It’s the JWST’s turn to look for an intermediate mass black hole

Intermediate mass black holes (IMBH), if they exist, have between about 100 and 1,000 solar masses, placing them in between stellar black holes and supermassive black holes. But while there’s plenty of evidence for both stellar mass black holes and supermassive black holes, the evidence for IMBHs isn’t as convincing. There are many candidates, but there’s no wide agreement on any of them. Yet our theories of black holes show there should be something in between stellar black holes and supermassive black holes, and IMBHs could be the missing link.
