Observing proposal accepted !

Remember back when I had fifty million things to do all at once instead of one huge, all-consuming series of PowerPoint presentations to prepare ? One of which being a proposal to the IRAM 30m telescope in Spain, which we wrote (somehow) in two days, from scratch. Well we got the time ! Even better, we got 36 hours when we only asked for 21. Best of all, the scheduling letter is written in comic sans... say what you will, it's a lovely font. :P (No idea why we got the extra time, they only sent the scheduling letter and not the comments on the proposal yet)

We're going to be observing some ultra-diffuse galaxies in the CO line to see if they have molecular gas. With that we hope to understand why the things are so damn bad at forming stars.

And now back to my lord and master, PowerPoint...

    ,,, so I started down the rabbit hole, on the strength of this post. Much talk about dark matter in these ultra diffuse galaxies comes bubbling up in the search engines. Where will your team be looking?

    Dan Weese We're looking in the Pegasus group/cluster. We have a deep HI cube for this region, which I catalogued earlier in the year because I was sick of running simulations. By happy coincidence, a completely separate group happen to have run a UDG-finding code over the same region, and some of our sources match :

    And more on UDGs :
