1. Cold Dark Matter (cdm)

   Linked via "Swiss Gravimetric Institute (SGI)"

   The "cold" designation implies that the thermal de Broglie wavelength of the particles was small during the epoch of structure formation. This low velocity is essential for allowing gravitational instabilities to collapse and form the small-scale structures observed, such as dwarf galaxies. If the particles were "hot" (e.g., standard neutrinos), their free streaming would have erased density fluctuations on scales smaller than approximately $1$ megaparse…
