The C4 Clustering Algorithm: Clusters of Galaxies in the Sloan Digital Sky Survey
Christopher J. Miller, Robert Nichol, Dan Reichart +15
We present the "C4 Cluster Catalog", a new sample of 748 clusters of galaxies identified in the spectroscopic sample of the Second Data Release (DR2) of the Sloan Digital Sky Surve…
The Small-scale Clustering of Luminous Red Galaxies via Cross-Correlation Techniques
Daniel J. Eisenstein, Michael Blanton, Idit Zehavi +5
We present the small-scale (0.2h^{-1} to 7h^{-1} Mpc) cross-correlations between 32,000 luminous early-type galaxies and a reference sample of 16 million normal galaxies from the S…
Where are the missing baryons in clusters?
Bilhuda Rasheed, Neta Bahcall, Paul Bode
Observations of clusters of galaxies suggest that they contain significantly fewer baryons (gas plus stars) than the cosmic baryon fraction. This `missing baryon' puzzle is especia…
Planck Sunyaev-Zel'dovich Cluster Mass Calibration using Hyper Suprime-Cam Weak Lensing
Elinor Medezinski, Nicholas Battaglia, Keiichi Umetsu +9
Using 140 deg Subaru Hyper Suprime-Cam (HSC) survey data, we stack the weak lensing (WL) signal around five Planck clusters found within the footprint. This yields a 15$Ï…
First Identification of a CMB Lensing Signal Produced by Million Galaxies at 4: Constraints on Matter Density Fluctuations at High Redshift
Hironao Miyatake, Yuichi Harikane, Masami Ouchi +6
We report the first detection of the dark matter distribution around Lyman break galaxies (LBGs) at high redshift through the Cosmic Microwave Background (CMB) lensing measurements…
Galaxy Mass and Luminosity Scaling Laws Determined by Weak Gravitational Lensing
Timothy A. McKay, Erin Scott Sheldon, Judith Racusin +18
We present new measurements of scaling laws relating the luminosity of galaxies to the amplitude and shape of their dark matter halos. Early imaging and spectroscopic data from the…
