Journal ArticleDOI
On galaxies and homology
Gregory S. Novak,Gregory S. Novak,Gregory S. Novak,Patrik Jonsson,Patrik Jonsson,Joel R. Primack,Thomas J. Cox,Avishai Dekel +7 more
TL;DR: In this article, the authors argue that the most useful definition is that a set of galaxies is homologous if they are the same in all respects up to three dimensional scaling constants which may differ from one galaxy to the next.
Journal ArticleDOI
The Small Scale Velocity Dispersion of Galaxies: A Comparison of Cosmological Simulations
TL;DR: The velocity dispersion of galaxies on small scales can be estimated from the p 12 (r), anisotropy of the galaxy-galaxy correlation function in redshift space (Davis & Peebles) as discussed by the authors.
Book ChapterDOI
Hot dark matter in cosmology
TL;DR: The most successful structure formation models have been those in which most of the mass in the Universe is in the form of cold dark matter (CDM) as mentioned in this paper, although mixed models with both cold and hot matter (CHDM) were also proposed in 1984 [12.1], although not investigated in detail until the early 1990s.
Journal ArticleDOI
Visualization of Cold + Hot and Cold Dark Matter Cosmologies versus CfA1 Data
TL;DR: In this article, the authors used state-of-the-art visualization techniques to explore cold + hot (CHDM) and cold dark matter (CDM) cosmologies and contrast them to each other (in real and redshift space) and to the CfA1 data (in red-shift space).
Journal ArticleDOI
Dark matter and cosmology: CDM with a cosmological constant (ACDM) vs. CDM with hot dark matter (CHDM)
Joel R. Primack,Anatoly Klypin +1 more
TL;DR: In this article, the authors discuss the two most popular variants of CDM that might agree with the data: ACDM and CHDM, and discuss critical observational tests for both models.
