About @gummiks

Hæ! I'm Guðmundur. Call me Gummi. It's simpler.


I am a 3rd year Fulbright and Leifur Eiríksson Foundation fellow doing a PhD in Astronomy & Astrophysics at Penn State University. I work with Suvrath Mahadevan (and so many other awesome team members) on the Habitable Zone Planet Finder (HPF) instrument, a near infrared ultra-stabilized spectrograph for the 10m class Hobby Eberly Telescope. In parallel, we are currently working on a design concept for the NN-EXPLORE Extreme Precision Doppler Spectrograph (EPDS) for the 3.5m WIYN telescope, whose main mission is to do extremely precise RV follow-up for future TESS targets.

My research up until now has focused on building, assembling, and testing various aspects of the HPF Environmental Control System, a system which has demonstrated sub-milli-Kelvin stability over more than two weeks. More about that in future posts.


I am enthusiastic about outreach. I am an active writer for Astrobites, and the HPF blog. When I have time, I enjoy making astronomy related youtube videos—see some of them on the HPF youtube channel! Most of them are related to HPF, illustrating the process of instrument building for astronomy.

If you have any questions, please don't hesitate to drop me a line.
