This study looks at gravitational lensing and how foreground galaxies and their dark matter halos bend light. They modelled how Axion DM halos and WIMP DM halos would affect lensing. It turns out that Axion DM halos more closely represent what we see...in this model, of this system. But, it does add to previous data that favours Axions as DM candidates. And, I'm sure nFA would be delighted as he was in favour of Axions as DM candidates too.

I think nFA would have had much to say in favour of the article.
I did enjoy the comments after the article, so many MOND followers left in the world
