Abstract

We propose a non-Gaussianity test for gravitational wave backgrounds by combining data streams of multiple detectors. This simple method allows us to check whether a detected background is "smooth" enough to be consistent with an inflation-type background, or is contaminated by individually undetectable weak burst signals. The proposed test would be quite useful for the Big Bang Observer or DECIGO whose primary target is a background from inflation at 0.1-1Hz where gravitational wave bursts from supernovae of population III stars might become a troublesome foreground.

Bayesian analysis of the backreaction models

We present the Bayesian analysis of four different types of backreation models, which are based on the Buchert equations. In this approach, one considers a solution to the Einstein equations for a general matter distribution and then an average of various observable quantities is taken. Such an approach became of considerable interest when it was shown that it could lead to agreement with observations without resorting to dark energy. In this paper we compare the LambdaCDM model and the backreation models with SNIa, BAO, and CMB data, and find that the former is favoured. However, the tested models were based on some particular assumptions about the relation between the average spatial curvature and the backreaction, as well as the relation between the curvature and curvature index. In this paper we modified the latter assumption, leaving the former unchanged. We find that, by varying the relation between the curvature and curvature index, we can obtain a better fit. Therefore, some further work is still needed -- in particular the relation between the backreaction and the curvature should be revisited in order to fully determine the feasibility of the backreaction models to mimic dark energy.

A differential study of the oxygen abundances in the Galactic thin and thick disks

First results from a study into the abundance trends of oxygen in the Galactic thin and thick disks are presented. Oxygen abundances for 63 nearby F and G dwarf stars, based on very high resolution spectra ($R\sim215 000$) and high signal-to-noise ($S/N>400$) of the faint forbidden oxygen line at 6300 Å, have been determined. Our findings can be summarized as follows: {\bf 1)} at $\rm [Fe/H]<0$ the oxygen trends in the thin and thick disk are smooth and distinct, indicating their different origins, {\bf 2)} $\rm [O/Fe]$ for the thick disk stars show a turn-over at [Fe/H]$\sim -0.35$, indicating the peak of the enrichment from SNe type Ia to the interstellar medium, {\bf 3)} the thin disk stars show a shallow decrease going from $\rm [Fe/H] \sim -0.7$ to the highest metallicities with no apparent turn-over present indicating a more quiet star formation history, and {\bf 4)} $\rm [O/Fe]$ continues to decrease at $\rm [Fe/H]>0$ without showing the leveling out that previously has been seen.
