Scientists detect radio echoes of a black hole feeding on a star

https://m.phys.org/news/2018-03-scientists-radio-echoes-black-hole.html

"We know that the radio waves are coming from really energetic electrons that are moving in a magnetic field—that is a well-established process," Pasham says. "The debate has been, where are these really energetic electrons coming from?"

Some scientists propose that, in the moments after the stellar explosion, a shockwave propagates outward and energizes the plasma particles in the surrounding medium, in a process that in turn emits radio waves. In such a scenario, the pattern of emitted radio waves would look radically different from the pattern of X-rays produced from infalling stellar debris.

"What we found basically challenges this paradigm," Pasham says."

Yes, i already know what is going on.

From this same data, Pasham and van Velzen calculated the size of the X-ray-emitting region to be about 25 times the size of the sun, while the radio-emitting region was about 400,000 times the solar radius.

"It's not a coincidence that this is happening," Pasham says. "Clearly there's a causal connection between this small region producing X-rays, and this big region producing radio waves."

The team proposes that the radio waves were produced by a jet of high-energy particles that began to stream out from the black hole shortly after the black hole began absorbing material from the exploded star. Because the region of the jet where these radio waves first formed was incredibly dense (tightly packed with electrons), a majority of the radio waves were immediately absorbed by other electrons.

It was only when electrons traveled downstream of the jet that the radio waves could escape—producing the signal that the researchers eventually detected. Thus, they say, the strength of the jet must be controlled by the accretion rate, or the speed at which the black hole is consuming X-ray-emitting stellar debris."

Yes yes.

That all with my terrible english. Maybe you can get a point. I hope so 😀

Galaxy center supermassive concentration expanding and emit dark expanding matter

When this dark expanding pushing force particle moving inside expanding star, there is expanding pushing force from star expanding nucleus of atoms.

That expanding pushing force pushing inside this dark expanding particle which start expanding faster and faster. Finally this dark expanding particle is not dark for us.

Thats why expanding star expanding nucleus of atoms start also expanding faster and it is start pushing away from expanding star center and it is that way where is supermassive concentration and all that with out pulling force and with out curving space.
