In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion ...

Astronomers have identified the first clear evidence of a magnetar forming during a superluminous supernova, offering new insight into some of the brightest explosions in the universe.

Through the study of the optical to extreme ultraviolet radiation generated by the accretion of supermassive black holes at the centers of quasars, Associate Professor Cai Zhenyi and Professor Wang ...

An international scientific team has revealed for the first time the magnetic field transport processes in the accretion flow of a black hole and the formation of a "MAD"—a magnetically arrested ...

Add Yahoo as a preferred source to see more of our stories on Google. An illustration of a black hole with an accretion disk, accompanied by diagrams showcasing the team's research. Astronomers have ...

Researchers conducted innovative simulations of spinning black holes grounded in general relativity, which clarified that the ultraluminous accretion disk (i.e., gaseous spiral surrounding a black ...

Accretion is one of the most fundamental processes in the cosmos. It is a universal phenomenon triggered by gravity, and the process by which bits of matter accumulate and coalesce with more bits of ...

The research team created a spinning disk of plasma that mimics the superheated gas in accretion disks that gradually feed black holes. When you purchase through links on our site, we may earn an ...

Some of the most extreme explosions in the universe are Type I superluminous supernovae. “They are one of the brightest ...

Supermassive black holes may tear apart and devour their disk of surrounding dust and gas at a shocking speed, perhaps explaining the behavior of a mysterious class of rapidly brightening quasar.

Astronomers have viewed the outer region of an active supermassive black hole's accretion disk, thereby improving our understanding of these feeding cosmic monsters. When you purchase through links on ...
