Researchers have succeeded in measuring the inner edge of the disk of matter that orbits around a supermassive black hole in a quasar > 5B light yrs from earth(an object the size of our solar system that emits as much energy as a whole galaxy). It’s the most accurate measure achieved until now of such a small and distant object, and it has been achieved thanks to the so-called gravitational microlensing effect, caused by stars belonging to a galaxy between us and the quasar, and which may magnify tiny regions within the quasar.
In particular, they have managed to measure the inner edge of the disk o...
