Thumbnails showing the Chandra X-ray brightness distribution in the 0.5 - 7.0 keV band for 28 systems selected from the HIFLUGS sample. The color bar indicates the X-ray surface brightness in units of photon counts s^-1 arcsec^-2 cm^-2. The black and cyan crosses in each panel show the positions of the X-ray brightness peak and the BCG, respectively. The white horizontal bar in each panel corresponds to a spatial scale of 60''.
Systematic Perturbations of the Thermodynamic Properties in Cool Cores of HIFLUGCS Galaxy Clusters
Top: X-ray surface brightness of the galaxy cluster MACS J1311.0-0310 taken by the Chandra X-ray Observatory (left) and its X-ray residual image after removing the mean profile (right). Bottom: X-ray surface brightness of a simulated galaxy cluster produced by our hydrodynamic simulation (left) and its X-ray residual image (right).
Gas Density Perturbations in the Cool Cores of CLASH Galaxy Clusters
Left: X-ray surface brightness of the galaxy cluster Abell 907 taken by the Chandra X-ray Observatory. Right: Residual image of X-ray surface brightness after subtracting its global profile from the original image.
Line-of-Sight Gas Sloshing in the Cool Core of Abell 907
Top Left: X-ray surface brightness of the galaxy cluster RX J1347.5-1145 taken by the Chandra X-ray Observatory. The white contours show the surface mass density map of this galaxy cluster measured by the strong-lensing analysis using Hubble Space Telescope (HST). Top Right: Same as top left but for the image of the Sunyaev-Zel'dovich effect observed by ALMA. Bottom Left: Same as top left but for the X-ray residual image after removing the global profile of this galaxy cluster from top left. Bottom Right: Same as top right, but for the residual image of the Sunyaev-Zel'dovich effect.
A Cool Core Disturbed: Observational Evidence for the Coexistence of Subsonic Sloshing Gas and Stripped Shock-heated Gas around the Core of RX J1347.5-1145
Left: Bulk velocity (v_bulk) map of the intracluster medium in the core of the X-ray brightest galaxy cluster, the Perseus cluster, with respect to the redshift z = 0.017284 (heliocentric correction applied) in units of km/s. Right: Line-of-sight velocity dispersion (σ_v) of the intracluster medium in units of km/s. The Chandra X-ray contours are overlaid.
