Abstract

Astrophysics gives evidence for the existence of Dark Matter and puts constraints on its nature. The Cold Dark Matter model has become “standard” cosmology combined with a cosmological constant. There are indications that “Cold” Dark Matter could be “warmer” than initially discussed. This paper reviews the main information on the Cold/Warm nature of Dark Matter.
