The Distribution of Dark and Luminous Matter in the Unique Galaxy Cluster Merger Abell 2146 Abell 2146 (z = 0.232) consists of two galaxy clusters undergoing a major merger. The system was discovered in previous work, where two large shock fronts were detected using the Chandra X-ray Observatory, consistent with ...
Galaxy Cluster Lensing Masses in Modified Lensing Potentials (2015-10-28)We determine the concentration-mass relation of 19 X-ray selected galaxy clusters from the Cluster Lensing and Supernova Survey with Hubble survey in theories of gravity that directly modify the lensing potential. We model ...
Dynamical Analysis of Galaxy Cluster Merger Abell 2146 (Oxford Univ Press, 2015-09-03)We present a dynamical analysis of the merging galaxy cluster system Abell 2146 using spectroscopy obtained with the Gemini Multi-Object Spectrograph on the Gemini North telescope. As revealed by the Chandra X-ray Observatory, ...
Testing Metallicity Indicators at Z ~ 1.4 with the Gravitationally Lensed Galaxy CASSOWARY 20* (Oxford University Press, 2014-03-27)We present X-shooter observations of CASSOWARY 20 (CSWA 20), a star-forming (SFR ~ 6 M⊙ yr⁻¹) galaxy at z = 1.433, magnified by a factor of 11.5 by the gravitational lensing produced by a massive foreground galaxy at z = ...
Shock Fronts, Electron-Ion Equilibration and Intracluster Medium Transport Processes in the Merging Cluster Abell 2146 (2012-02)We present a new 400-ks Chandra X-ray observation of the merging galaxy cluster Abell 2146. This deep observation reveals detailed structure associated with the major merger event including theMach numberM =2.3±0.2 bowshock ...
Refractive Convergent Plasma Lenses Explain Extreme Scattering Events and Pulsar Scintillation (2012-02-27)We propose convergent plasma lenses, possibly from current sheets, as a generic solution to strong interstellar scattering. These lenses resolve the overpressure problem by geometric alignment as noted by Goldreich & ...
