How Do Coiled Magnetic Fields in Black Holes Create Jets?

AI Thread Summary
Coiled magnetic fields are believed to generate jets observed along the rotational axis of black holes. These magnetic fields likely originate from the matter in the accretion disk rather than the black hole itself. The dynamics of the accretion disk matter, including its properties, play a crucial role in creating these magnetic fields. The jets consist of matter that may have specific charge properties, although the exact nature of this matter remains uncertain. Understanding these dynamics is essential for further insights into black hole behavior and jet formation.

I have read that coiled up magnetic fields are responsible for the jets that are observed along the axis of rotation of black holes.

I'm having trouble visualizing the "coiled up" magnetic field and where it comes from?

I presume that the field does not come from the matter in the black hole itself, right?

If it comes from the matter in the accretion disk, what are the properties and dynamics of the matter creating the field?

What are the properties of the matter being spewed in the jets in either direction? Any particular charge?

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
