Halo-model Analysis of the Clustering of Photometrically Selected Galaxies from SDSS (2009)

Ross, Ashley J, Brunner, Robert J.

We measure the angular 2-point correlation functions of galaxies in a volume limited, photometrically selected galaxy sample from the fifth data release of the Sloan Digital Sky Survey. We split the...

A Cross-Correlation Analysis of Mg II Absorption Line Systems and Luminous Red Galaxies from the SDSS DR5 (2009)

Lundgren, Britt F., Brunner, Robert J., York, Donald G., Ross, Ashley J., Quashnock, Jean M., Myers, Adam D., ...

We analyze the cross-correlation of 2,705 unambiguously intervening Mg II (2796,2803A) quasar absorption line systems with 1,495,604 luminous red galaxies (LRGs) from the Fifth Data Release of the...

Normalization of the Matter Power Spectrum via Higher-Order Angular Correlations of Luminous Red Galaxies (2008)

Ross, Ashley J., Brunner, Robert J., Myers, Adam D.

We present a novel technique to measure $\sigma_8$, by measuring the dependence of the second-order bias of a density field on $\sigma_8$ using two separate techniques. Each technique employs...

Higher-Order Angular Galaxy Correlations in the SDSS: Redshift and Color Dependence of non-Linear Bias (2007)

Ross, Ashley J., Brunner, Robert J., Myers, Adam D.

We present estimates of the N-point galaxy, area-averaged, angular correlation functions $\bar{\omega}_{N}$($\theta$) for $N$ = 2,...,7 for galaxies from the fifth data release of the Sloan Digital...

Precision Measurements of Higher-Order Angular Galaxy Correlations Using 11 Million SDSS Galaxies (2006)

Ross, Ashley J., Brunner, Robert J., Myers, Adam D.

We present estimates of the N-point galaxy area-averaged angular correlation functions wN for N = 2,...,7 from the third data release of the Sloan Digital Sky Survey (SDSS). The sample was selected...
