6. No.

Per the article, those are supermassive black holes (SMBH), not stellar mass black holes. SMBHs form the gravitational heart/center of most galaxies, including our own, and formed in the early stages of the universe (although current hypotheses aren’t quite adequate for explaining exactly how).

Stellar mass black holes, are the kind that you will find all around the galaxy, as the creation of those are the result of massive stars exploding in a supernova, and in doing so, causes an implosion/compression of the core into a black hole. Stellar mass black holes usually “weigh” between 10 to several hundred solar masses. That compared to SMBHs which come in at millions to billions of solar masses.

So far, there hasn’t been much in terms of finding black holes in the mass category between the two.
