Constraining Anisotropic Baryon Oscillations
Nikhil Padmanabhan, Martin White
We present an analysis of anisotropic baryon acoustic oscillations and elucidate how a mis-estimation of the cosmology, which leads to incorrect values of the angular diameter dist…
Correlation of CMB with large-scale structure: II. Weak lensing
Christopher M. Hirata, Shirley Ho, Nikhil Padmanabhan +2
We investigate the correlation of gravitational lensing of the cosmic microwave background (CMB) with several tracers of large-scale structure, including luminous red galaxies (LRG…
Correlation of CMB with large-scale structure: I. ISW Tomography and Cosmological Implications
Shirley Ho, Christopher M. Hirata, Nikhil Padmanabhan +2
We cross-correlate large scale structure (LSS) observations from a number of surveys with CMB anisotropies from WMAP to investigate the Integrated Sachs-Wolfe (ISW) effect as a fun…
Exploring the Variable Sky with the Sloan Digital Sky Survey
Branimir Sesar, Zeljko Ivezic, Robert H. Lupton +29
We quantify the variability of faint unresolved optical sources using a catalog based on multiple SDSS imaging observations. The catalog covers SDSS Stripe 82, and contains 58 mill…
SDSS Standard Star Catalog for Stripe 82: the Dawn of Industrial 1% Optical Photometry
Zeljko Ivezic, J. Allyn Smith, Gajus Miknaitis +2
We describe a standard star catalog constructed using multiple SDSS photometric observations (at least four per band, with a median of ten) in the system. The catalog inclu…
An Improved Photometric Calibration of the Sloan Digital Sky Survey Imaging Data
N. Padmanabhan, D. J. Schlegel, D. P. Finkbeiner +21
We present an algorithm to photometrically calibrate wide field optical imaging surveys, that simultaneously solves for the calibration parameters and relative stellar fluxes using…
