I was wondering if there is a paper or article which goes into up to date deeper summarization of all problems and anomalies attributed currently to Dark Matter and Dark Energy?
I do know that the DES is just releasing its catalog of 700M+ astronomical objects. It will probably be years before analysis bears fruit. And there is always the risk of raising more questions than answers.

Your question also reminds me of the "20 Unsolved Problems in Physics" that is now more than 20 years old. It was thought that many of these would no longer be classified as "unsolved" by now ;)
Yeah the DES data would be fantastic resource when released. But wondering if it is worth compiling all open questions, if not already a resource. As in order to sift through data it's important have a complete picture of the full set of open questions we are dealing with.
