Are the HI properties of J1649+26 consistent with a regular spiral galaxy?

We have found the best example to date of a grand-design spiral galaxy associated with a double-lobed radio source. Leading galaxy formation models do not account for these, consequently this discovery is significant. Spiral galaxies are known to host large amounts of HI in a rotationally stable disk. Conversely, the host galaxies of double-lobed radio sources may be void of HI emission, or contain tumultuous HI disks with large velocity dispersions. Here we submit a Short Proposal to Arecibo Observatory to measure the HI characteristics of this paradoxical source and determine whether they are consistent with a regular spiral galaxy.
