Dark photons' at Big Bang's cosmic dawn could shine a light on dark matter

Interactions between dark matter and dark photons during a "missing chapter" cosmic history could shed light on one of the most troubling cosmic mysteries.

Wouldn't "dark photons" provide the means for "dark matter" to shed energy and cool off?

Doesn't that run counter to some of the explanations about why dark matter does not condense like ordinary matter, which are used to explain "dark matter halo" etc. needed to explain why it is distributed differently than regular matter in galaxies and smaller scale astronomy observables?

I am not suggesting they are wrong, but I have my doubts they are 100% correct. There is clear evidence for galaxies to have formed within only a few hundred million years of the big bang, and we are finding evidence that supermassive black holes already existed in the heart of many of these first galaxies, having read their paper, mathematically they need to play with it and take into account research published since they submitted their paper - which was in early 2024, only being published in November 2024, about 9 months after submission.

However, their work is elegant and the maths fit, but only with the data and assumtions they made or had available at that time, I suspect that in the coming years we will see a flury of similar work from the same team and other collaborators that will be based on the lastest data from JWST research into those first 500 million years.
