====== Description ======
This group covers properties of dark matter that can be uniquely probed by cosmological and astrophysical observations.  Techniques include measurements of the cosmological distribution of dark matter, as well as studies of astrophysical objects in extreme environments. Examples of dark matter models probed through these techniques are warm dark matter, self-interacting dark matter, ultra-light axions, and primordial black holes.

====== Solicited White Paper Topics ======

Through a series of discussions, CF03 has arrived at a list of 6 solicited white papers. CF03 is happy to accept additional contributed white papers, but we encourage people to join these efforts when possible.

  - Dark matter physics from halo measurements
  - Primordial Black Holes & Gravitational Waves
  - Numerical simulations and systematics
  - Connecting dark matter to early universe physics
  - Dark matter physics in extreme astrophysical environments
  - Facilities for cosmic probes of dark matter physics
