The case for a galaxy without dark matter gets stronger

Remember that galaxy without dark matter ? Well there was one strangely deviant measurement that meant it might have had a dark halo after all. However, this is now shown not to be the case. It was strangely deviant because the measurement was simply wrong. Also, van Dokkum here officially respond to other criticism, though there are more details on his blog : https://www.pietervandokkum.com/ngc1052-df2

I'm very keen on figure 1, I think this is a nice and convincing comparison of the data with a theoretical Gaussian distribution.
