, where polarization can exceed 60% at the leading edge—approaching the theoretical limit of what can be produced by synchrotron emission.

We infer that, in contrast with the case of the supernova remnant, the electrons in the pulsar wind nebula are accelerated with little or no turbulence in a highly uniform magnetic field

Synchrotron? That lab in Saskatoon?

Then Why build synchrotrons on earth, when all the particle physicians can travel to space for their experiments?

I don't understand any of that. I'm happy for you though. Or sorry that happened.

Supernova's emit x-ray bursts and a wave of non-photon particles. If the particle wave hits a thick enough nebula, Physicsy Things happen that will polarise the x-rays. This process can only cause partial polarisation (60% ish) and usually well below that.

They found a supernova with x-rays polarized nearly to the limit, which would only be possible if the particles were a fluid flowing nearly perfectly with almost no turbulence. That would be, to put it mildly, a near trick.

Super glad they fixed this!!! The cardinal grammeters in my unilateral phase detractors haven’t been synchronized since ‘96, and our nofer trunnions are operating at like 12% because of it. Just barely good enough, and I still have to crawl in once a month and grease the spurving bearings.

Will they port this to legacy hardware, specifically the RetroEncabulator? No I don’t have the hyper, not everybody needs to spring for a dingle arm that’s not prefabulated amulite.

but what happens if we reverse the polarity using the quantum carburetor?
