Two key findings emerged from the observations, gathered using several ground- and space-based telescopes. The first step was better model what happens as the dying star collapses. The data suggests that the black hole creates a strong magnetic field that initially overwhelms jets of matter and energy formed because of the explosion. Then, the magnetic field breaks down, the study authors said.
In the next phase, the magnetic field diminishes, allowing matter to dominate the jets. Before, scientists thought that jets could be dominated only by the magnetic field or matter — not both.
Another insight concerns what kind of radiation is responsible for the bright phase at the beginning of the burst, which astronomers call the "prompt" phase. Before, several types of radiation were considered, including so-called blackbody radiation (heat emission from an object) and inverse Compton radiation (which happens when accelerated particles transfer energy to photons), according to the statement.
It turns out that a phenomenon called synchrotron radiation is behind the prompt phase. This kind of radiation happens when electrons accelerate in a curved or spiral pathway, propelled along by an organized magnetic field.
"Synchrotron radiation is the only emission mechanism that can create the same degree of polarization and the same spectrum we observed early in the burst," Troja said.

So now we know who to blame for Je$$e Jack$on, Al $harpton, Mad Maxine, Zero, Mooch, Hank “Guam’s Tipping Over” Johnson...
Huh?
“The first step was better model what happens as the dying star collapses.”
Is the author expecting us to take her seriously writing like that ? Maybe she’s in the wrong field.
I’ll translate....
Big black hole make big boom, big flash. Scientists believe the energy given off is in various parts of the EM spectrum.
Appx 10 billion light years. A long time ago. Though an instant for God.
