Galactic hydrostatic equilibrium with magnetic tension and cosmic-ray diffusion
- A. Boulares, D. Cox
- Physics
- 1 December 1990
Three gravitational potentials differing in the content of dark matter in the Galactic plane are used to study the structure of the z-distribution of mass and pressure in the solar neighborhood. A…
THE THREE-PHASE INTERSTELLAR MEDIUM REVISITED
- D. Cox
- Physics
- 15 August 2005
▪ Abstract The interstellar medium in the vicinity of the Sun is arranged in large-scale structures of bubble walls, sheets, and filaments of warm gas, within which close to the midplane there are…
Cooling and evolution of a supernova remnant.
- D. Cox
- Physics
- 15 November 1972
Discussion of the structure, evolution, and cooling of an old supernova remnant, aimed at providing a theoretical framework for relating remnants with similar energies and environments but of…
The local interstellar medium
- D. Cox, R. J. Reynolds
- Physics
- 1987
Observations and theoretical models of the local interstellar medium (LISM), defined as the region within a column density contour of 10 to the 19th H atoms/sq cm, are reviewed. The existence and…
Modeling W44 as a Supernova Remnant in a Density Gradient with a Partially Formed Dense Shell and Thermal Conduction in the Hot Interior. I. The Analytical Model
- D. Cox, R. Shelton, M. Rozyczka
- Physics
- 5 June 1998
We show that many observations of W44, a supernova remnant in the Galactic plane at a distance of about 2500 pc, are remarkably consistent with the simplest realistic model. The model remnant is…
Large-scale effects of supernova remnants on the Galaxy - Generation and maintenance of a hot network of tunnels
- D. Cox, Barham W. Smith
- Physics
- 1 May 1974
It is found that a supernova rate on the order of 1 per 50 years in the gaseous disk of our Galaxy is sufficient to generate and maintain throughout the interstellar medium a mesh of interconnected…
A model for the distribution of material generating the soft X-ray background
- S. Snowden, D. Cox, D. McCammon, W. Sanders
- Physics
- 1 May 1990
The observational evidence relating to the soft X-ray diffuse background is discussed, and a simple model for its source and spatial structure is presented. In this simple model with one free…
Spatial and spectral interpretation of a bright filament in the Cygnus Loop
- J. Raymond, J. J. Hester, D. Cox, W. Blair, R. Fesen, T. Gull
- Physics
- 15 January 1988
A comparison is made of optical and UV line intensities and spatial and spectral optical line profiles of a well-defined Cygnus Loop filament with theoretical models. It is found that the sharp…
Ionization equilibrium and radiative cooling of a low-density plasma.
Ionization equilibrium and radiative cooling of high temperature low density plasma, noting cosmic gas cooling curve of line emission from oxygen ion transitions
Completing the evolution of supernova remnants and their bubbles
The filling fraction of hot gas in the ISM is reexamined with new calculations of the very long term evolution of SNRs and their fossil hot bubbles. Results are presented of a 1D numerical solution…
