I presented my research conducted at the Green Bank Observatory via a poster at the 235th Meeting of the American Astronomical Society (Jan 4-8, 2020). This is the premier astronomy conference in the U.S. As I'm part of a dedicated research program at my university (the Randall Research Scholars Program), every semester I participate in 8-12 hours of research each week. Each semester culminates in a presentation summarizing and explaining my research to fellow students, faculty, and interested members of the general public. The format for fall semesters is a 15 minute oral presentation with slides while the spring consists of a poster conference. At the end of both of my internships, I've presented my work to my advisors, colleagues, and other members of my sponsoring organization in the form of 10-20 minute oral presentations. I also participated in speech and debate throughout high school.
Significance of Research:
As radio telescope facilities grow larger with more antennas that observe wider frequency ranges, data rates are rapidly increasing. This necessitates an equivalent increase in data transfers, processing speeds, and emphasis on real-time analysis. My research aims to achieve this by creating a high-level radio telescope array data pipeline and algorithm interface intended for astronomers. I am working to reduce the gap between high-level science algorithm development (currently mainly in Python) and high-performance, production code by developing in the Julia programming language. Additionally, modern graphics processing units (GPUs) contain new hardware accelerators which have the potential to improve digital signal processing. Combining the aspects above, the goal of my research is to improve the performance and programmability of radio telescope array data processing pipelines. This will allow for increased real-time data analysis by astronomers - accelerating discoveries such as the search for technological signatures from extraterrestrial civilizations.
Uniqueness of Research:
This research explores improvements in high-performance data processing pipelines to enable easier development and implementation of array-based radio astronomy observations. Specifically, this research is geared towards improving the search for technological signatures from civilizations beyond Earth.
