Galaxies’ clustering generalized theory

Physics of the Dark Universe, 2021
Abstract In the present work we present, for the first time ever, the exact configuration integral entering the partition function Z that allows for a statistical mechanics treatment of galactic clustering. Thus, the general distribution function and the general clustering parameter for point mass systems is obtained from a grand canonical ...

Generalized theory of clustering of extended galaxies with core halos

Physics of the Dark Universe, 2021
Abstract We discuss the clustering of core halo-galaxies of radius predicted by gravitational lensing. We appeal to a blend of recent (1) mathematical results and (2) statistical mechanics techniques. The exact configurational integrals of extended galaxies is evaluated together with the pertinent partition functions, the corresponding thermodynamics,

Second-generation galaxies in merging clusters?

Astronomical & Astrophysical Transactions, 2004
We consider gas-dynamics phenomena in merging clusters of galaxies. According to X-ray observations, merger shocks involve considerable baryonic masses and compress them into large-scale gaseous layers. The internal structure of the layers includes vorticity and magnetic fields generated in the process of the layer formation and evolution.
