Coffee at 7 pm usually isn't a problem...

  1. Dendrogram analysis of turbulent simulations. What do the structures look like? Mostly for visualization in a talk, but perhaps the start of a paper. Are the high-density substructures too small to collapse? Too hot?
  2. A deep GBT+AO observation of the center of the G49 40km/s cloud. Can we perform the same measurement as I did originally against a uniform backlight? Will that provide new information
  3. Corollary to 2: In simulations, what effect does a varying size and brightness backlight have on the inferred density?
  4. Measure the distance to the G49 cloud with NIR extinction. Keep working with Jonathan Foster on that...
  5. Test the Cepheid / RR Lyrae distance method on the G49 cloud. It's close enough that the targets should be bright. Start off with 1-hour pilot (DD?) on the most distant star with a "guaranteed" CO detection, then propose a longer project to begin using the bisector approach to determine its true distance.
  6. Eta Car ALMA. Basically, same thing, but now invoke the SN 1987A CO detection. Eta is the closer laboratory, and it must have similar shock physics...
  7. H3+ in the CMZ with Juergen. Talk to Tom Geballe about H3+ and CO absorption. Is it possible to measure CO absorption to red giants?
