Objects that are on the verge of being extremal black holes but actually are distinct in many ways are called quasi black holes. Quasi black holes are defined here and treated in a unified way through ...

Such interactions between black holes or neutron stars (compact remnants of exploded massive stars) can be studied through the deflection angle, the energy released through the near miss and the ...

Researchers have finally confirmed that black holes spin. By watching the radio jet of the black hole at the center of the galaxy Messier 87, researchers were able to watch it tilt, a movement ...

An artist’s impression of high-speed winds, illustrated in white, being ejected from the vicinity of a supermassive black hole. Credit: JAXA. Black holes are objects that are so dense that not ...

The curious minds at What If reveal the hidden black hole scientists recently discovered near Earth. At least 5 dead after severe storm, including possible tornado, batters St. Louis, mayor says ...

In the occipital lobe, ZSP and FSP were 0.42 and for the parietal lobe, 0.26 (ZSP) and 0.22 (FSP). For WSens, ZSP and FSP values were 0.69 and 0.67, respectively. The RSens for the privately ...

Measurements of wind in a luminous galactic core reveal dense pockets of gas — a finding that calls for a rethink of how black holes interact with their host galaxies. Read the paper ...

A prediction of the gravitational waves produced by interacting black holes achieves high precision and demonstrates the link between general relativity and geometry. Read the paper: Emergence of ...

Not directly. Since light can’t escape them, black holes are invisible. But we can "see" them indirectly by observing how they affect nearby stars, gas, or light, such as glowing disks of material ...

A wandering black hole rips a star to shreds before swallowing it in a spectacular burst of radiation. The paper published in the Astrophysical Journal Letters by the University of California ...

A supermassive black hole around a million times the mass of the Sun just gave away its position in spectacular fashion. When a passing star veered a little too close, it was torn apart in the black ...
