About the CEREAL Sample

Data

The complete set of observations comprising the CEREAL sample is available in Chandra Data Collection 482. New data were collected as part of Chandra program 23800272 and Chandra program 25800481.

Publications

The CEREAL sample is described further in "The Cluster Evolutionary Reference Ensemble at Low-z (CEREAL) Sample of Galaxy Clusters. I. X-Ray Morphological Properties and Demographics" (Paper I) and "The Cluster Evolutionary Reference Ensemble at Low-$z$ (CEREAL) Sample of Galaxy Clusters II: Thermodynamic Profiles and Cool Core Properties" (Paper II; submitted to ApJ).

Selection

The figure below shows the selection criteria for the high-mass and low-mass CEREAL subsamples. The grey stars represent all known clusters from the second Planck catalog. The high-mass clusters have masses in the range \(4.5 \times 10^{14}\ M_\odot < M_{500} < 10 \times 10^{14}\ M_\odot\) and redshifts \(0.15 < z < 0.25\). The low-mass clusters have masses \(2.0 \times 10^{14}\ M_\odot < M_{500} < 4.5 \times 10^{14}\ M_\odot\) and redshifts \(0.085 < z < 0.125\). We remove clusters falling within \(20°\) of the Galactic plane as well as a handful of low S/N clusters as described in Papers I and II, leaving us with 108 high-mass and 60 low-mass clusters.
