SDSS IV MaNGA: Discovery of an H Alpha blob associated with a dry galaxy pair - Ejected gas or a “dark” galaxy candidate?

We report the discovery of a mysterious giant Hα blob that is ∼8 kpc away from the main MaNGA target 1-24145, one component of a dry galaxy merger, and has been identified in the first-year SDSS-IV MaNGA data. The size of the Hα blob is ∼3-4 kpc in radius, and the Hα distribution is centrally concen...
