             abstract = "Although the theoretical understanding of the nonlinear 
                         gravitational clustering has greatly advanced in the last decades, 
                         in particular by the outstanding improvement on numerical N-body 
                         simulations, the physics behind this process is not fully 
                         elucidated. The main goal of this work is to investigate the 
                         presence of turbulent-like and extreme event dynamics in the 
                         formation of structures, galaxies and clusters of galaxies, by the 
                         action of gravity alone. We use simulation data from the Virgo 
                         Consortium (simulation box of side 239.5 h\−1 Mpc, and N = 
                         2563 particles), in ten redshift snapshots (from z = 0 to 10). 
                         From this we identify galaxy-sized and cluster-sized dark matter 
                         haloes, by using a FoF algorithm and applying a boundedness 
                         criteria, and study the gravitational potential energy spectra. We 
                         find that the galaxy-sized haloes energy spectrum follows closely 
                         a Kolmogorov power law, similar to the behaviour of dynamically 
                         turbulent processes in fluids. We also find that energy histograms 
                         are well described by a Generalized Extreme Value distribution. 
                         Extreme events are those phenomena described by the tails of the 
                         probability distribution, like the intense and intermittent bursts 
                         of found in turbulent phenomena. These results mean that the 
                         gravitational clustering of dark matter may admit a turbulent-like 
                         representation.",
