2. APOD: 2007 May 16 - Dark Matter Ring Modeled around Galaxy Cluster CL0024 17
... Dark Matter Ring Modeled around Galaxy Cluster CL0024+17 . ... It is the relatively weak distortions of the many distant faint blue galaxies all over the image, however, that indicates the existence of the dark matter ring. ... A hypothesis for the formation of the huge dark matter ring holds that it is a transient feature formed when galaxy cluster CL0024+17 collided with another cluster of galaxies about one billion years ago, leaving a ring similar to when a rock is thrown in a pond. ...

7. Errors in the Steady State and Quasi-SS Models
The Steady State model of the Universe was proposed in 1948 by Bondi and Gold and by Hoyle. ... At the time the Steady State model was proposed, the Big Bang model was in trouble because the value of the Hubble constant was clearly bigger than the inverse of the age of the Universe. ... Thus the Steady State model has flat spatial sections like the critical density Big Bang model. ... The Steady State model has no adjustable parameters to correct for this error, but the Big Bang does. ...

13. Seminars
... Dark matter in normal galaxies . ... I will pay attention to such issues as the constraints on dark matter profile, micro-lensing counts from the galactic bar, rotation and the structure of the bar. One of the central issues of the modeling is the exchange of the angular momentum between the disk and the dark matter. ... Our results indicate that in realistic models the exchange of angular momentum between the bar and the dark matter is much smaller than previously estimated. ...

17. http://star.arm.ac.uk/~gar/research/compact.binaries.html
... Compact Binaries . ... Unlike the Sun, most stars in our Galaxy orbit another star: these systems are called binary stars. Generally it takes many years for the two stars to orbit around each other. ... These binaries are interesting for many reasons. One is that they are predicted to emit lots of gravitational waves. ... Over time as gravitational waves are emitted, the time taken for the two stars to orbit one another changes by a small but measurable amount. ...

Evolution of Galaxy Clustering Ray Carlberg University of Toronto, Canada Galaxy clustering is a fundamental statistic whose redshift depen- dence tests the cosmological world model, the density uctuation spectrum and the statistical theory of galaxy formation. Below redshift one the Canadian Network for Observational Cosmology eld galaxy survey nds a slow decline of clustering with increas- ing redshift, most consistent with biasing models in a low density at CDM universe. ...
