Non-adiabatic dark fluid cosmology
W. S. Hipolito-Ricaldi, H. E. S. Velten, W. Zimdahl
We model the dark sector of the cosmic substratum by a viscous fluid with an equation of state , where is the fluid-expansion scalar and is the coefficient of bulk v…

Can a primordial magnetic field originate large-scale anomalies in WMAP data?
A. Bernui, W. S. Hipolito-Ricaldi
Several accurate analyses of the CMB temperature maps from the Wilkinson Microwave Anisotropy Probe (WMAP) have revealed a set of anomalous results, at large angular scales, that a…

Topological signatures in CMB temperature anisotropy maps
W. S. Hipolito-Ricaldi, G. I. Gomero
We propose an alternative formalism to simulate CMB temperature maps in CDM universes with nontrivial spatial topologies. This formalism avoids the need to explicitly compute th…
