Interstellar Medium
Stars and the interstellar medium are the two components of the Galaxy, and they have a close and intricate relationship. Stars form out of clouds of gas and dust. Stellar radiation and winds, as well as supernova explosions, play crucial roles in sculpting the ISM. The Canadian Galactic Plane Survey, for which Martin serves as a scientific director, is conducting an HI and continuum radio survey at 1 arc minute resolution. Combined with other data sets with similar resolution, this provides an excellent resource for studying the interplay between stars and the ISM. Much of the ISM-related research at CITA focusses on the process of star formation. We know that stars form when dense "cores" within molecular clouds collapse under their own self-gravity, but the details of the collapse have not yet been elucidated. Magnetic fields appear to play an important role. Recent Related Preprints
