The Consistency of Cosmic Flows on 100 Mpc/h Scales
Michael J Hudson
We have compared the bulk flow of recent large-scale peculiar velocity surveys (SMAC, SC, Lauer and Postman, Willick, EFAR and Tonry's SNIa sample) to each other, allowing for the…
Cosmology with the Space-Luminosity Distribution of Virialized Halos
Christian Marinoni, Michael J. Hudson, Giuliano Giuricin
We derive the observed luminosity function of virialized systems. Coupling this statistic with the mass function predicted by CDM cosmogonies we obtain the functional behavior of t…
Cluster Distances: the Good, the Bad and the Ugly
John R. Lucey, Russell J. Smith, Michael J. Hudson +2
Galaxy clusters are important targets for peculiar velocity studies as a direct comparison of the various distance indicators can be made. The potential problem of an environmental…
Are Recent Peculiar Velocity Surveys Consistent?
Michael J. Hudson, Russell J. Smith, John R. Lucey +2
We compare the bulk flow of the SMAC sample to the predictions of popular cosmological models and to other recent large-scale peculiar velocity surveys. Both analyses account for a…
Bulk-flow and beta_I from the SMAC project
Russell J. Smith, Michael J. Hudson, John R. Lucey +2
The SMAC project is a Fundamental Plane peculiar velocity survey of 56 clusters of galaxies to a depth of cz ~ 12000 km/s. We present here some results from the analysis of the SMA…
Conference Highlights: Cosmic Flows
Michael J. Hudson
I summarize the highlights of "Cosmic Flows: Towards an Understanding of the Large-scale Structure in the Universe", a workshop held in Victoria, Canada in July 1999.
