Cosmic strings with self-interacting hot dark matter

P. P. Avelino, J. P. M. de Carvalho

Resumo
We compute the linear power spectrum of cosmic-string-seeded 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 Omega_0 the interacting hot dark matter power spectrum requires a scale-dependent biasing parameter.
