On the Measurement of Vorticity in Astrophysical Fluids
Steven R. Spangler
Vorticity is central to the nature of, and dynamical processes in turbulence, including turbulence in astrophysical fluids. The results of \cite{Raymond20a,Raymond20b} on vorticity…
Persistent Plasma Waves in Interstellar Space Detected by Voyager 1
S. K. Ocker, J. M. Cordes, S. Chatterjee +3
In 2012, Voyager 1 became the first in situ probe of the very local interstellar medium. The Voyager 1 Plasma Wave System has given point estimates of the plasma density spanning a…
A Method for a Pseudo-Local Measurement of the Galactic Magnetic Field
Steven R. Spangler
Much of the information about the magnetic field in the Milky Way and other galaxies comes from measurements which are path integrals, such as Faraday rotation and the polarization…
Realistic Models for Filling and Abundance Discrepancy Factors in Photoionised Nebulae
Brandon M. Bergerud, Steven R. Spangler, Kara M. Beauchamp
When comparing nebular electron densities derived from collisionally excited lines (CELs) to those estimated using the emission measure, significant discrepancies are common. The s…
Analytic Estimates of the Effect of Plasma Density Fluctuations on HII Region Density Diagnostics
Steven R. Spangler, Brandon M. Bergerud, Kara M. Beauchamp
An analytic calculation is made of the effect of plasma density fluctuations on some spectroscopic diagnostics commonly used in the study of HII regions and planetary nebulae. To p…
Radio Observational Constraints on Turbulent Astrophysical Plasmas
Tim Bastian, James Cordes, Justin Kasper +6
Remarkable progress has been made in understanding turbulent astrophysical plasmas in past decades including, notably, the solar wind and the interstellar medium. In the case of th…
