Dark matter velocity dispersion effects on CMB and matter power spectra

Oliver F. Piattella, +3 more
- 09 Feb 2016 - 
TL;DR: In this paper, the effects of velocity dispersion of dark matter particles on the CMB TT power spectrum and on the matter linear power spectrum were investigated using a modified CAMB code.
Journal ArticleDOI

Dark matter effects in vacuum spacetime

Luca Rizzi, +5 more
- 15 Jul 2010 - 
TL;DR: In this paper, the authors analyze a toy model describing an empty spacetime in which the motion of a test mass and the trajectories of photons evidence the presence of a continuous and homogeneous distribution of matter; however, since the energy-momentum tensor vanishes, no real matter or energy distribution is present at all.
Journal ArticleDOI

Is the continuous matter creation cosmology an alternative to ΛCDM

Júlio C. Fabris, +3 more
- 17 Jun 2014 - 
TL;DR: In this paper, the authors revisited the matter creation cosmology, including the evolution of baryons and dark matter particles, and they showed that the creation process affects only dark matter and not Baryons.
Journal ArticleDOI

CMB-Galaxy correlation in Unified Dark Matter Scalar Field Cosmologies

Daniele Bertacca, +8 more
- 23 Mar 2011 - 
TL;DR: In this article, the cross-correlation between the CMB and the large-scale structure (LSS) of the universe in Unified Dark Matter (UDM) scalar field cosmologies is analyzed.
