The black hole’s spin axis is assumed to align vertically. The jet’s direction is almost perpendicular to the disk. The misalignment between the black hole spin axis and the disk rotation axis ...

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 ...

Lab top accretion disc: Cutaway diagram of the experimental setup used by Wang and colleagues. The data shown in the left portion of the gap between cylinders illustrates the simulated shear profile ...

A newly identified quasar shows sustained growth beyond the Eddington limit, prompting new examination of accretion physics, radiation trapping and jet activity in early supermassive black holes.
