The weekly APS Colloquium provides a regular venue for all departmental members to meet and hear about current research topics from both CU and external speakers. Refreshments are served before each talk and graduate students meet with the speaker for lunch that day in a “collunchium.”  All members of the department are invited to dinner with the weekly speaker. APS is also invited to regular talks at the Physics Department and our affiliated research institutions (CASA, JILA and LASP).

A departmental coffee hour and an Astro-ph discussion session are scheduled each week. Regular events include undergraduate and graduate student welcome and commencement events, informal happy hour gatherings, and faculty-hosted social events.
