- Abstract: If the weather is nice, we’ll meet on Bascom Hill (in front of Birge Hall). Feel free to bring your lunch. We’ll borrow cornhole and ladder toss from the L&S Dean’s Office and play outside for 30 minutes. Some of us will probably walk up together, meeting in the courtyard between Chamberlin and Sterling ~12:25 – feel free to walk with us! No need to sign up – just come join us!

- Small-Scale Structure of the "Dark ISM"
- Time: 3:30 pm - 4:30 pm
- Place: 4421 Sterling Hall
- Speaker: Joanne Dawson, Macquarie University
- Abstract: It is now known that a significant fraction of the Milky Way ISM resides in a so-called "dark" phase, usually defined as a mixture of cold, optically thick HI and diffuse molecular hydrogen with densities that are insufficient to form and shield CO. I will present a brief overview of the so-called "Dark ISM" -- where it resides, how much there is, and its characteristic properties. I will then focus on two aspects of structure in the dark gas: (1) AU-scale structures in the cold atomic medium, including their possible implications in measuring the fraction of cold/opaque HI, and (2) underlying structure in CO-dark molecular gas that can give rise to very broad, very weak molecular spectral features in OH and HCO+. I will introduce two ongoing observational experiments that may further constrain both of these phenomena.
