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 please email Ben Weiner, bjw at as.arizona.edu, and Yujing Qin, qinyj at email.arizona.edu.
Galaxy Group for the 2022 Fall semester will host 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 MST. Changes to the schedule may happen occasionally to accommodate speaker schedules, especially those in other time zones. Talks are every 2nd week, occasionally with 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 per day, 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.

Previous Galaxy Group Schedules
Please contact Benjamin Weiner (bjw at as.arizona.edu) and Yujing Qin, qinyj at email.arizona.edu, to sign up for a talk.
The Galaxy Group email list has moved to a new UA listserv. This list now appears to accommodate addresses outside email.arizona.edu. If you have an email.arizona.edu and/or a UA NetID, address you can visit https://list.arizona.edu, sign in and look for the astro-galaxy-group list to issue a signup request or manage your subscription. If you have an address outside arizona.edu, try signing up through the list interface, and if that doesn't work, contact the organizers.
We have a separate email list for people who don't have an email.arizona.edu address (eg NOIRLab, LSST affiliates), but you should now be able to sign up to the main list. Please contact us if you have problems subscribing to these lists.
