On Galaxy-Cluster Sizes and Temperatures
We show that the distribution of the sizes and temperatures of clusters can be used to constrain cosmological models. The size-temperature (ST) distribution predicted in a flat Gaussian cluster-abundance-normalized Ω0 = 0.3 model agrees well with the fairly tight ST relation observed. A larger power-spectrum amplitude σ8 would give rise to a larger scatter about the ST relation as would a large...
متن کاملApparent and actual galaxy cluster temperatures
The redshift evolution of the galaxy cluster temperature function is a powerful probe of cosmology. However, its determination requires the measurement of redshifts for all clusters in a catalogue, which is likely to prove challenging for large catalogues expected from XMM-Newton, which may contain of the order of 2000 clusters with measurable temperatures, distributed around the sky. In this p...
متن کاملSource Temperatures and Sizes in Central Collisions
For midrapidity fragments from central 50-200 AMeV Au+Au collisions temperatures from double ratios of isotopic yields were compared with temperatures from particle un-bound states. Temperatures from particle unbound states with T ' 4 ? 5MeV show with increasing beam energy an increasing diierence to temperatures from double ratios of isotopic yields, which increase from T ' 5MeV to T ' 12MeV. ...
متن کاملGravitationaìconvergence' and Galaxy Cluster Masses
Two colour photometry of the cluster A1689 reveals a `relative magniication-bias' between lensed blue and red background galaxies, arising from a dependence of the faint galaxy count-slope on colour. The colour distribution is skewed blueward of the far eld, allowing us to measure the cluster magniication and to understand the notorious blueness of large arcs. We show that the magniication info...
متن کاملImprint of galaxy formation and evolution on globular cluster properties
We discuss the origin of physical properties of globular cluster systems (GCSs) in galaxies in terms of galaxy formation and evolution processes. Based on numerical simulations of dynamical evolution of GCSs in galaxies, we particularly discuss (1) the origin of radial density profiles of GCSs, (2) kinematics of GCSs in elliptical galaxies, (3) transformation from nucleated dwarf galaxies into ...
