On a weird paper claiming to have found a sample of very red, gas-rich galaxies not forming stars. In the original draft (which I'd downloaded some months ago) they didn't have any images of their sample, but presented a very nice narrative of how these were definitely very strange objects. But when I checked the images manually, which they now include in an appendix in the final version, many of them look like normal spiral galaxies. With great big blue spiral arms, it's very difficult to believe they really have unusual low levels of star formation. You just don't get blue structures like this without forming stars. For sure the central regions may be quenched, but surely not the whole galaxy as they claim.

I should probably try and read the new version but I just don't want to.
