A Quantitative Analysis of IRAS Maps of Molecular Clouds
Jennifer J. Wiseman, Fred C. Adams
We present an analysis of IRAS maps of five molecular clouds: Orion, Ophiuchus, Perseus, Taurus, and Lupus. For the classification and description of these astrophysical maps, we u…
Formal Results Regarding Metric-Space Techniques for the Study of Astrophysical Maps
Fred C. Adams, Jennifer J. Wiseman
We extend a newly developed formal system for the description of astrophysical maps. In this formalism, we consider the difference between maps to be the distance between elements…
The Settling of Warped Disks in Oblate Dark Halos
John Dubinski, Konrad Kuijken
When a galaxy forms, the disk may initially be tilted with respect to a flattened dark halo. The misalignment between the disk and the halo is a common explanation for galactic dis…
X-Ray and Optical Properties of Groups of Galaxies
I. P. Dell'Antonio, M. J. Geller, D. G. Fabricant
We examine the relationship between the group x-ray luminosity in the 0.3-3.5 keV band and the measured velocity dispersion, and galaxy surface number density. We find definite cor…
Merging Neutron Stars I: Initial Results for Coalescence of Non-Corotating Systems
M. B. Davies, W. Benz, T. Piran +1
We present 3D Newtonian simulations of the coalescence of two neutron stars, using a Smoothed Particle Hydrodynamics (SPH) code. We begin the simulations with the two stars in a ha…
