SUMMARY
This discussion focuses on the concepts of thermalization and virialization of cold dark matter (CDM) components within galactic halos. It clarifies that thermalization refers to the process through which particles reach a state of statistical equilibrium in velocity distributions, while virialization indicates that the system adheres to the virial theorem, relating kinetic and potential energy. The transition from non-thermalized to thermalized states occurs over time, particularly after disturbances such as galaxy mergers, which can disrupt the equilibrium described by the virial theorem.
