Black holes also have a corona, but astronomers have struggled to completely understand its shape and how it relates to the accretion disk of material that surrounds actively feeding black holes ...

This finding suggests that noncommutative geometry may inherently encode quantum effects in curved spacetime, providing a new perspective on black hole thermodynamics. Another line of inquiry has ...

Scientists have discovered that some supermassive black holes rotate much more rapidly than expected. The discovery came as ...

2). These models can be fit to X-ray data to learn about the changing geometry of the X-ray continuum source. Fig. 1: A computer visualisation of the intensity of X-ray emission from an accretion disk ...

By combining data from NASA’s IRAS and NuSTAR telescopes, scientists have uncovered more hidden supermassive black holes than earlier estimates suggested. Their findings indicate that over a third of ...
