The mechanism for creating “dynamical gravastar” black hole mimickers also explains formation of “little red dots”

We argue that a high pressure phase transition of relativistic matter to a state with negative energy density, which leads to the formation of horizonless, globally unitary black hole mimickers, also gives rise to the appearance of “little red dots”. The energy source for the dots is the release of latent energy from the phase transition, and their excess redness is a result of this release taking place in a central region of exponentially small positive g 00 , and hence very high gravitational redshift.
