Supernovae (SNe), through their diffuse supernova remnants (SNRs), are primarily responsible for the injection of energy and heavy elements into the interstellar medium (ISM). SNe provide most of the hot gas component of the ISM, and through collective inputs to structures such as superbubbles and supergiant shells, can transfer hot gas into a galaxy halo. The energy and heavy elements influence future generations of star formation in a galaxy and have a profound effect on galaxy evolution.
We have undertaken a long-term multiwavelength study of SNRs in the Magellanic Clouds (MCs). These galaxies contain extraordinary samples of SNRs at a wide variety of types, ages, evolutionary stages, and environments. The known, common distances and low obscuration of the MCs allows their SNRs to be studied as members of an increasingly well-understood population. The current generation of instruments, including the Chandra and XMM X-ray satellites and the Hubble and Spitzer Space Telescopes, have allowed high-resolution examinations of these SNRs at levels comparable to those for Galactic objects. Crucially, new surveys of the MCs with the Australia Telescope Compact Array in radio, and the Magellanic Clouds Emission-Line Survey at CTIO, have providded a wealth of data on each of these objects.
We have used these resources to build up a database of information on the Magellanic Cloud SNRs, in order to make the data and findings easily accessible to other researchers. We here present the current state of the database and future plans for the inclusion of more information. The authors thank NASA's LTSA grant NNX08AM54G for support of this long-term project.
