Recently, some efforts focus on differentiating dark energy and modified gravity with the growth function δ(z). In the literature, it is useful to parameterize the growth rate f ≡ d ln δ/d ln a = Ω γ m with the growth index γ. In this note, we consider the general DGP model with any Ω k . We confront the growth index of DGP model with currently available growth rate data and find that the DGP model is still consistent with it. This implies that more and better growth rate data are required to distinguish between dark energy and modified gravity.

“…However, if we assume that the length scale of the perturbations is much smaller than the Hubble radius then a Newtonian treatment of the perturbations is expected to be valid (e.g. Peebles 1980). Throughout this paper we will consider perturbations in the collisionless cold dark matter (CDM) distribution only.…”

Abstract. We study an approach to the formation of large-scale structure in the universe based on the description of a self-gravitating fluid in terms of a Schrödinger equation coupled to the usual Poisson equation. This approach has a number of promising features, but also some peculiarities. In this exploratory paper we discuss the behaviour of perturbations of the Schrödinger-Poisson system in simple one-dimensional configurations and compare the results with more conventional approaches: linear perturbation theory of the fluid equations and the Zeldovich approximation. The results demonstrate that our approach furnishes a useful addition to the repertoire of analytical techniques available for the description of cosmological perturbations, but that there are a number of subtleties to be faced when this method is applied in practice. In particular, care must be taken in choosing appropriate values for the effective Planck constant in the theory.PACS numbers: 95.35.+d, 98.65.Dx, Submitted to: J. Cosmol. Astropart. Phys.

“…Many estimators, namely two-point correlation functions [1][2][3][4], have been proposed and widely used to search for clustering of objects and to measure deviation from isotropy of angular distributions. A non-differential variant of such an estimators is widely used for small data set of points [5][6][7][8][9].…”

We present a novel method, based on a multiscale approach, for detecting anisotropy signatures in the arrival direction distribution of the highest energy cosmic rays. This method is catalog independent, i.e. it does not depend on the choice of a particular catalog of candidate sources, and it provides a good discrimination power even in presence of contaminating isotropic background. We present applications to simulated data sets of events corresponding to plausible scenarios for events detected, in the last decades, by world-wide surface detector-based observatories for charged particles.
