Gravity causes matter to clump together, forming everything from stars to planets. Accretion disks form when material swirls around a central object due to conserved angular momentum. Magnetic fields ...

A model of ultraviolet and optical emission from the tidal disruption event AT 2018hyz is shown in this schematic diagram. As an accretion disk forms quickly after the TDE, it generates x-ray emission ...

The researchers used the Atacama Large Millimeter/submillimeter Array (ALMA), combined with maser astrometry—a way to measure the positions of gas using microwaves—to trace the complete process of gas ...

Researchers accidentally stumbled on a way to measure the size of the accretion disks of dust, gas and plasma that surround black holes. When you purchase through links on our site, we may earn an ...
