High-Velocity Clouds (HVCs), those assemblies of gas around galaxies that do not follow galactic rotation, have been enigmatic since their discovery almost 60 years ago. Recent advances both observational and theoretical have clarified their properties and their importance to galaxy formation and evolution. To explore this topic further a Green Bank Workshop on “Galactic and Extragalactic High-Velocity Clouds” will be held June 26-29, 2022. It will bring together scientists with a diverse range of interests for lively discussions of the latest observations, computational models and theoretical considerations.
The Workshop will be held at the Green Bank Observatory, where the great natural beauty and intimate setting produce meetings characterized by a high level of interaction. Because of logistical considerations, attendance will be limited to 45 participants.
Lodging
Lodging will be at the Observatory or at nearby locations. All meals will be served in the Observatory Cafeteria. A single fee of $550 per participant will cover all local expenses including lodging and meals. It
may be possible to waive this cost for some of the participants.
Accommodations for accompanying persons and child care will be available.
Travel Information
The easiest way to get here is to follow the directions on our “Getting Here” page. Please do note that some GPS systems do not always give the best route to the Green Bank Observatory, and nothing beats the good old-fashioned paper map for navigation.
We will attempt to coordinate ride-sharing from airports if there is interest.
Workshop Schedule
The workshop will begin with an informal reception at Sunday, June 26. Formal sessions will start on Monday June 27 and continue through the morning of June 29. There will be evening sessions June 27 and June 28. The workshop will end with lunch on Wednesday June 29. A detailed program will be available at a later date from this webpage.
