Cosmological Constraints from Sunyaev-Zel'dovich-Selected Clusters with X-ray Observations in the First 178 Square Degrees of the South Pole Telescope Survey
B. A. Benson, T. de Haan, J. P. Dudley +73
We use measurements from the South Pole Telescope (SPT) Sunyaev Zel'dovich (SZ) cluster survey in combination with X-ray measurements to constrain cosmological parameters. We prese…
AGES: The AGN and Galaxy Evolution Survey
C. S. Kochanek, D. J. Eisenstein, R. J. Cool +12
The AGN and Galaxy Evolution Survey (AGES) is a redshift survey covering, in its standard fields, 7.7 square degrees of the Bootes field of the NOAO Deep Wide-Field Survey (NDWFS).…
The Universal Gas Mass Fraction in Clusters of Galaxies
Laurence P. David, Christine Jones, William Forman
We obtained a deep 150ksec Chandra observation of the optically selected cluster of galaxies, RCS 2318+0034, to investigate the gas mass fraction in this system. Combining our deep…
Deep Chandra Observations of Edges and Bubbles in the NGC 5846 Galaxy Group
M. E. Machacek, D. Jerius, R. P. Kraft +5
We use a combined 120 ks Chandra exposure to analyze X-ray edges produced by non-hydrostatic gas motions (sloshing) from galaxy collisions, and cavities formed by AGN activity. Evi…
Self-similar scaling and evolution in the galaxy cluster X-ray Luminosity-Temperature relation
B. J. Maughan, P. A. Giles, S. W. Randall +2
We investigate the form and evolution of the X-ray luminosity-temperature (LT) relation of a sample of 114 galaxy clusters observed with Chandra at 0.1<z<1.3. The clusters were div…
Sloshing Gas in the Core of the Most Luminous Galaxy Cluster RXJ1347.5-1145
Ryan E. Johnson, John A. ZuHone, Christine Jones +2
We present new constraints on the merger history of the most X-ray luminous cluster of galaxies, RXJ1347.5-1145, based its unique multiwavelength morphology. Our X-ray analysis con…
