I have been interested in how neutrinos arrange themselves around gravitational potentials. However, I found contradictory claims and I would like to clarify this
After reading a bit into this paper (https://arxiv.org/pdf/2301.12430) I contacted the authors of it, and they told me that no neutrinos would he gravitationally bound even to the largest structures like superclusters.
However, then, I found a bunch of other papers claiming how would relic neutrinos (that would not be longer relativistic due to the redshift suffered to their momentun by the expansion of the universe):
https://arxiv.org/abs/2207.02860
https://arxiv.org/abs/1910.13388
https://arxiv.org/abs/2306.16444
Then, what is happening? Aren't they contradicting each other? Are there neutrinos gravitationally bound to massive structures or not?
