The Subaru weak lensing mass map (white contour) is overlaid on top of the AMiBA SZE measurement (color map) for the cluster Abell 2142. The open and filled black circles represent the field of view and resolution of AMiBA respectively. The filled white circle represents the resolution of the weak lensing data. This map shows that hot gas as seen in both SZE and the dark matter, traces an elongated distribution in the NW-SE direction (Ho et al., 2009, ApJ, 694, 1610).
