Cosmological constraints on entropic cosmology with matter creation

نویسندگان

چکیده

We investigate entropic force cosmological models with the possibility of matter creation and energy exchange between bulk horizon a homogeneous an isotropic flat Universe. consider three different kinds entropy, Bekenstein's, non-extensive Tsallis-Cirto's quartic plus some phenomenological functional forms for rate to model put observational constraints on them. show that while most them are basically indistinguishable from standard $\Lambda$CDM scenario, Bekenstein proportional Hubble parameter is statistically highly favored over $\Lambda$CDM. As general result, we also find both Hawking temperature $\gamma$, which relates boundary Universe, $\Gamma(t)$, must be very small in order reproduce data.

Cosmological Constraints on Tachyon Matter

We examine whether tachyon matter is a viable candidate for the cosmological dark matter. First, we demonstrate that in order for the density of tachyon matter to have an acceptable value today, the magnitude of the tachyon potential energy at the onset of rolling must be finely tuned. For a tachyon potential V (T ) ∼ M4 P l exp(−T/τ), the tachyon must start rolling at T ≃ 60τ in order for the ...

Thermodynamics of cosmological matter creation.

A type of cosmological history that includes large-scale entropy production is proposed. These cosmologies are based on reinterpretation of the matter-energy stress tensor in Einstein's equations. This modifies the usual adiabatic energy conservation laws, thereby including irreversible matter creation. This creation corresponds to an irreversible energy flow from the gravitational field to the...

Cosmological constraints on Neutrino - Dark Matter interactions

I summarize the results of a recent analysis where the cosmological effects of interactions of neutrinos with cold Dark Matter (DM) is investigated. This interaction produces diffusion-damped oscillations in the matter power spectrum, analogous to the acoustic oscillations in the baryon-photon fluid. I discuss the bounds from the Sloan Digital Sky Survey on the corresponding opacity defined as ...

Gravitino Dark Matter and Cosmological Constraints

The gravitino is a promising candidate for cold dark matter. We study cos-mological constraints on scenarios in which the gravitino is the lightest supersymmetric particle and a charged slepton the next-to-lightest supersymmetric particle (NLSP). We obtain new results for the hadronic nucleosynthesis bounds by computing the 4-body decay of the NLSP slepton into the gravitino, the associated lep...

Constraints on Warm Dark Matter from Cosmological Reionization

We study the constraints that high-redshift structure formation in the universe places on warm dark matter (WDM) dominated cosmological models. We modify the extended Press-Schechter formalism to derive the halo mass function in WDM models. We show that our predictions agree with recent numerical simulations at low redshift over the halo masses of interest. Applying our model to galaxy formatio...
