Absence of Correlation between the Solar Neutrino Flux and the Sunspot Number
Solar Neutrino Flux Sunspot Number
font style='font-size:12px;'>
2015/8/20
There exists a considerable amount of research claiming a puzzling anticorrelation between the
neutrino detection rate at the Homestake experiment and indicators of solar activity such as the sunspot...
The galaxy angular correlation functions and power spectrum from the Two Micron All Sky Survey
general statistics
font style='font-size:12px;'>
2014/12/24
We calculate the angular correlation function of galaxies in the Two Micron All Sky Survey. We minimize the possible contamination by stars, dust, seeing, and sky brightness by studying their cross co...
Measuring the halo mass of z similar to 3 damped Ly alpha absorbers from the absorber-galaxy cross-correlation
high-redshift absorption lines
font style='font-size:12px;'>
2014/12/24
We test the reliability of a method to measure the mean halo mass of absorption-line systems such as damped Lyα absorbers (DLAs). The method is based on measuring the ratio of the cross-correlation be...
Spatial correlation between submillimetre and Lyman-alpha galaxies in the SSA 22 protocluster
submillimetre Lyman-alpha galaxies
font style='font-size:12px;'>
2014/12/23
Lyman- emitters are thought to be young, low-mass galaxies with ages of 108 yr (refs 1, 2). An overdensity of them in one region of the sky (the SSA 22 field) traces out a filamentary structure in the...
Accelerating Radio Astronomy Cross-Correlation with Graphics Processing Units
Radio astronomy Graphics Processing Unit Signal Processing Correlation
font style='font-size:12px;'>
2011/10/13
We present a highly parallel implementation of the cross-correlation of time-series data using graphics processing units (GPUs), which is scalable to hundreds of independent inputs and suitable for th...
Two generations in stellar complexes and associations in M 33 galaxy and their spatial correlation
generations stellar complexes associations galaxy spatial correlation
font style='font-size:12px;'>
2011/10/18
Massive stellar content of stellar complexes and associations in M 33 is studied combining deep UBV photometry from the Local Group Survey (Massey et al. 2006) and JHK photometry from the 2MASS. Two b...
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...
Herschel/HerMES: The X-ray - Infrared correlation for star-forming galaxies at z~1
X-ray - Infrared correlation star-forming galaxies
font style='font-size:12px;'>
2011/9/29
For the first time, we investigate the X-ray/infrared (IR) correlation for star-forming galaxies at z~1, using SPIRE submm data from the recently-launched Herschel Space Observatory and deep X-ray dat...
Her X-1: the positive cyclotron line energy / luminosity correlation
pulsars: individual: – stars: neutron – stars: binaries
font style='font-size:12px;'>
2011/9/28
Studies of some bright, super-Eddington transient pulsars show a negative correlation between the energy of the cyclotron resonance scattering feature (CRSF) and the bolometric luminosity. For Her X-1...
A Correlation Between Surface Densities of Young Stellar Objects and Gas in Eight Nearby Molecular Clouds
Stellar Objects Gas Nearby Molecular Clouds
font style='font-size:12px;'>
2011/9/28
We report the discovery and characterization of a power law correlation between the local surface densities of Spitzer-identified, dusty young stellar objects and the column density of gas (as traced ...

The Spatial Clustering ROSAT All-Sky Survey AGNs II
font style='font-size:12px;'>
2011/1/11
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
font style='font-size:12px;'>
2010/11/11
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
