A recent study in Physical Review Letters explores quantum effects on black hole thermodynamics and geometry, focusing on ...

If you’ve ever witnessed a solar eclipse, you might recall the Sun’s corona — its outermost atmosphere — a halo of glowing ...

Scientists developed a new model, which provides mathematical evidence that singularities are hidden inside black holes.

Black hole coronae are billions of degrees hot, which makes them a lot more difficult to study in detail. Using NASA’s IXPE ( ...

Results from the IXPE, which specializes in X-ray polarization, help map the shape and structure of coronas. IXPE observes X-rays, and studies objects that are not just small, but also very distant. X ...

In 1963, Roy Kerr, a New Zealand-based mathematician proposed a set of equations that explain the properties of rotating ...

Astounding simulation shows magnetic fields create fluffy, not flat, accretion disks around supermassive black holes, ...

The ultimate outcome of this dynamic process is still unclear, but the study implies that a black hole cannot stabilize in Kerr geometry, at least over long timescales, although the speed and ...

Black holes are the most extreme objects in the universe. These hyper-dense celestial phenomena exert gravitational forces so powerful that not even light can escape their pull, and time itself is ...

observations of the Galactic stellar black hole (BH) transient X-ray binary (XRB) systems XTE J1118+480 and GX 339−4 using an irradiated disc + compact jet model. In addition to quantifying the ...

How did supermassive black holes end up at the center of every galaxy? A while back, it wasn't that hard to explain: That's where the highest concentration of matter is, and the black holes had ...
