Scientists have long thought that matter sucked by black holes builds up around them, forming a donut-like structure. Findings of a new study however, challenge this idea.
Rings Of Gas Around Black Holes Are Not Rigid Donut-like Structures
Computer simulations and observations from the ALMA observatory in Chile's Atacama Desert have revealed that the rings of gas that surround active supermassive black holes are not simple donut shapes.
Astronomers instead found that the gas expelled from the center of black holes interacts with the infalling gas and create a dynamic circulation pattern that resembles water fountains.
Takuma Izumi, from the National Astronomical Observatory of Japan (NAOJ), and colleagues used ALMA to observe a supermassive black hole in the Circinus Galaxy, which is about 14 million light-years away from Earth. They also used the supercomputer Cray XC30 ATERUI operated by NAOJ to simulate gas falling toward a black hole.
