The difference between the axial and polar perturbations exists in their effective potentials. For the axial perturbation around a Schwarzschild black hole, the effective potential reads However for ...

Until now, researchers have relied on powerful supercomputers to simulate black hole interactions that require refining black hole trajectories step by step, a process that is effective but slow ...

Researchers have discovered that ultra-fast wind surrounding a supermassive black hole is not smooth and continuous as previously assumed, but instead resembles a rapid-fire stream of gas "bullets.

Read the paper: Structured ionized winds shooting out from a quasar at relativistic speeds No light or matter can escape from inside a black hole. However, dust and gas that is pulled towards the ...

The project utilized over 300,000 core hours of high-performance computing at the Zuse Institute Berlin to solve the equations governing black hole interactions, demonstrating the indispensable ...

A new study achieves unprecedented accuracy in modelling extreme cosmic events like black hole and neutron star collisions by calculating the fifth post-Minkowskian (5PM) order, crucial for ...

Read the paper: Emergence of Calabi–Yau manifolds in high-precision black-hole scattering A decade ago, the cosmos could be observed only with light, or occasionally with subatomic particles ...

Also called black hole “mergers,” such events are the cacophonous moment when these dense gravitational behemoths smash together to form a single, larger beast. Plefka and his colleagues are ...

In a cosmic first, astronomers observed a supermassive black hole consuming a star. This happened outside the core of its host galaxy. The event, named AT2024tvd, occurred 600 million light-years away ...

A quasar, powered by a supermassive black hole consuming matter, emits immense energy. Using the NASA/ESA Hubble Space Telescope, astronomers found that intense radiation pressure near the black hole ...
