The new observations help explain how accretion disks around black holes take shape.
This finding is significant because lower polarization values can be explained by various other processes, but"there are very few things in the universe that can make highly polarized light," Liodakis said.blasting out of a black hole, which stirs material around the black hole and sometimes ejects it into the surrounding emptiness. So the study team used the Karl G.
Just like some sunglasses polarize sunlight by filtering some of it to reduce glare, light is polarized when it is emitted in pockets of space that are magnetized. Around the black hole studied in the new paper, the disrupted star's magnetic field may have accelerated particles enough to emit, which is naturally polarized to the high amounts the team detected. Alternatively, the magnetic field itself may be"stretched along the stream," leading to a high polarization, Liodakis said.
The new study is one of the few measuring polarization of optical light from accretion disks, so more observations and computer simulations are needed to understand which of the two scenarios is responsible for the polarized light as well as how rare it is, he added. "This is very exciting, because it suggests that reality might be more complicated than we thought," said Giorgos Leloudas, who is a scientist studying TDEs at the National Space Institute at the Technical University of Denmark and wasn't involved in the latest study."There might be multiple ways to create emission by tidal disruption events."was published Thursday in the journal Science.
