We focus on some features in the correlations patterns, in particular, of density-density correlations. The application to the study of the Hawking signal in the formation of acoustic black hole-like configurations is also discussed. %R 10.1103/PhysRevD.83.124016 %U http://arxiv.org/abs/1004.4876 %U https://doi.org/10.1103/PhysRevD.83.124016 %P 124016-14pp
