New UNLV-led research is helping to unravel clues to a cosmic mystery that has eluded scientists for decades. Cataclysmic ...

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 ...

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 ...

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

When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the ...

A research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with other researchers, has developed a new method to estimate how stellar-mass compact objects ...

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.

The step-by-step process of gas transport to form accretion disks had not previously been understood. The researchers used the Atacama Large Millimeter/submillimeter Array (ALMA), combined with maser ...

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.

Associate Professor CAI Zhenyi and Professor WANG Junxian from the Department of Astronomy at the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), through ...
