Title: Radiation can never again dominate matter in a vacuum dominated universe

Abstract

We demonstrate that in a vacuum-energy-dominated expansion phase, surprisingly neither the decay of matter nor matter-antimatter annihilation into relativistic particles can ever cause radiation to once again dominate over matter in the future history of the Universe.

  • We test a cosmological model which the only component is a pressureless fluid with a constant bulk viscosity as an explanation for the present accelerated expansion of the universe. We classify all the possible scenarios for the universe predicted by the model according to their past, present and future evolution and we test its viability performing a Bayesian statistical analysis using the SCP ''Union'' data set (307 SNe Ia), imposing the second law of thermodynamics on the dimensionless constant bulk viscous coefficient {zeta}-tilde and comparing the predicted age of the universe by the model with the constraints coming from themore » oldest globular clusters. The best estimated values found for {zeta}-tilde and the Hubble constant H{sub 0} are: {zeta}-tilde = 1.922{+-}0.089 and H{sub 0} = 69.62{+-}0.59 (km/s)Mpc{sup -1} with a {chi}{sup 2}{sub min} = 314 ({chi}{sup 2}{sub d.o.f} = 1.031). The age of the universe is found to be 14.95{+-}0.42 Gyr. We see that the estimated value of H{sub 0} as well as of {chi}{sup 2}{sub d.o.f} are very similar to those obtained from {Lambda}CDM model using the same SNe Ia data set. The estimated age of the universe is in agreement with the constraints coming from the oldest globular clusters. Moreover, the estimated value of {zeta}-tilde is positive in agreement with the second law of thermodynamics (SLT). On the other hand, we perform different forms of marginalization over the parameter H{sub 0} in order to study the sensibility of the results to the way how H{sub 0} is marginalized. We found that it is almost negligible the dependence between the best estimated values of the free parameters of this model and the way how H{sub 0} is marginalized in the present work. Therefore, this simple model might be a viable candidate to explain the present acceleration in the expansion of the universe.« less
  • Heavy neutrinos having a mass of 10 keV or more can take an interesting role in galaxy formation. They can be consistent with the energy density of the present universe if their number density is accordingly small. This is possible even without having lepton flavor-violating neutrino decays if the neutrinos have interactions mediated by light scalars so that they decouple after they become nonrelativistic. We discuss the bounds on the properties of such scalars. A specific model is discussed where these bounds can be realized.
  • The clustering properties and large-scale motion in a standard neutrino-pancake model are shown to be consistent with observation for a steep primordial density perturbation spectrum. The autocorrelation properties of QSO Ly..cap alpha.. absorbers are shown to be consistent with the behavior of matter in numerical simulations of neutrino-dominated universe. The importance of beginning simulations at a highly linear stage is emphasized. Subject headings: cosmology-neutrinos
  • We present the results of numerical simulations of nonlinear gravitational clustering in universe dominated by weakly interacting, ''cold'' dark matter (e.g., axions or photinos). These studies employ a high resolution N-body code with periodic boundary conditions and 32,768 particles; they can accurately represent the theoretical initial conditions over a factor of 16 in length scale. We have followed the evolution of ensembles of models with ..cap omega.. = 1 and ..cap omega.. < 1 from the initial conditions predicted for a ''constant curvature'' primordial fluctuation spectrum.
  • The hypothesis that galaxies form from rare fluctuations in a universe dominated by cold, weakly interacting dark matter is shown to be in reasonable accord with most observed properties of the distribution of galaxies. The normalization of the primordial power spectrum is chosen to reproduce the observed coherence length of the galaxy distribution. In particular, we compute the rms galaxy peculiar velocities, the quadrupole anisotropy in the microwave background radiation induced by potential fluctuations, and the galaxy luminosity and multiplicity functions. We find that pancake-like structures develop which are associated with scales that have recently become nonlinear. Application is mademore » to calculate the baryonic mass fraction not incorporated into galaxies. Inclusion of a threshold effect is necessary in order to suppress the low-sigma fluctuations from forming galaxies. For illustrative purposes, we consider a threshold in redshift at z = 3, associated with the peaking of quasar activity and presumed reionization of the intergalactic medium. This assumption allows us to determine the luminosity function of forming objects on all scales. Consideration of the cooling function appropriate to a primordial cloud allows us to identify all objects of scale greater than 10/sup 7/ M/sub sun/ and below 10/sup 12/ M/sub sun/ with galaxies. The only potential difficulty encountered is that our relatively crude statistical treatment predicts a number density of low-luminosity galaxies that considerably exceeds most extrapolations of the bright-galaxy luminosity function.« less
