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 please email Ben Weiner, bjw at as.arizona.edu.

Galaxy Group for the 2023 Fall semester will host mostly in-person talks, also broadcast from a Steward zoom room, depending on circumstances. Speakers from outside Arizona are welcome. Remote talks are possible depending on schedule but we are trying to have more in-person events. The regular time is on alternate Mondays at 12-1 pm MST. Changes to the schedule may happen occasionally to accommodate speaker schedules. 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.

The Galaxy Group email list has moved to a new UA listserv, astro-galaxy-group at list.arizona.edu. This list now accommodates 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.
