Steward / NOIRLab Galaxy Group

Galaxy Group brings together people at Steward and NOIRLab broadly interested in galaxies, from galactic structure to extragalactic astronomy to cosmology. Talks about any aspect of interest to this audience are welcome. If you interested in giving a talk email Ben Weiner, bjw at, to inquire. We are seeking a co-organizer for Galaxy Group (duties include

Galaxy Group for the 2021 Fall semester is likely to feature a combination of in-person and virtual talks in a Steward zoom room, depending on circumstances. Speakers from outside Arizona are welcome and can present remote talks. The regular time is on alternate Mondays at 12-1 pm. Changes to the schedule may happen occasionally to accommodate speaker schedules, especially those in other time zones. Talks are every 2nd week with some talks in the "off" weeks as well.

The aim is to provide a low key environment for people to discuss work in progress. We can have one or two speakers, and talks should be 20-25 minutes long to allow time for questions during and after the talk. Speakers are strongly urged to present work in a less formal manner to encourage more discussion and interaction with the audience. Work in progress and talks that have a list of open questions are encouraged, as are reports from conferences, etc.
