The X-ray Fundamental Plane of Clusters of Galaxies Yutaka Fujita National Astronomical Observatory, Japan We analyze the relations among central gas density, core radius, and temperature of X-ray clusters by plotting the observational data in the three-dimensional (log  gas;0 , log r c , and log T gas ) space and nd that the data lie on a 'fundamental plane'. ... The two parameters describing the plane are formation redshift and temperature of clusters. ...

... The overall globular cluster population is divided by gap in the metallicity function at [Fe/H]=-1.0 into two discrete groups with well-defined maxima at [Fe/H]=-1.60?0.03 dex, and -0.60?0.04 dex. ... Clusters with extremely blue horizontal branches occupy a spherical volume of radius ~ 9 kpc, have high rotational velocities ( V rot =77?33 km/s), have substantial and equal negative radial and vertical metallicity gradients, and are, on average, the oldest group (the old-halo subsystem). ...
