ABSTRACT The Sloan Digital Sky Survey III (SDSS-III) presents the first spectroscopic data
from the Baryon Oscillation Spectroscopic Survey (BOSS). This ninth data release (DR9) of …

For the last 100 years, General Relativity (GR) has taken over the gravitational theory mantle
held by Newtonian Gravity for the previous 200 years. This article reviews the status of GR in …

Recent work has shown that the local non-Gaussianity parameter f NL induces a scale
dependent bias, whose amplitude is growing with scale. Here we first rederive this result …

We present a test of different error estimators for two-point clustering statistics, appropriate
for present and future large galaxy redshift surveys. Using an ensemble of very large dark …

We develop a new approach to study the nonlinear evolution in the large-scale structure of
the Universe both in real space and in redshift space, extending the standard perturbation …

The dark energy dominated warm dark matter (WDM) model is a promising alternative
cosmological scenario. We explore large-scale structure formation in this paradigm. We do …

The XENON10 experiment at the Gran Sasso National Laboratory uses a 15 kg xenon dual
phase time projection chamber (XeTPC) to search for dark matter weakly interacting …

Mounting observational data confirm that about 73% of the energy density consists of dark
energy which is responsible for the current accelerated expansion of the Universe. We …

A simple way to accommodate dark matter is to postulate the existence of a hidden sector.
That is, a set of new particles and forces interacting with the known particles predominantly …

We explore nonlocally modified models of gravity, inspired by quantum loop corrections, as
a mechanism for explaining current cosmic acceleration. These theories enjoy two major …
