In the order that you asked:
-- Yes, but not very well, I think we both helped teach a topic together as PhD students, but anyway I recognised the name instantly (in the source paper linked at the end of the article, they aren't mentioned in the article itself).
-- Yes, currently working as a particle physics postdoc somewhere.
-- But no, I never touched astronomy. Definitely was interested in it as a child, but it's been ages since I decided to focus on the world of the very small instead of the very large!
