The redshift evolution of the X-ray emission of galaxies is an excellent diagnostic for the cosmological evolution of compact object populations and testing models for binary stellar evolution. These in turn are key ingredients for understanding grav

Spherical collapse predicts that a single value of the turnaround density (average matter density within the scale on which a structure detaches from the Hubble flow) characterizes all cosmic structures at the same redshift. It has been recently show

We use N-body simulations to examine whether a characteristic turnaround radius, as predicted from the spherical collapse model in a $\rm {\Lambda CDM}$ Universe, can be meaningfully identified for galaxy clusters, in the presence of full three-dimen
