HI 21 cm mapping of the Gem OB1 star-forming region

We propose to map the H I 21 cm line over a field that encompasses the Gem OB1 association, a region of vigorous massive star formation. This area of sky has been studied extensively at other wavelengths, so that the stellar, molecular, ionized, and dust components are well-known. We want to exploit the new rapid mapping capability with ALFA to obtain a fully sampled map of H I over a 9 deg x 10 deg field at 3' resolution. The key question we are addressing in this proposal is, how does the atomic component of the ISM fit into the cycling of matter through H I - H2 - H II, energized by OB stars through their UV radiation, winds, and eventual supernova explosions?The Gem OB1 region is an excellent example in which to study these processes.
