Título: The two modes puzzle: The impact of Self-Interacting Neutrinos in the Large Scale Structure of the Universe
Resumo: According to several analyses, a cosmological scenario in which neutrinos strongly interact among them, delaying their free-streaming until close to the epoch of matter-radiation equality, can offer a good fit to the CMB and BAO data. This scenario, which significantly deviates from the standard picture, predicts sizable changes in the linear power spectrum and could produce substantial changes in the Large Scales Structure (LSS) of the Universe. Yet, it is still unknown if the strongly self-interacting neutrinos can also offer a good fit for LSS data. Aiming to supply this gap, we investigate, in a CMB-independent fashion, the compatibility of the self-interacting neutrinos with the Full Shape of the galaxy power spectrum. Our analysis demonstrates that the strongly self-interacting neutrino cosmology is consistent with galaxy power spectrum data.
