The rapid evolution of AGN feedback in brightest cluster galaxies: switching from quasar-mode to radio-mode feedback
J. Hlavacek-Larrondo, A. C. Fabian, A. C. Edge +4
We present an analysis of the 2-10 keV X-ray emission associated with the active galactic nuclei (AGNs) in brightest cluster galaxies (BCGs). Our sample consists of 32 BCGs that li…
Gravitationally Lensed Galaxies at 2<z<3.5: Direct Abundance Measurements of Lya Emitters
Lise Christensen, Peter Laursen, Johan Richard +6
Strong gravitational lensing magnifies the flux from distant galaxies, allowing us to detect emission lines that would otherwise fall below the detection threshold for medium-resol…
The Low Mass End of the Fundamental Relation for Gravitationally Lensed Star Forming Galaxies at 1<z<6
Lise Christensen, Johan Richard, Jens Hjorth +6
We present VLT/X-shooter spectra of 13 galaxies in the redshift range 1< z < 6, which are strongly lensed by massive galaxy clusters. Spectroscopic redshifts are measured for nine…
The three-dimensional geometry and merger history of the massive galaxy cluster MACS J0358.8-2955
Li-Yen Hsu, Harald Ebeling, Johan Richard
We present results of a combined X-ray/optical analysis of the dynamics of the massive cluster MACS J0358.8-2955 (z=0.428) based on observations with the Chandra X-ray Observatory,…
A Weak-Lensing Mass Reconstruction of the Large-Scale Filament Feeding the Massive Galaxy Cluster MACSJ0717.5+3745
Mathilde Jauzac, Eric Jullo, Jean-Paul Kneib +6
We report the first weak-lensing detection of a large-scale filament funneling matter onto the core of the massive galaxy cluster MACSJ0717.5+3745. Our analysis is based on a mosai…
Weighing the Giants - III. Methods and Measurements of Accurate Galaxy Cluster Weak-Lensing Masses
Douglas E. Applegate, Anja von der Linden, Patrick L. Kelly +7
We report weak-lensing masses for 51 of the most X-ray luminous galaxy clusters known. This cluster sample, introduced earlier in this series of papers, spans redshifts 0.15 < z_cl…
