The Galaxy Cluster Concentration-Mass Scaling Relation

Understand

Scaling relations of clusters have made them particularly important cosmological probes of structure formation.

• In this work, we present a comprehensive study of the relation between two profile observables, concentration ($\mathrm{c_{vir}}$) and mass ($\mathrm{M_{vir}}$).
• We have collected the largest known sample of measurements from the literature which make use of one or more of the following reconstruction techniques: Weak gravitational lensing (WL), strong gravitational lensing (SL), Weak+Strong Lensing (WL+SL), the Caustic Method (CM), Line-of-sight Velocity Dispersion (LOSVD), and X-ray.
• We find that the concentration-mass (c-M) relation is highly variable depending upon the reconstruction technique used.
