A Large X-ray Sample of Fossil Groups
Eric D. Miller, Eli Rykoff, Renato de Alencar Dupke +3
We present Chandra snapshot observations of the first large X-ray sample of optically identified fossil groups. For 9 of 14 candidate groups, we are able to determine the X-ray lum…
Precision Measurements of the Cluster Red Sequence using an Error Corrected Gaussian Mixture Model
Jiangang Hao, Benjamin P. Koester, Timothy A. Mckay +10
The red sequence is an important feature of galaxy clusters and plays a crucial role in optical cluster detection. Measurement of the slope and scatter of the red sequence are affe…
Galaxy Clusters in Formation: Determining the Age of the Red-Sequence in Optical and X-ray Clusters at z~1 with HST
Benjamin P. Koester, Michael D. Gladders, David G. Gilbank +7
Using deep two-band imaging from the Hubble Space Telescope, we measure the color-magnitude relations (CMR) of E/S0 galaxies in a set of 9 optically-selected clusters principally f…
Cosmological Constraints from the SDSS maxBCG Cluster Catalog
Eduardo Rozo, Risa H. Wechsler, Eli S. Rykoff +11
We use the abundance and weak lensing mass measurements of the SDSS maxBCG cluster catalog to simultaneously constrain cosmology and the richness--mass relation of the clusters. As…
Subaru Weak Lensing Measurements of Four Strong Lensing Clusters: Are Lensing Clusters Over-Concentrated?
Masamune Oguri, Joseph F. Hennawi, Michael D. Gladders +6
We derive radial mass profiles of four strong lensing selected clusters which show prominent giant arcs (Abell 1703, SDSS J1446+3032, SDSS J1531+3414, and SDSS J2111-0115), by comb…
