| Comparison of Cluster Lensing Profiles with Lambda CDM Predictions (2008) | |||||||||
Abstract | |||||||||
| We derive lens distortion and magnification profiles of four well known clusters observed with Subaru. Each cluster is very well fitted by the general form predicted for Cold Dark Matter (CDM) dominated halos, with good consistency found between the independent distortion and magnification measurements. The inferred level of mass concentration is surprisingly high, 8. Comment: Accepted version in ApJL, minor changes | |||||||||
