Growth of Structure                                                    Paper   ―   Key Figure

Redshift-space distortions in the galaxy clustering pattern can be used to extract the growth rate of structure over the redshift range 0 < z < 1.  The result can be compared to the predictions of cosmological models fit to the shape of the clustering pattern, normalized using the CMB.  This allows robust tests of Lambda-CDM and DGP cosmologies.

Intrinsic Alignments of Blue Galaxies                                                  Paper   

Intrinsic alignments of galaxy shapes with each other, and with the local density field, can contaminate lensing signal measurements at the level of a few percent, which will be important for the next generation of lensing surveys. These alignments also are a window into the process of galaxy formation, because they tell us how the larger scale density field influences the alignment of galaxies within their own dark matter halos. Current SDSS spectroscopic samples (particularly the LRGs) have given us a good understanding of these alignments for red galaxies, but comparable constraints do not currently exist for blue galaxies.http://lanl.arxiv.org/abs/0911.5347shapeimage_6_link_0
















Kinematics of Star-Forming Galaxies                                                 Paper   

Galaxies in WiggleZ Survey at z>1 are some of the most luminous objects to be found at these redshifts. Despite their high rates of star-formation the majority of these galaxies show ordered orbital motion. Resolved kinematics from integral field spectroscopy allow a detailed examination of the motion of the gas in these galaxies revealing turbulent disks with kiloparsec-size star-forming regions. http://lanl.arxiv.org/abs/1103.5265shapeimage_7_link_0

Baryon Acoustic Oscillations                                   Paper   ―   Key Figure

In this paper we measure the imprint of baryon acoustic oscillations in the galaxy clustering pattern at z=0.6, the highest redshift achieved to date.  The statistical significance of our detection of the acoustic peak in the correlation function is 3.2-sigma.  Our distance measurements, combined with the Sloan BAO data at lower redshifts, confirms the existence of dark energy with properties consistent with a cosmological constant.http://astronomy.swin.edu.au/~cblake/wigglez_bao_resubmitted.pdfprojects_files/bao.jpgshapeimage_8_link_0shapeimage_8_link_1
