Acesso em: 06 jul. 2022.2470-0010http://www.repositorio.ufop.br/jspui/handle/123456789/16010We calculate the skewness (the third moment S3) of matter distribution in dynamical dark energy cosmologies. We pay particular attention to the impact of dark energy perturbations on this quantity. There is indeed a clear signature of dark energy perturbations on this quantity. By properly allowing dark energy perturbations we show that their impact on S3 is strong enough (a factor ∼3 greater) to easily discriminate between clustering and nonclustering dark energy cosmologies. This indicates that high order statistics of the cosmic density field are useful to the study of dark energy models and are potentially able to rule out clustering dark energy cosmologies.en-USrestritoArtigo publicado em periodicohttps://journals.aps.org/prd/abstract/10.1103/PhysRevD.101.023518https://doi.org/10.1103/PhysRevD.101.023518
