Spitzer observations of star formation in the extreme outer disk of M83 (NGC5236)
evolution individual (M83)
2014/12/23
Spitzer Infrared Array Camera (IRAC) observations of two fields in the extended UV disk (XUV-disk) of M83 have been recently obtained, ~3 R HII away from the center of the galaxy (R HII = 6.6 kpc). Ga...
We present spectroscopic observations and chemical abundances of 16 planetary nebulae (PNe) in the outer disk of M31. The [O III] 4363 line is detected in all objects, allowing a direct measurement of...
Unusually Luminous Giant Molecular Clouds in the Outer Disk of M33
Cosmology and Extragalactic Astrophysics (astro-ph.CO)

We use high spatial resolution (~7pc) CARMA observations to derive detailed properties for 8 giant molecular clouds (GMCs) at a galactocentric radius corresponding to approximately two CO scale length...
