Cosmic strings with interacting hot dark matter
P. P. Avelino, J. P. M. de Carvalho
Abstract
We compute the linear power spectrum of cosmic string sedeed fluctuations in the context of neutrinos with a strong self-interaction and show that it is very similar to that obtained in the context of `normal' neutrinos. We compare our results with observational data and show that for any value of the cosmological parameters h and Ω0 the interacting hot dark matter power spectrum requires a large scale dependent biasing parameter.
