baryonic matter, and
missing baryon problem
(AKA missing mass problem):
"In cosmologies with Λ>&Lambda_0, dark energy emerges as the dominant factor
in this process -- suggesting that, as our Universe transitions towards Λ-domination,
dark energy eventually becomes the primary driver of baryon evacuation from massive haloes."

- missing baryon problem in halos
(see McGaugh et al. 2010).
The missing baryon problem in halos
is that the in
dark matter halos
the baryon fraction f=Ω_b/&Omega_(b-cosmic) < 1.
In galaxies
f=Ω_b/&Omega_(b-cosmic) < 0.03 and has
dark matter halos get bigger
f=Ω_b/&Omega_(b-cosmic) approaches 1 for the largest
galaxy clusters.
