Gas swirls around a black hole due to its intense gravity, forming an accretion disk. These accretion disks, being among the most efficient energy conversion mechanisms in the universe, emit light ...

The problem is that black holes don't look like they're supposed to look according to the theory. In theory, the accretion disks should be flat, but astronomical observation shows that disks are ...

This helped to constrain the size of the accretion disk as the team could see the hydrogen line comes from a distance of 16.77 light-days from the central supermassive black hole, while the oxygen ...

An accretion disk, as the name implies, is a disk-shaped gas that spirals inwards towards a central black hole. There is a great interest in studying the unique and extreme properties of black holes.

A comprehensive review has reassessed the observational properties and spectral states of ULXs, highlighting how multiwavelength campaigns inform models of black hole and neutron star accretion [1].
