This summer, I published two research papers with my collaborators about the growth of supermassive black holes. One of those research papers was about what processes cause SMBHs to spin at their maximum rates, and the subsequent effect on their galaxy’s. So in this video we’re going to dive into that research paper and I’ll explain what we found… Beckmann, Smethurst et al.
