Abstract: We compare the evolution of morphology in X-ray cluster data and in clusters obtained in a simulation of flat CDM, normalized to the observed cluster abundance. We find that the evolution rate in model clusters is significantly higher than in data clusters. Astrophysics (astro-ph) Cite as: arXiv:astro-ph/ (or arXiv:astro-ph Author: R. Valdarnini, S.

The conference presents papers on recommended ground- and space-based initiatives for the s. The need to restore the research infrastructure at the university level is addressed as well as ways of achieving a balanced space program. Consideration is also given to science opportunities, astronomy and the computer revolution, lunar astronomy, policy opportunities, and astronomy as a national. Research in Astronomy and Astrophysics is an international journal publishing original research papers and reviews across all Based on analysis of the data selected for the current investigation, we further found that out of craters, (%) craters exist near the equator, (%) are in the northern hemisphere and (%. Data analysis methods applied to physical interpretation were mainly considered (cluster photometry, astronomical optical data compression, cluster analysis for pulsar light curves, coded aperture imaging). New parallel and vectorial machines were presented (cellular machines, PAPIA-machine, MPP-machine, vector computers in astronomy). The Astronomy and Astrophysics Review publishes invited reviews by leading experts from around the world. The range of topics covered includes all areas of astronomy and astrophysics; cosmic ray physics; studies in the solar system; astrobiology; developments in laboratory or particle physics directly relevant to astronomy; instrumentation; computational or statistical methods with .
