Galaxy Angular Clustering Evolution in the SDSS Co-Add Imaging Data.
Doctoral Dissertation, University of Pittsburgh.
(Unpublished)
Abstract
We study the evolution of the angular clustering of galaxies as a function of redshift, luminosity, and type. We utilize redshift estimates computed from broadband photometry, so we require precise flux measurements. For this reason, we chose the SDSS co-added imaging data set from stripe 82 and obtained 1% error photometry with a custom image processing pipeline. We measured the angular clustering of galaxies w(theta) and inverted it to obtain the real space correlation function xi(r), which we fit as a power law with parameters r0 and gamma. Finally, we use our measured xi(r) fits to constrain galaxy formation models and find that luminous galaxies are found in higher mass dark matter halos, in agreement with theory and previous results in the field.
