Scientific paper

We propose to use the short-low and short-high modules of the IRS to map the extremely low-metallcity blue compact dwarf galaxy, IZw18. Having just 1/30th the solar metallicity, IZw18 has been studied extensively at nearly all wavelengths and has been considered a local analogue to the formation of primordial galaxies in the early universe. We aim at obtaining deep mid-IR spectra of the NW and SE clusters of the galaxy, which are known to display a variation in their broadband infrared colors, and use those spectra to study the physics of dust and radiation field in the galaxy. How different are the spectral slopes in these regions and what causes this difference? Are the metallicities derived from the infrared for these two regions also different and how do they compare to the optical? We will be able to answer these questions with the new proposed observation.
