Cluster Cores, Gravitational Lensing, and Cosmology
Ricardo A. Flores, Joel R. Primack
Many multiply--imaged quasars have been found over the years, but none so far with image separation in excess of $8\arcsec$. The absence of such large splittings has been used as a…
Small-Scale Power Spectrum and Correlations in LCDM
Anatoly Klypin, Joel Primack, Jon Holtzman
Cosmological models with a positive cosmological constant and have a number of attractive features. A larger Hubble constant, which can be compatible with the recent HST es…
Improved Ways to Compare Simulations to Data
Joel R. Primack
Theoretical models for structure formation with Gaussian initial fluctuations have been worked out in considerable detail and compared with observations on various scales. It is on…
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…
Probing the Era of Galaxy Formation via TeV Gamma Ray Absorption by the Near Infrared Extragalactic Background
D. MacMinn, J. R. Primack
We present models of the extragalactic background light (EBL) based on several scenarios of galaxy formation and evolution. We have treated galaxy formation with the Press-Schecter…
Status of Cosmological Parameters: Can ?
Joel R. Primack
I discuss the Hubble parameter , the age of the universe , the density , and the cosmological constant . To focus the discussion, I concentrate on the issue of th…
