Model-Independent Measurement of the Primordial Power Spectrum
Yun Wang, David N. Spergel, Michael A. Strauss
In inflationary models with minimal amount of gravity waves, the primordial power spectrum of density fluctuations, , together with the basic cosmological parameters, com…
Spectroscopy of Quasar Candidates from SDSS Commissioning Data
Xiaohui Fan, Michael A. Strauss, James Annis +9
The Sloan Digital Sky Survey has obtained images in five broad-band colors for several hundred square degrees. We present color-color diagrams for stellar objects, and demonstrate…
Large-Scale Flows As A Cosmological Probe
Michael A. Strauss, Michael Blanton
We review the use of peculiar velocities of galaxies as a probe of cosmological models. We put particular emphasis on comparison of the peculiar velocity and density fields, focuss…
The Supergalactic Plane revisited with the Optical Redshift Survey
O. Lahav, B. X. Santiago, A. M. Webster +4
We re-examine the existence and extent of the planar structure in the local galaxy density field, the so-called Supergalactic Plane (SGP). This structure is studied here in three d…
SHELLFLOW: The First Homogeneous All-Sky TF Survey at 6000 km/s
S. Courteau, J. Willick, M. Strauss +2
We present a new optical Tully-Fisher (TF) investigation for a complete, full-sky sample of 297 Sb-Sc spirals with redshifts between 4500 and 7000 km/s. The survey was specifically…
Constraining the Dark Matter Distribution With Large-Scale Structure Observations
Michael A. Strauss, Michael Blanton
We discuss the use of galaxies to trace the large-scale structure of the universe and thereby to make cosmological inferences. We put special emphasis on our lack of knowledge abou…
