New Constraints on Spatial Variations of the Fine Structure Constant from Clusters of Galaxies
I. de Martino, C. J. A. P. Martins, H. Ebeling +1
We have constrained the spatial variation of the fine structure constant using multi-frequency measurements of the thermal Sunyaev-Zeldovich effect of 618 X-ray selected clusters.…
Velocity Segregation and Systematic Biases In Velocity Dispersion Estimates With the SPT-GMOS Spectroscopic Survey
Matthew. B. Bayliss, Kyle Zengo, Jonathan Ruel +15
The velocity distribution of galaxies in clusters is not universal; rather, galaxies are segregated according to their spectral type and relative luminosity. We examine the velocit…
Cluster Mass Calibration at High Redshift: HST Weak Lensing Analysis of 13 Distant Galaxy Clusters from the South Pole Telescope Sunyaev-Zel'dovich Survey
T. Schrabback, D. Applegate, J. P. Dietrich +26
We present an HST/ACS weak gravitational lensing analysis of 13 massive high-redshift (z_median=0.88) galaxy clusters discovered in the South Pole Telescope (SPT) Sunyaev-Zel'dovic…
SPT-GMOS: A Gemini/GMOS-South Spectroscopic Survey of Galaxy Clusters in the SPT-SZ Survey
M. B. Bayliss, J. Ruel, C. W. Stubbs +75
We present the results of SPT-GMOS, a spectroscopic survey with the Gemini Multi-Object Spectrograph (GMOS) on Gemini South. The targets of SPT-GMOS are galaxy clusters identified…
Constraining spatial variations of the fine structure constant using clusters of galaxies and Planck data
I. de Martino, C. J. A. P. Martins, H. Ebeling +1
We propose an improved methodology to constrain spatial variations of the fine structure constant using clusters of galaxies. We use the {\it Planck} 2013 data to measure the therm…
