A Two-Tiered Correlation of Dark Matter with Missing Transverse Energy: Reconstructing the Lightest Supersymmetric Particle Mass at the LHC
Correlation Dark Matter Missing Transverse Energy Reconstructing Lightest Supersymmetric
font style='font-size:12px;'>
2011/10/18
We suggest that non-trivial correlations between the dark matter particle mass and collider based probes of missing transverse energy H_T^miss may facilitate a two tiered approach to the initial disco...
The Spatial Clustering of ROSAT All-Sky Survey AGNs II. Halo Occupation Distribution Modeling of the Cross Correlation Function
The Spatial Clustering ROSAT All-Sky Survey AGNs II

This is the second paper of a series that reports on our investigation of the clustering properties of AGNs in the ROSAT All-Sky Survey (RASS) through cross-correlation functions (CCFs) with Sloan Dig...
ISW-LSS cross-correlation in coupled Dark Energy models with massive neutrinos
cosmic microwave background cosmology: miscellaneous cosmology observations cosmology: theory cosmology: large-scale structure of universe
font style='font-size:12px;'>
2010/11/9
We provide an exhaustive analysis of the Integrated Sach–Wolfe effect (ISW) in the context of coupled Dark Energy cosmologies where a component of massive neutrinos is also present. We focus on the ef...
Li - O anti-correlation in NGC 6752: evidence for Li-enriched polluting gas
stars abundances – globular clusters individual NGC6752 – stars late-type

Context. Elemental correlations and anti-correlations are known to be present in globular clusters (GCs) owing to pollution by CNO cycled gas. Because of its fragility Li is destroyed at the temperatu...
Solar Flares and Coronal Mass Ejections: A Statistically Determined Flare Flux-CME Mass Correlation
Flares Coronal mass ejections
font style='font-size:12px;'>
2010/11/9
In an effort to examine the relationship between flare flux and corresponding CME mass, we temporally and spatially correlate all X-ray flares and CMEs in the LASCO and GOES archives from 1996 to 2006...
Large-angle correlation anomalies and odd-parity preference in CMB data
cosmic background radiation early universe methods: data analysis meth-ods: statistical

2010/11/9
Angular power spectrum of CMB anisotropy and two point angular point correlation possess some
equivalence. Noting this, we have investigated the association between the WMAP large-angle corre-lation ...
A Two-Point Correlation Function For Galactic Halo Stars

2010/11/12
We describe a correlation function statistic that quantifies the amount of spatial and kinematic substructure in the stellar halo.We test this statistic using model stellar halo realizations construct...
Star formation: statistical measure of the correlation between the prestellar core mass function and the stellar initial mass function
stars formation — stars luminosity function mass function — ISM clouds
font style='font-size:12px;'>
2010/11/11
We present a simple statistical analysis of recent numerical simulations exploring the correlation between the core mass function obtained from the fragmentation of a molecular cloud and the stellar m...

We study the cosmic microwave background (CMB) temperature fluctuations non-gaussianity due to the vector mode perturbations (Alfv\'en waves) supported by a stochastic cosmological magnetic field. We ...
Turbulent eddy-time-correlation in the solar convective zone
Solar and Stellar Astrophysics (astro-ph.SR)
font style='font-size:12px;'>
2010/12/31
Theoretical modeling of the driving processes of solar-like oscillations is a powerful way of understanding the properties of the convective zones of solar-type stars. In this framework, the descripti...
Testing a prediction of the merger origin of early-type galaxies: a correlation between stellar populations and asymmetry
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/29
One of the key predictions of the merger hypothesis for the origin of early-type (elliptical and lenticular) galaxies is that tidally-induced asymmetric structure should correlate with signatures of a...
