An Improved Cluster Richness Estimator
Eduardo Rozo, Eli S. Rykoff, Benjamin P. Koester +11
Minimizing the scatter between cluster mass and accessible observables is an important goal for cluster cosmology. In this work, we introduce a new matched filter richness estimato…
Constraining the Scatter in the Mass-Richness Relation of maxBCG Clusters With Weak Lensing and X-ray Data
Eduardo Rozo, Eli S. Rykoff, August Evrard +10
We measure the logarithmic scatter in mass at fixed richness for clusters in the maxBCG cluster catalog, an optically selected cluster sample drawn from SDSS imaging data. Our meas…
GRB 071003: Broadband Follow-up Observations of a Very Bright Gamma-Ray Burst in a Galactic Halo
D. A. Perley, W. Li, R. Chornock +26
The optical afterglow of long-duration GRB 071003 is among the brightest yet to be detected from any GRB, with R ~ 12 mag in KAIT observations starting 42 s after the GRB trigger,…
The L_X--M relation of Clusters of Galaxies
E. S. Rykoff, A. E. Evrard, T. A. McKay +8
We present a new measurement of the scaling relation between X-ray luminosity and total mass for 17,000 galaxy clusters in the maxBCG cluster sample. Stacking sub-samples within fi…
