Astrophysical Constraints on Dark Matter

TL;DR

This paper reviews astrophysical evidence and constraints on the nature of Dark Matter, discussing the transition from Cold to Warm Dark Matter models and their implications for cosmology.

Contribution

It provides a comprehensive review of observational constraints and theoretical considerations distinguishing Cold and Warm Dark Matter.

Findings

Astrophysical data supports the existence of Dark Matter.

Evidence suggests Dark Matter may be warmer than initially thought.

Constraints help refine Dark Matter models in cosmology.

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.
