Research at the Yale Summer Program in Astrophysics

Research at YSPA involves teams of four students collaborating on an astrophysical project that entails acquiring data from telescopes at the Leitner Observatory (LFOP), including the 0.4-meter Ritchey-Chretien Telescope featured alongside YSPA students.

Data collection extends to remote New Mexico, California, Chile, and Australia observatories. Once an ample dataset is obtained, students utilize the Python programming language and scientific Python libraries to construct a model that best fits and elucidates their data.

While the specific research focus at YSPA varies annually, the consistent theme involves formulating a scientific model for a phenomenon using data directly collected by the students from LFOP and other remote telescopes. 

In the 2023 session, all students concentrated on modeling the photometric light curves and spectra of extra-galactic supernovae. These colossal stars, exploding with remarkable luminosity in remote galaxies, provide insights into the physics of stellar core collapse. 

Analyzing the fading patterns of these exploding stars over time offers potential revelations about the stellar populations of distant galaxies. Remarkably, some cases even enable the independent measurement of a galaxy’s distance and determination of the Universe’s expansion rate.

Upon concluding the program, each research team compiles a report on their project in the format of a scientific paper. Results are presented at a mini-conference, allowing for valuable feedback from Yale Astronomy faculty and fellow students.

Post-YSPA, some students may choose to develop further and expand their research project for participation in science fairs, talent search programs, or as a senior capstone project at their high school.

In certain instances, these projects may evolve into published papers in refereed science journals.
