چکیده
We investigate two important questions about the use of the nonextensive thermo-statistics (NETS) formalism in the context of nonlinear galaxy clustering in the Universe. Firstly, we define a quantitative criterion for justifying nonextensivity at different physical scales. Then, we discuss the physics behind the ansatz of the entropic parameter q(r). Our results suggest the approximate range where nonex-tensivity can be justified and, hence, give some support to the applicability of NETS to the study of large scale structures.

I show that advanced simulations of cosmological reionization are able to fit the observed data on the mean transmitted flux in the hydrogen Lyman-alpha line at z ∼ 6. At the same time, posteriori models can be constructed that also produce a large value (20%) for the Thompson scattering optical depth, consistent with the WMAP measurements. Thus, it appears that a consistent picture emerges in ...

Quantum model of homogeneous and isotropic universe predicts logarithmic-law dependence of coordinate distance to source on redshift z which is in good agreement with type Ia supernovae and radio galaxies observations for the redshift range z = 0.01 − 1.8. Comparison with phenomenological models with dark energy in the form of cosmological constant and without dark energy component is made. Flu...

Hughes & Gaztañaga (2001, see article in these proceedings) have presented realistic simulations to address key issues confronting existing and forthcoming submm surveys. An important aspect illustrated by the simulations is the effect induced on the counts by the sampling variance of the large-scale galaxy clustering. We find factors of up to ∼ 2 − 4 variation (from the mean) in the extracted ...
