The structure of cold dark matter halos
JF Navarro - Symposium-international astronomical union, 1996 - cambridge.org
High resolution N-body simulations show that the density profiles of dark matter halos
formed in the standard CDM cosmogony can be fit accurately by scaling a simple “universal” …

The cosmological constant and dark energy
PJE Peebles, B Ratra - Reviews of modern physics, 2003 - APS
Physics welcomes the idea that space contains energy whose gravitational effect
approximates that of Einstein's cosmological constant, Λ; today the concept is termed dark …

Supersymmetric dark matter
G Jungman, M Kamionkowski, K Griest - Physics Reports, 1996 - Elsevier
There is almost universal agreement among astronomers that most of the mass in the
Universe and most of the mass in the Galactic halo is dark. Many lines of reasoning suggest …

[HTML][HTML] Observational evidence for primordial black holes: A positivist perspective
BJ Carr, S Clesse, J Garcia-Bellido, MRS Hawkins… - Physics Reports, 2024 - Elsevier
We review numerous arguments for primordial black holes (PBHs) based on observational
evidence from a variety of lensing, dynamical, accretion and gravitational-wave effects. This …
