Galaxy Discussion Group (2014 - 2015)

This is the page for the 2014/2015 NRAO/UVA Galaxy Discussion Group. The purpose of this group is to discuss various topics related to galaxies, AGN, and the evolution of both. The discussions are informal and are led by volunteers depending on the topic of the day, which we are attempting to broadly organize by a ~monthly theme. Contact Jen Donovan Meyer (jmeyer at to be added to the email list for this group.


Tuesdays from 3:30 to 4:30 in the NRAO Library.
