Can neutrino viscosity drive the late time cosmic acceleration ?

چکیده
In this paper it has been shown that the neutrino bulk viscous stresses can give rise to the late time acceleration of the universe. It is found that a number of spatially flat FRW models with a negative deceleration parameter can be constructed using neutrino viscosity and one of them mimics a ΛCDM model. This does not require any exotic dark energy component or any modification of gravity.

Active Galactic Nuclei as High-Energy Neutrino Sources
Active galactic nuclei (AGN), which are powered by accretion of mass onto supermassive black holes (SMBHs) at the center of their host galaxies and/or the rotational energy of SMBHs, are the most luminous persistent sources of electromagnetic radiation in the Universe. They have also been of interest as powerful high-energy cosmic-ray accelerators (CRs), including ultrahigh-energy cosmic rays (...
متن کاملCosmic Acceleration and Modified Gravitational Models ∗
There is now overwhelming observational evidence that our Universe is accelerating in its expansion. I discuss how modified gravitational models can provide an explanation for this observed late-time cosmic acceleration. We consider specific lowcurvature corrections to the Einstein-Hilbert action. Many of these models generically contain unstable de Sitter solutions and, depending on the parame...
متن کاملViscosity-Induced Crossing of the Phantom Barrier
We show explicitly, by using astrophysical data plus reasonable assumptions for the bulk viscosity in the cosmic fluid, how the magnitude of this viscosity may be high enough to drive the fluid from its position in the quintessence region at present time t = 0 across the barrier w = −1 into the phantom region in the late universe. The phantom barrier is accordingly not a sharp mathematical divi...
متن کاملBulk Viscosity, Decaying Dark Matter, and the Cosmic Acceleration
We discuss a cosmology in which cold dark-matter particles decay into relativistic particles. We argue that such decays could lead naturally to a bulk viscosity in the cosmic fluid. For decay lifetimes comparable to the present hubble age, this bulk viscosity enters the cosmic energy equation as an effective negative pressure. We investigate whether this negative pressure is of sufficient magni...
متن کاملMultimessenger search for point sources: ultra-high energy cosmic rays and neutrinos
The origin of ultra-high energy cosmic rays (UHECRs) and neutrinos is still a mystery. Hadronic acceleration theory suggests that they should originate in the same sources (astrophysical or cosmological), together with gammarays. While gamma-rays have been linked to astrophysical sources, no point source of UHECRs or neutrinos have been found so far. In this paper, the multimessenger combinatio...
