An X-ray Galaxy Cluster Survey for Investigations of Dark Energy
Z. Haiman, S. Allen, N. Bahcall +34
The amount and nature of dark energy (DE) can be tightly constrained by measuring the spatial correlation features and evolution of a sample of ~ 100,000 galaxy clusters over the r…
Cosmological parameters from SDSS and WMAP
M. Tegmark, M. Strauss, M. Blanton +34
We measure cosmological parameters using the three-dimensional power spectrum P(k) from over 200,000 galaxies in the Sloan Digital Sky Survey (SDSS) in combination with WMAP and ot…
Detection of the Baryon Acoustic Peak in the Large-Scale Correlation Function of SDSS Luminous Red Galaxies
D. J. Eisenstein, I. Zehavi, D. W. Hogg +45
We present the large-scale correlation function measured from a spectroscopic sample of 46,748 luminous red galaxies from the Sloan Digital Sky Survey. The survey region covers 0.7…
The Cosmic Triangle: Revealing the State of the Universe
N. Bahcall, J. P. Ostriker, S. Perlmutter +1
The "cosmic triangle" is introduced as a way of representing the past, present, and future status of the universe. Our current location within the cosmic triangle is determined by…
The Galaxy-mass Correlation Function Measured from Weak Lensing in the SDSS
E. S. Sheldon, D. E. Johnston, J. A. Frieman +8
We present galaxy-galaxy lensing measurements over scales 0.025 to 10 Mpc/h in the Sloan Digital Sky Survey. Using a flux-limited sample of 127,001 lens galaxies with spectroscopic…
The Atacama Cosmology Telescope: DR6 Sunyaev-Zel'dovich Selected Galaxy Clusters Catalog
HSC Collaboration, M. Aguena, S. Aiola +98
We present the results of a search for galaxy clusters in the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) microwave sky maps covering 16293 square degrees in three frequ…
A MaxBCG Catalog of 13,823 Galaxy Clusters from the Sloan Digital Sky Survey
B. P. Koester, T. A. McKay, J. Annis +23
We present a catalog of galaxy clusters selected using the maxBCG redsequence method from Sloan Digital Sky Survey photometric data. This catalog includes 13,823 clusters with velo…
SDSS galaxy bias from halo mass-bias relation and its cosmological implications
U. Seljak, A. Makarov, R. Mandelbaum +7
We combine the measurements of luminosity dependence of bias with the luminosity dependent weak lensing analysis of dark matter around galaxies to derive the galaxy bias and constr…
Detection of intrinsic cluster alignments to 100 Mpc/h in the SDSS
A. Smargon, R. Mandelbaum, N. Bahcall +1
We measure the large-scale intrinsic alignments of galaxy clusters in the Sloan Digital Sky Survey (SDSS) using subsets of two cluster catalogues: 6625 clusters with 0.1<z<0.3 from…
Cosmological parameter analysis including SDSS Ly-alpha forest and galaxy bias: constraints on the primordial spectrum of fluctuations, neutrino mass, and dark energy
U. Seljak, A. Makarov, P. McDonald +18
We combine the constraints from the recent Ly-alpha forest and bias analysis of the SDSS with previous constraints from SDSS galaxy clustering, the latest supernovae, and WMAP . Co…
