Is the gamma-ray source 3FGL J2212.5+0703 a dark matter subhalo?
Is the gamma-ray source 3FGL J2212.5+0703 a dark matter subhalo?
In a previous paper, we pointed out that the gamma-ray source 3FGL J2212.5+\linebreak 0703 shows evidence of being spatially extended. If a gamma-ray source without detectable emission at other wavelengths were unambiguously determined to be spatially extended, it could not be explained by known astrophysics, and would constitute a smoking …
