Atomic Modeling of Photoionization Fronts in Nitrogen Gas
William J. Gray, P. A. Keiter, H. Lefevre +5
Photoionization fronts play a dominant role in many astrophysical environments, but remain difficult to achieve in a laboratory experiment. Recent papers have suggested that experi…
The Effect of Turbulence on Nebular Emission Line Ratios
William J. Gray, Evan Scannapieco
Motivated by the observed differences in the nebular emission of nearby and high-redshift galaxies, we carry out a set of direct numerical simulations of turbulent astrophysical me…
Effect of Angular Momentum Alignment and Strong Magnetic Fields on the Formation of Protostellar Disks
William J. Gray, Christopher F. McKee, Richard I. Klein
Star forming molecular clouds are observed to be both highly magnetized and turbulent. Consequently the formation of protostellar disks is largely dependent on the complex interact…
Atomic Chemistry In Turbulent Astrophysical Media I: Effect of Atomic Cooling
William J Gray, Evan Scannapieco, Daniel Kasen
We carry out direct numerical simulations of turbulent astrophysical media that explicitly track ionizations, recombinations, and species-by-species radiative cooling. The simulati…
