High-Resolution Optical Rotation Curves of Low-Luminosity Spiral Galaxies
L. D. Matthews, J. S. Gallagher, III
We present optical longslit spectroscopic observations of 21 low-luminosity, extreme late-type spiral galaxies. Our sample is comprised of Sc-Sm Local Supercluster spirals with mod…
Field Strengths of Linearized 5D, N = 1 Superfield Supergravity On a 3-Brane
S. James Gates, William D. Linch, III +1
Recently a description of linearized 5D supergravity in 4D, N =1 superspace was presented. By analyzing the on-shell component Lagrangian, this description was proven to be Lorentz…
A Robust Determination of the Time Delay in 0957+561A,B and a Measurement of the Global Value of Hubble's Constant
Tomislav Kundic, Edwin L. Turner, Wesley N. Colley +9
Photometric monitoring of the gravitational lens system 0957+561A,B in the g and r bands with the Apache Point Observatory (APO) 3.5 m telescope during 1996 shows a sharp g band ev…
Inflation in Kaluza-Klein Theory: Relation between the Fine-Structure Constant and the Cosmological Constant
Li-Xin Li, J. Richard Gott, III
In this paper we investigate a model of an inflationary universe in Kaluza-Klein theory, which is a four-dimensional de Sitter space plus a one-dimensional compactified internal sp…
Dark Energy as Double N-Flation--Observational Predictions
J. Richard Gott, III, Zachary Slepian
We propose a simple model for dark energy useful for comparison with observations. It is based on the idea that dark energy and inflation should be caused by the same physical proc…
Time-Dependence of the Mass Accretion Rate in Cluster Cooling Flows
Eric A. Lufkin, Craig L. Sarazin, Raymond E. White +1
We analyze two time-dependent cluster cooling flow models in spherical symmetry. The first assumes that the intracluster gas resides in a static external potential, and includes th…
