Of course, they have not observed any kind of dark matter structure. They have just observed a distribution of gravitational lensing and they ASSUME that it is due to dark matter. Dark matter still is a purely hypothetical concept which can easily be avoided by adopting a modification of the present theory of gravitation. There exist various alternatives to dark matter (as a quick search on the Arxiv web site shows) and several of these have been published in peer reviewed journals. A recent addition is my own theory:
