Nature and distribution of dark matter. II - Binaries, groups, and clusters

The mass-radius relationship for aggregates of galaxies (binaries, small groups, and clusters) is studied using a simple best-fit analysis. It is found that the binaries are just two galaxies, each with an individual isothermal dark matter halo, moving under mutual gravitational attraction. Power-la...

description The mass-radius relationship for aggregates of galaxies (binaries, small groups, and clusters) is studied using a simple best-fit analysis. It is found that the binaries are just two galaxies, each with an individual isothermal dark matter halo, moving under mutual gravitational attraction. Power-law relations to describe the groups and clusters are examined, suggesting that two components exist in dark matter: one clustered around the galaxies, and one distributed smoothly. (R.B.)
