My teaching duties for the autumn semester end today, with the final lecture for the cosmology course focused on deriving the angular power spectrum of CMB temperature anisotropies (a lecture I always particularly enjoy, even though students seem to find it particularly difficult). Unlike the previous semester, this one was much lighter, as I only taught my cosmology course. It was once more very rewarding to interact with a bunch of bright students, whom I really hope enjoyed the course, and whose feedback I look forward to. While the next two months will be devoted to exams (teaching restarts at the end of February), I’ll be able to focus almost entirely on research, with the goal of wrapping up a few papers which are nearly done but just need a final push. So, once more, stay tuned for some interesting work which hopefully will appear in the coming months!
