Theoretical ISM Pressure and Electron Density Diagnostics for Local and High-redshift Galaxies

Kewley, Lisa; Nicholls, David; Sutherland, Ralph; Rigby, J. R.; Acharyya, Ayan; Dopita, Michael; Bayliss, Matthew B.

Description

We derive new self-consistent theoretical UV, optical, and IR diagnostics for the interstellar medium (ISM) pressure and electron density in the ionized nebulae of star-forming galaxies. Our UV diagnostics utilize the intercombination, forbidden, and resonance lines of silicon, carbon, aluminum, neon, and nitrogen. We also calibrate the optical and IR forbidden lines of oxygen, argon, nitrogen, and sulfur. We show that line ratios used as ISM pressure diagnostics depend on the gas-phase...[Show more]
