These two sources had low temperature disk components, which was interpreted as possible evidence for the presence of an intermediate-mass black hole. However, while the low-energy emission can be modelled as a low-temperature disk, the high-energy emission is at odds with the intermediate-mass black hole hypothesis.
These two sources had components on their disks at low temperatures, which suggested that there might be an intermediate-mass black hole. However, while the low-energy radiation can be explained as coming from a low-temperature disk, the high-energy radiation is inconsistent with the idea of an intermediate-mass black hole.
