The James Webb “Little Red Dots” and the Black Hole Star
I’m not sure if there has been too much discussion about it but as someone who has been following the saga of the “little red dots”, the extremely bright and extremely distant objects discovered by the JWST, there have been some interesting developments in early universe cosmology
At first, these red objects were thought to be very early galaxies shrouded in dust, and this caused some issues because the models of galaxy formation didn’t account for them being this large this early
But thankfully, we caught a glimpse of a specific red dot that was sitting directly behind a massive galactic supercluster. This created a lensing effect that amplified the object and allowed us to perform spectrographic analysis revealing that it is most likely a massive cloud of gas surrounding an early supermassive black hole
In a similar manner to the way fusion pressure can hold up a star, a black hole could theoretically hold up a glowing gas envelope that is 67 AU across. This kind of object would be so bright it would outshine a galaxy and have a habitable zone 2 light months away. You’d have other problems to deal with like the insane radiation and 1-7 million year lifespan though. This also potentially solves the problem of where the supermassives came from.
What are other people’s thoughts on the little red dots? Thought it would be interesting having a discussion about it because it seems like kind of a big deal in black hole physics
