Merged ionization/dissociation fronts in planetary nebulae
William J. Henney, R. J. R. Williams, Gary J. Ferland +2
The hydrogen ionization and dissociation front around an ultraviolet radiation source should merge when the ratio of ionizing photon flux to gas density is sufficiently low and the…
On the enhanced cosmic-ray ionization rate in the diffuse cloud towards Zeta Persei
Gargi Shaw, G. J. Ferland, R. Srianand +3
The spatial distribution of the cosmic-ray flux is important in understanding the Interstellar Medium (ISM) of the Galaxy. This distribution can be analyzed by studying different m…
Dielectronic recombination and stability of warm gas in AGN
Susmita Chakravorty, Ajit K. Kembhavi, Martin Elvis +2
Understanding the thermal equilibrium (stability) curve may offer insights into the nature of the warm absorbers often found in active galactic nuclei. Its shape is determined by f…
