Cristóbal Armaza

Astronomy & Space Sciences


A third-year student, Cristóbal's main research interests include theoretical astrophysics, general relativity, compact objects, and cosmology. As a member of the Cornell numerical relativity group, he contributes to the development of SXS Collaboration's SpECTRE, an open-source code for astrophysics and gravitational physics whose primary goal will be to simulate with high accuracy the evolution of gravitational wave sources.

Cristóbal is also part of the Cornell Ask an Astronomer team, where he answers astrophysics questions coming from all over the globe. In the past, he has also served as a teaching assistant for several astronomy and physics courses, as well as a tutor for the Chile-based "Bling Bling Universe" project, where high-school students get introduced to basic concepts in astrophysics and data analysis through weekly workshops.

Born and raised in Chile, he obtained a BS and a MS in astrophysics from Pontificia Universidad Católica de Chile before moving to Ithaca. Besides science and outreach, Cristóbal also enjoys playing music, juggling, outdoor activities and helping people learn Spanish.
