SUMMARY:Multi-wavelength Studies of Galaxy Clusters and Their Use as Cosmo
 logical Probes - Doron Lemze (Tel Aviv)

CONTACT:Dr Jonathan Gair
DESCRIPTION:The availability of extensive optical measurements of member g
 alaxies\, strong and weak gravitational lensing measurements\, and resolve
 d X-ray images\, afford detailed determination of the galaxy\, gas\, and d
 ark matter spatial profiles. I will describe the results from combined ana
 lyses of high quality multi-wavelength data by implementing a new\, largel
 y model-independent approach. I will then show that the contribution of cl
 usters to the the X-ray background can be used to set meaningful constrain
 ts on alternative non-Gaussian cosmological models.
