I thought the jets emitted were made of anti matter? (Anyone?)
Interesting principle, as I understood it, was that the jet diameter to turbulent transition to laminar flow length held to similar principles as (roughly), gaseous (which would include liquids) in practical day to day physics. (Compare a jet from a propane torch.)
Meaning diameter to length ratios, affected by velocity(pressure) and density.
Of course that is a simplification, but relative to such distance observations, seems to fit accepted models.
Very interesting that now we can study The magnetic fields on such a large scale.
Which then raises another deep hole to climb into (pun intended), how do those ratios (proportions) compare to those we see in our physical world, at the molecular level.
- pfdietz 3y agoHow could they possibly be made of antimatter? They can contain antimatter (particularly positrons), but what physical process could possibly create antimatter and then separate it from matter?
- elashri 3y agoWhile we don't know much about the content of the jets. We know that there are ordinary matter in there. Specifically we observed nickel and iron [1]. The positive charge in these jets was initially unclear, with possibilities being either positrons (the antimatter 'opposite' of electrons) or positively charged atoms. However, the discovery of nickel and iron indicates that the positive charge is provided by positively charged atoms, not positrons [1] https://phys.org/news/2013-11-astronomers-reveal-contents-mysterious-black.html https://phys.org/news/2013-11-astronomers-reveal-contents-my...
- chasil 3y agoWe can see the long range content of these jets when they are pointed directly at us as "blazars" which do produce positrons. "Gas, dust and the occasional star are captured and spiral into this central black hole, creating a hot accretion disk which generates enormous amounts of energy in the form of photons, electrons, positrons and other elementary particles." https://en.m.wikipedia.org/wiki/Blazar https://en.m.wikipedia.org/wiki/Blazar The general discussion of astrophysical jets describe them as formed from regular matter. There would be some quantity of antimatter initially, but it would quickly be consumed and converted to gamma rays. https://en.m.wikipedia.org/wiki/Astrophysical_jet https://en.m.wikipedia.org/wiki/Astrophysical_jet
