“If they were purely made up of stars, they would be the densest galaxies in the universe.”
“Our study provides a new direction to understand the whole evolutionary history of massive stars toward the formation of black hole binaries.”
…
“We’re seeing what could be described as an energetic tug-of-war inside the black hole’s accretion flow.”
“It points to a slow starvation rather than a single dramatic death blow.”
“This result shows that the Event Horizon Telescope is not only useful for producing spectacular images, but can also be used to understand the physics that govern black hole jets.”

The Circinus Galaxy, a galaxy about 13 million light-years away, contains an active supermassive black hole that continues to influence its evolution. The largest source of infrared light from the region closest to the black hole itself was thought to be outflows, or streams of superheated matter that fire outward.

“This is a structure we’ve never seen before, so it could be a new class of dark object.”
“Nothing in my professional training as an X-ray astronomer had prepared me for something like this.”
“This was many times more energetic than any similar event and more than any known explosion powered by the collapse of a star.”
