The Abundance Gradient in the Extremely Faint Outer Disk of NGC 300
In an earlier work, we showed for the first time that the resolved stellar disk of NGC 300 is very extended with no evidence for truncation, a phenomenon that has since been observed in other disk galaxies. We revisit the outer disk of NGC 300 in order to determine the metallicity of the faint stellar population. With the Gemini Multi Object Spectrograph camera at Gemini South, we reach 50% completeness at (g′, i′) = (26.8-27.4, 26.1-27.0) in photometric conditions and 07 seeing. At these faint...[Show more]
