Scientific paper

We will conduct mid-IR imaging with IRAC at 4.5 and 8.0 microns to survey the stellar population for embedded stars what would not be identifiable in optical surveys. Mid-IR spectroscopy with IRS in low resolution covering the wavelength range from 5 to 40 microns will be used to obtain spatially resolved spectra of the mid-IR nebular emission lines and the PAH lines in a small sample of well-studied, nearby dwarf starburst galaxies. Mid-IR spectroscopy with IRS in high resolution covering the low wavelength range from 10 to 19.5 microns to search for the molecular hydrogen emission at 0-0 S(1) 17 microns and 0-0 S(2) 12.3 microns in low metallicity environments.
