OBS: Galaxy Crawl is no longer running.

BUT if you are interested in presenting your work at UArizona, there are other opportunities like the Galaxy Lunch talks or flash talks.

This was a weekly, virtual talk series held in an informal format and centered on the topic of galaxy evolution theory.

The main purpose was to give students and postdocs in at University of Arizona exposure to other institutes when conferences were cancelled or going online due to the pandemic. But we also had a wide audience from other institutions calling in.

I started the sessions in March 2020 when lock-down forced everyone to work from home and it quickly built momentum since then, as a place where we felt less isolated and could share our research results.

Talks listed below are anywhere from 15 to 30 min long and can contain either published work or work in progress that needs comments or both!


Below is a list of all previous, with links to zoom recordings (the links stay active for 200 days after the day of recording!).
