Measuring the halo mass of z similar to 3 damped Ly alpha absorbers from the absorber-galaxy cross-correlation
high-redshift absorption lines
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...
Accelerating Radio Astronomy Cross-Correlation with Graphics Processing Units
Radio astronomy Graphics Processing Unit Signal Processing Correlation
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...

The Spatial Clustering ROSAT All-Sky Survey AGNs II
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
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...
