BlueDOGs Might Evolve From Little Red Dots

One of the most difficult parts of astronomy is understanding how time affects it. The farther away you look in the universe, the farther back you look in time. One way this complicates things is how objects might change over time. For example, a supermassive black hole at the center of a galaxy in the early universe might appear one way to our modern telescopes, but the same supermassive black hole might appear completely differently a few billion years later. Understanding the connection between the two objects would be difficult to say the least, but a new paper from researchers at the University of Science and Technology in South Korea describes one potential parallel, between the recently discovered “Little Red Dots” of the early universe and “BlueDOGs” of the slightly later universe.
