Unprecedented Features Found in Brightest Cosmic Explosion on Record

The brightest gamma-ray explosion ever recorded, nicknamed BOAT, has been found to have a unique jet structure that may have caused its extreme brightness. The explosion, which was about 100 times brighter than any other recorded, likely marked the birth of a black hole. The jet ejected by the explosion was found to have a narrow core with wider, sloping sides, which dragged a large amount of stellar material along with it. This discovery sheds new light on the origins of the universe and could help scientists learn more about how stars first formed.

Unraveling the Mystery of the Brightest Cosmic Explosion Ever Recorded.

The Brightest of All Time (BOAT) cosmic explosion, caused by the collapse of a massive star and the birth of a black hole, was angled directly at Earth and dragged along an unusually large amount of stellar material in its wake, according to an international team of astrophysicists. The team's findings, published in Science Advances, suggest that the GRB had a unique structure, with a narrow jet embedded within a wider gas outflow. The researchers believe that the amount of mixing between the stellar material and the jet made the difference in this case, resulting in the slow fade of the afterglow.

Unraveling the Mystery of Runaway Black Holes and Their Feeding Behavior.

Astronomers have observed streams of star matter that collided with each other and came full circle around black holes, providing a direct look at the early stages of disk-forming around black holes. The team studying a tidal disruption event called AT 2020mot found strong evidence for the theory that the light is from star matter in the disk-forming stage. The team also calculated how polarized the detected light is and found that the light was polarized to an extraordinary amount (25%). The highly polarized light is due to the shocks created from multiple colliding streams of stellar material.
