[Interview] The Infinity Galaxy: First Evidence of a Direct Collapse Supermassive Black Hole?
How did supermassive black holes get so big so early? There are two main models for that, and JWST just got a huge boost for the one that suggests they can form via a direct collapse of gas clouds. How did the researchers pull the first observations of a potential birth of a SMBH? Finding out in this interview.
