The two rings of (50000) Quaoar
C. L. Pereira, B. Sicardy, B. E. Morgado +66
Quaoar is a classical Trans-Neptunian Object (TNO) with an area equivalent diameter of 1,100 km and an orbital semi-major axis of 43.3 astronomical units. Based on stellar occultat…
Global Relationships Among the Physical Properties of Stellar Systems
David Burstein, Ralf Bender, Sandra Faber +1
The kappa-space three-dimensional parameter system was originally defined for the physical properties of dynamically hot galaxies. Here we define self-consistent kappa-parameters f…
Filament and Shape Statistics: A Quantitative Comparison of Cold + Hot and Cold Dark Matter Cosmologies vs. CfA1 Data
Romeel Davé, Doug Hellinger, Joel Primack +2
A new class of geometric statistics for analyzing galaxy catalogs is presented. Filament statistics quantify filamentarity and planarity in large scale structure in a manner consis…
The Small Scale Velocity Dispersion of Galaxies: A Comparison of Cosmological Simulations
Rachel S. Somerville, Joel R. Primack, Richard Nolthenius
The velocity dispersion of galaxies on small scales ( Mpc), , can be estimated from the anisotropy of the galaxy-galaxy correlation function in redshift sp…
Filament Statistics: A Quantitative Comparison of Cold + Hot and Cold Dark Matter Cosmologies with CfA1 Data
Romeel Davé, Doug Hellinger, Richard Nolthenius +2
A new class of geometric statistics for analyzing galaxy catalogs is presented. {\it Filament statistics} quantify filamentarity and planarity in large scale structure in a manner…
Galaxy Groups in Cold + Hot and CDM Universes: Comparison with CfA
Richard Nolthenius, Anatoly Klypin, Joel R. Primack
This letter presents results of new high resolution Cold + Hot Dark Matter (CHDM) and Cold Dark Matter (CDM) simulations. Properties of groups in these simulations reflect th…
