Tracing the [FeII]/[NeII] ratio within star forming dwarf galaxies: a Spitzer IRS archival study
B. O'Halloran, S. C. Madden, N. P. Abel
Archival Spitzer observations of 41 starburst galaxies that span a wide range in metallicity reveal for the first time a correlation between the [FeII]/[NeII] 26.0/12.8 micron rati…

The Interstellar Medium of Young Stellar Clusters from the Mid-Infrared Point of View
Suzanne Madden
Effects of young stellar clusters on their gas and dust environment are probed using mid-infrared (MIR) wavelengths. The strong MIR [NeIII]/[NeII] ratios (5 to 10) reveal the prese…

The dark side of star formation in the Antennae galaxies
I. F. Mirabel, L. Vigroux, V. Charmandaris +6
We compare mid-infrared images of the Antennae galaxies (NGC 4038/39) from the Infrared Space Observatory, with optical images from the Hubble Space Telescope. The mid-infrared obs…
