AST Colloquium
Astronomical instruments on a chip – Getting ready for the next-generation telescopes
Dr. Pradip Gatkine
Assistant Professor, Physics and Astronomy Department
UCLA
Abstract:
Astrophotonics is the application of versatile photonic technologies to channel, manipulate, and disperse guided light from one or more telescopes to achieve scientific objectives in astronomy in an efficient and cost-effective way. The photonic platform of guided light in fibers and waveguides has opened the doors to next-generation instrumentation for both ground- and space-based telescopes. Utilizing the photonic advantage is a promising approach to massively miniaturize the next generation of spectrographs. Dr. Gatkine will discuss some of their recent results from their efforts to design and fabricate high-throughput on-chip astrophotonic spectrographs. These devices are ideally suited for enabling exciting science cases, such as measuring exoplanet masses and characterizing exoplanet atmospheres. He will also discuss specific approaches to make this technology science-ready for the Extremely-Large-Telescope era.
Speaker Bio:
Pradip Gatkine is an assistant professor of Physics and Astronomy at UCLA. He was a NASA Hubble Fellow at Caltech till March 2024. He received his PhD in Astronomy from the University of Maryland in July 2020. His research includes the development of next-generation astrophotonic instrumentation for large telescopes. He is currently developing on-chip high-resolution spectrographs, filters, and beam combiners for astronomical telescopes with the aim of detecting and characterizing habitable exoplanets. He also co-led the Astrophotonics Roadmap 2023 on astrophotonics in the next decade.
