Stony Brook University faculty and students are actively involved in the newly constructed Vera C. Rubin Observatory, located in the Andes Mountains in Chile. This facility is set to conduct a 10-year survey of the sky using the largest camera ever built. The project aims to create the Legacy Survey of Space and Time (LSST), capturing detailed images of the cosmos.
The Rubin Observatory recently showcased its capabilities at an event in Washington D.C., where Stony Brook researchers joined global colleagues for a “First Look Watch Party.” The observatory’s main scientific goals include exploring transient phenomena, mapping our galaxy and solar system, and studying cosmology to understand dark matter and dark energy.
Stony Brook’s involvement primarily focuses on cosmology. Researchers from the university are part of two major collaborations: the LSST Dark Energy Science Collaboration (DESC) and the LSST Strong Lensing Science Collaboration (SLSC). Chang Kee Jung, chair of Stony Brook’s Department of Physics and Astronomy, emphasized the importance of this project for advancing knowledge about dark matter and dark energy.
Anja von der Linden, an associate professor at Stony Brook, has been with DESC since its inception in 2012. She highlighted Rubin’s ability to image the entire southern night sky every three nights over a decade. This effort will generate substantial data, aiding astronomers in uncovering cosmic secrets.
Other faculty members involved include Simon Birrer, co-chair of SLSC; Vivian Miranda, active in DESC; and Neelima Sehgal, who combines Rubin findings with other experiments. They emphasize that collaborative efforts will be crucial as Rubin is expected to significantly impact strong lensing science.
The Stony Brook team includes early career researchers like Dr. Narayan Khadka and several graduate students preparing for analyses with LSST data. Additionally, some former graduates now hold key roles related to Rubin operations.
