Gebhardt said his team had developed a "resampling technique" that infers a spatial resolution of the Hubble data that is improved by a factor of two,
Hm, claims of improvement in spatial resolution always makes me veeeery skeptical. Unless they can prove that the resampling technique works, by showing that it correctly reproduces an image taken with higher resolution, I just don't believe it. And with galaxies and with the HST (that has pretty much the best resolution right now (until optical interferometers get into "everyday" use)), you can't do that.
That doesn't mean I reject this study, but I would view it with additional skepticism.
