virialization

virialization

(vÿ-ree-ăl-i-zay -shŏn) The way in which dissipative physics intervenes in the gravitational collapse of a body (e.g. a cluster of galaxies) to convert the kinetic energy of the collapse into random motions of the constituent members.

Before simulating the gravitational interaction between the initial dwarfs and the host galaxy, they were simulated separately only under their self-gravity to eliminate spurious numerical effects caused at the numerical generation of each object (virialization).
Figure 3 shows the results of the virialization of the dwarf galaxy surrounded by a halo of dark matter with initial conditions generated using ZENO.
Figure 4 shows the result of the virialization simulation of a disk galaxy with characteristics similar to those of the Milky Way.
