Dynamics of a Dark Matter Field with a Quartic Self-Interaction Potential
P. J. E. Peebles
It may prove useful in cosmology to understand the behavior of the energy distribution in a scalar field that interacts only with gravity and with itself by a pure quartic potentia…
Summary: Comments on the State of our Subject
P. J. E. Peebles
This conference shows the impressive rate of advances in the observations and theoretical interpretations of large-scale structure. But to explain my feeling that we may still have…
A Model for Structure Formation Seeded by Gravitationally Produced Matter
Wayne Hu, P. J. E. Peebles
This model assumes the baryons, radiation, three families of massless neutrinos, and cold dark matter were mutually thermalized before the baryon number was fixed, primeval curvatu…
A Galaxy X-ray Fundamental Plane?
M. Fukugita, P. J. E. Peebles
We suggest the radii and luminosities of the X-ray emitting halos of elliptical galaxies define a fundamental plane with the star velocity dispersions, as for the corresponding opt…
Summary; Inflation and Traditions of Research
P. J. E. Peebles
One way to judge the impact of the inflation concept is to consider where cosmology might be today without it. The Einstein-de Sitter model would not have been so keenly defended,…
Noninteracting dark matter
P. J. E. Peebles, A. Vilenkin
Since an acceptable dark matter candidate may interact only weakly with ordinary matter and radiation, it is of interest to consider the limiting case where the dark matter interac…
