Breaking Halo Occupation Degeneracies with Marked Statistics
Martin White, Nikhil Padmanabhan
We show that a suitably defined marked correlation function can be used to break degeneracies in halo-occupation distribution modeling. The statistic can be computed on both 3D and…
Reconstructing Baryon Oscillations: A Lagrangian Theory Perspective
Nikhil Padmanabhan, Martin White, J. D. Cohn
Recently Eisenstein and collaborators introduced a method to `reconstruct' the linear power spectrum from a non-linearly evolved galaxy distribution in order to improve precision i…
Stellar SEDs from 0.3-2.5 Microns: Tracing the Stellar Locus and Searching for Color Outliers in SDSS and 2MASS
Kevin R. Covey, Zeljko Ivezic, David J. Schlegel +15
The Sloan Digital Sky Survey (SDSS) and Two Micron All Sky Survey (2MASS) are rich resources for studying stellar astrophysics and the structure and formation history of the Galaxy…
Cosmological Constraints from the SDSS Luminous Red Galaxies
M Tegmark, D Eisenstein, M Strauss +64
We measure the large-scale real-space power spectrum P(k) using luminous red galaxies (LRGs) in the Sloan Digital Sky Survey (SDSS) and use this measurement to sharpen constraints…
