Lyman Alpha Absorber Correlations and the Bias of the Lyman Alpha Forest
BIAS THE Lyman Alpha Forest
font style='font-size:12px;'>
2014/12/26
Lyman alpha absorber correlations contain information about the underlying density distribution associated with a particular class of absorbers. As such, they provide an opportunity to independently m...
AzTEC Millimetre Survey of the COSMOS field - II. Source count overdensity and correlations with large-scale structure
galaxies submillimeter gravitational lensing
font style='font-size:12px;'>
2014/12/22
We report an overdensity of bright submillimetre galaxies (SMGs) in the 0.15 deg2 AzTEC/COSMOS survey and a spatial correlation between the SMGs and the optical-IR galaxy density at z≲ 1.1. This...
Improved Constraints on Type Ia Supernova Host Galaxy Properties using Multi-Wavelength Photometry and their Correlations with Supernova Properties
Improved Constraints Supernova Galaxy Properties Multi-Wavelength Photometry Correlations Supernova Properties
font style='font-size:12px;'>
2011/10/18
We improve estimates of stellar mass and mass-weighted average age of Type Ia supernova (SN Ia) host galaxies by combining UV and near-IR photometry with optical photometry in our analysis. Using 206 ...
Stellar mass-to-light ratio gradients in galaxies: correlations with mass
dark matter – galaxies : evolution – galaxies : galaxies : general –galaxies : elliptical and lenticular, cD.
font style='font-size:12px;'>
2011/10/9
We analyze the stellar mass-to-light ratio (M/L) gradients in a large sample of local galaxies taken from the Sloan Digital Sky Survey, spanning a wide range of stellar masses and morphological types....
Directional correlations between UHECRs and neutrinos observed with IceCube

2010/11/10
Ultra-high energy cosmic rays (UHECR) above an energy threshold of tens of EeV might undergo only small deflections due to interstellar magnetic fields. Their arrival directions would then point to re...
Studies of Diffuse Interstellar Bands. V. Pairwise Correlations of Eight Strong DIBs and Neutral Hydrogen, Molecular Hydrogen, and Color Excess
ISM lines and bands − ISM molecules
font style='font-size:12px;'>
2010/11/15
We establish correlations between equivalent widths of eight diffuse interstel-lar bands (DIBs), and examine their correlations with atomic hydrogen, molec-ular hydrogen, and EB−V . The DIBs are...
Hanbury Brown-Twiss interferometry and second-order correlations of inflaton quanta
Hanbury Brown-Twiss interferometry second-order correlations
font style='font-size:12px;'>
2010/11/11
The quantum theory of optical coherence is applied to the scrutiny of the statistical
properties of the relic inflaton quanta. After adapting the description of the quantized scalar
and tensor modes...

Ultraviolet Divergences Cosmological Correlations
font style='font-size:12px;'>
2010/11/16
A method is developed for dealing with ultraviolet divergences in calculations of cosmological correlations, which does not depend on dimensional regularization. An extended version of the WKB approxi...

2010/11/9
The correlations between the rest frame peak of the F spectrum of GRBs (Epeak) and their
isotropic energy (Eiso) or luminosity (Liso) could have several implications for the understanding of the GR...

font style='font-size:12px;'>
2010/10/18
We review observations and gravitational lensing theory related to the magnification of background QSOs by intervening overdensities, and the induced cross-correlation between sources and foreground g...
