Abstract: This traditional "Show and Tell" colloquium is especially special this year because it will be the first in person since March 2020. Undergraduate researchers, grad students, postdocs, scientists, and faculty working in Astronomy are encouraged to introduce themselves in 2 minutes, accompanied by one (and only one) slide. This stringent format is necessary because there are so many of us. Even so, note the early start time and extra time alloted.
