Optical Imaging of Extended Star Formation in Nearby Spiral Galaxies with the One Degree Imager
American Astronomical Society, AAS Meeting #222, #214.12
Published in Jun 2013
We present initial results from a deep u and i-band imaging campaign using the One Degree Imager (ODI) on the WIYN 3.5-m telescope. We obtained images of several galaxies known to harbor extended regions of star formation beyond their optical disks, including NGC 2146, NGC 2403, NGC 2841, NGC 4254, and NGC 5055. We investigate the stellar component of these extended star-forming regions on large (>1 kpc) and small 50 pc) scales. We will compare the large-scale spatial structures, e.g. spiral arms or tidal features, found in our optical images to those found in GALEX UV images. Because we reach a finer resolution (0.8-1.2") as compared to the GALEX PSF, we will also determine the properties of small-scale structures, e.g. star clusters or individual stars, that exist in extended star-forming regions.
