    The Ionized Gas in Nearby Galaxies as Traced by the [N II] 122 and 205 μm Transitions
    The [N ii] 122 and 205 μm transitions are powerful tracers of the ionized gas in the interstellar medium. By combining data from 21 galaxies selected from the...

    The Iron Abundance in Galactic Planetary Nebulae
    We constrain the iron abundance in a sample of 33 low-ionization Galactic planetary nebulae (PNe) using [Fe III] lines and correcting for the contribution of...
