Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...
and accretion disk close to the black hole (e.g., its density, iron abundance, emissivity profile and ionization state). X-rays from accretion flows are highly variable, providing valuable additional ...
At the center of every black hole is a point of infinite density, called a singularity. It's what gives black holes their strong gravitational pull. And for decades, scientists thought ...
The black hole, with an official name of 1ES 1927+654, is located in the distant constellation Draco. Astronomers have been monitoring the black hole for years, primarily since 2018 when the mass ...
